Define: Bitcoin Halving? - Quora

Ultimate glossary of crypto currency terms, acronyms and abbreviations

I thought it would be really cool to have an ultimate guide for those new to crypto currencies and the terms used. I made this mostly for beginner’s and veterans alike. I’m not sure how much use you will get out of this. Stuff gets lost on Reddit quite easily so I hope this finds its way to you. Included in this list, I have included most of the terms used in crypto-communities. I have compiled this list from a multitude of sources. The list is in alphabetical order and may include some words/terms not exclusive to the crypto world but may be helpful regardless.
2FA
Two factor authentication. I highly advise that you use it.
51% Attack:
A situation where a single malicious individual or group gains control of more than half of a cryptocurrency network’s computing power. Theoretically, it could allow perpetrators to manipulate the system and spend the same coin multiple times, stop other users from completing blocks and make conflicting transactions to a chain that could harm the network.
Address (or Addy):
A unique string of numbers and letters (both upper and lower case) used to send, receive or store cryptocurrency on the network. It is also the public key in a pair of keys needed to sign a digital transaction. Addresses can be shared publicly as a text or in the form of a scannable QR code. They differ between cryptocurrencies. You can’t send Bitcoin to an Ethereum address, for example.
Altcoin (alternative coin): Any digital currency other than Bitcoin. These other currencies are alternatives to Bitcoin regarding features and functionalities (e.g. faster confirmation time, lower price, improved mining algorithm, higher total coin supply). There are hundreds of altcoins, including Ether, Ripple, Litecoin and many many others.

This post will show you the best ways to buy litecoins using many different payment methods and exchanges for each method.
Before you start, make sure you have a good litecoin wallet to store your LTC. NEVER store your litecoins on a crypto exchange.

Buy Litecoin with Credit Card or Debit Card

Let’s dive into some of the exchanges supporting Litecoin credit card purchases.
These exchanges are our favorite ways to buy.

Coinbase

Coinbase is the easiest way to buy litecoins with a credit card.

The fees will come out to 3.99% per purchase.

Coinmama has some of the highest limits among credit card exchanges.

Buy Litecoin with Bank Account or Bank Transfer

Coinbase

Coinbase is the easiest way to buy litecoins with a bank account or transfer.
Coinbase, like is is for credit cards, is available in the United States, Canada, Europe, UK, Singapore, and Australia.
Coinbase is one of primary exchanges used to buy Litecoins.
Americans can use ACH transfer (5–7 days wait), and Europeans can use SEPA transfer (1–3 days wait).
The fees will come out to 1.49% per purchase.

BitPanda

BitPanda is based in Austria and is a crypto brokerage service. You can buy using SEPA transfer from most European countries. You can also use SOFORT, NETELLER, or GiroPay.

CEX.io

CEX.io also supports litecoin buys via bank account. This is via wire transfer for US citizens, SEPA for Europe, and SWIFT for the rest of the globe.

Binance is now one of the largest if not the largest cryptocurrency exchange in the world. It supports bank and card purchases of Litecoin as well as Litecoin trading pairs with Bitcoin and Etehreum.

Get a Litecoin Wallet

Before we move onto other options:
Never store your litecoins on an exchange!
Always withdrawal your litecoin to an offline cryptocurrency wallet like the Ledger Nano S or any other wallet that you control.
The Ledger Nano S and TREZOR are the best options for secure storage.

Other Methods to Buy Litecoin

If you don’t have a card or want to avoid the high fees, you can use the following methods to buy Litecoin as well.
Find out which one works best for you.

Buy Litecoin with PayPal

Unfortunately, there is no easy way to buy Litecoin with PayPal. Other sites will tell you that cex allows for this, but that is no longer the case.
You can, however, now use eToro to buy Litecoin, unless you live in the United States.
If you live in the US, the only way to buy Litecoin with Paypal is to buy Bitcoin using paypal, and then use the Bitcoins to buy Litecoin. You can easily buy Bitcoin using Paypal on Local Bitcoins. Once you have Bitcoin, you can use an exchange like Coinbase Pro to swap the Bitcoin for Litecoin.

Buy Litecoin with Cash

There is no good way to buy litecoins with cash. LocalBitcoins is the most popular way to buy bitcoins with cash, and it does not have Litecoin support. Other popular cash to Bitcoin exchanges like BitQuick and Wall of Coins also do not support LTC. So you will have to first buy bitcoins with cash then exchange them for LTC using the method described below.
The same goes for Bitcoin ATMs. Most do not support Litecoin. So if you want to buy litecoins at a Bitcoin ATM you first have to buy bitcoins and then trade the BTC for litecoins.

Buy Litecoin with Bitcoin

If you already have Bitcoins then it is VERY simple to convert some of your BTC to litecoins.
You just need to find an exchange with the LTC/BTC pair, which is most exchanges since LTC/BTC is a very popular pair to trade.

Buy Litecoin with Skrill

BitPanda, mentioned above, also accepts Skrill payments for LTC. The fees will vary and are simply included in your buy price.

Cryptmixer

Cryptmixer is probably the fastest way to convert BTC to Litecoin. You just enter the amount of LTC you want to buy, and give them a LTC address. Then they will tell you how much BTC to send to their address. Once your BTC is sent, you will have LTC delivered to your wallet very shortly after.

Buy Litecoin with Ethereum

Ethereum has experienced a massive price rise. Nearly a year ago it was $10, and now at over $500, many want to move some of their ETH gains into other coins like Litecoin.
Litecoin has very good liquidity, and is very popular among traders especially in China.
So this guide is going to show you how to buy litecoins with Ethereum. We will show some of the best exchanges you can use, and the pros and cons of using different types of exchanges over the other.

Cryptmixer

Cryptmixer is one of the most unique exchanges, and also one of the fastest ways to convert your ETH to LTC.
With Cryptmixer you do not even need to store your money with the exchange, meaning you are at very little risk of getting your funds stolen.
With Cryptmixer you simply specify the amount of LTC you want to buy, and specific the address to where your litecoins should be sent and within 30 minutes you will have LTC delivered to your wallet.

Poloniex

Poloniex is the world’s largest altcoin exchange. However, there is a huge downside to using Poloniex to convert your ETH to LTC:
Poloniex does not have a LTC/ETH market, meaning you have to first trade your ETH to BTC, and then trade your BTC for LTC.
While this method works, you will have to make multiple trades and also pay fees twice.

ShapeShift

Shapeshift is basically the same as Cryptmixer, and was actually the first company to come up with the concept of an exchange that does not hold your own funds.

Frequently Asked Questions About Buying Litecoin

Many of you may still have lots of questions about how to buy Litecoin.
Odds are we have answered almost any question you could think of below.
We will aim to answer many of the most common questions relating to buying Litecoin.

Why are there limited options to buying Litecoin using other altcoins?

The issue in all crypto markets is liquidity. As the space gets bigger, the liquidity also gets better. But as of now, the only VERY liquid cryptocurrency is Bitcoin. So exchanging two altcoins between each other is often harder than if BTC was involved on one side of the trade.

How much is a Litecoin worth?

Like all currencies, the value of Litecoin changes every second. The value of Litecoin also depends on the country you are in and the exchange you are trading on. You can find the most up to date price on Coinbase.

How do I buy Ripple (XRP) with Litecoin?

The best way to buy Ripple using Litecoin is to either use a non KYC exchange like Cryptmixer or start an account on Binance or Coinbase Pro and sell your Litecoin for Ripple. Look for LTC/XRP trading pairs, and make your trade.

How long does Litecoin take to confirm?

Litecoin blocks are added ever 2 and a half minutes. That means you should get one confirmation every two and a half minutes. This can vary if it takes miners longer to discover a block, but the difficulty of the finding a block should change proportionate to the hashing power on the network so that a block gets added approximately every 2.5 minutes.
If you are trying to send money to a merchant, they may require more than one confirmation before they send you products. If you are depositing on an exchange, they may also require three or more confirmations before they credit your account.

How many Litoshis make one Litecoin?

one hundred million (100,000,000) Litoshis make one (1) Litecoin.

Where do I store Litecoin?

The best place to store litecoin is on a hardware wallet. You can find the best one for you on our page dedicated to hardware wallets.

When is the Litecoin halving?

The expected date of the next Litecoin block reward halving is August 7th, 2023.

Why can litecoin take so long to buy?

Litecoin can take long to buy because the legacy banking system is very slow. If you are buying with another cryptocurrency, you will see how fast it is to buy!
Bank transfer in the USA, for example, take about 5 days to complete. So any purchase of Litecoin made with a US bank transfer will take a minimum of 5 days.

How do I buy Litecoin with Paypal?

Unfortunately, there is no easy way to buy Litcoin with PayPal. Other sites will tell you that cex allows for this, but that is no longer the case.
You can, however, now use eToro to buy Litcoineum, unless you live in the United States.
If you live in the US, the only way to buy Litcoin with Paypal is to buy Bitcoin using paypal, and then use the Bitcoins to buy Litcoin. You can easily buy Bitcoin using Paypal on Local Bitcoins. Once you have Bitcoin, you can use an exchange like Cryptmixer to swap the Bitcoin for Litcoin.

Can you buy partial litecoins?

Yes, litecoin, like Bitcoin, is divisible to many decimal places so you can buy 0.1 LTC, 0.001 LTC, etc.

Can you sell litecoin?

Yes, you can sell LTC on most of the exchanges mentioned above. The fees, speed, and privacy is the same in most cases.

Can anyone buy litecoins?

Anyone is free to buy litecoins, as long as you find an exchange that supports your country. Most cryptocurrency wallets do not require ID to sign up so you can always make a wallet and get paid in litecoin, too.

Which payment method is best to use?

For speed, credit card will likely be fastest. For larger amounts, bank transfer is best. For privacy, it’s best to buy bitcoins with cash and then trade for litecoins using Cryptmixer or Shapeshift.

Is it better to mine or buy litecoins?

If you have cheap electricity, it might be worth it to mine litecoins. If you have solar power or just want to mine for fun then it could be worth it. Otherwise, it’s probably better just to buy.
Mining is constantly changing and small changes in Litecoin price or electricity can greatly affect your profitability.

What should I do with my litecoins once I buy?

You should immediately move your litecoins into a secure wallet. You should never leave your litecoins on an exchange. There have been countless hacks in cryptocurrency since Bitcoin was created in 2009. Hundreds of thousands of people have lost money. So buy your litecoins, and then instantly send them into a wallet you control so you are not at risk of losing money to a hack or scam.

Round up of Cryptocurrency News #2 Week 13/07 - 19/07

Round up of Cryptocurrency News #2 Week 13/07 - 19/07
So much has happened this week! We saw a capitulation point of bitcoin before bears took over and we saw the selling pressure push Bitcoin down toward the $9000USD mark then move back up above $9100USD So far it has been a stable hold, however we may see some more action within the coming weeks.
 
Widespread scamming within the Twitter-sphere, Youtube and other platforms as Bitcoin and other cryptocurrencies may seem like fair game. Cryptocurrencies providing big payouts for scammers without the ability for reversals of accounts. Remember if something seems too good to be true, do some research or just plain do not respond/believe it. Stay safe and careful with your funds!
 
On the brightside, there has been even more adoption of cryptocurrencies as rumours of Paypal utilising cryptocurrency has been confirmed as they are developing crypto capabilities. In addition to this we received exciting news at the start of this week about Binance partnering with Swipe (SXP) and offering a debit card to spend BNB, SXP, BTC and BUSD. ( I will be keeping a swift eye on BNB and Swipe as its utilisation as tokens has just increased 43 fold).
 
Positive news for the Bitcoin network as its hashrate reaches all time high which helps to secure the network further even though mining profits have dropped by 50% from the recent halving. If you didn't know already the last Bitcoin will be expected to be mined in 2140 with its difficulty ever increasing and each time securing the network further. Processing units will have to become faster, stronger and most importantly more cost effective to continue to entice miners for the block rewards and further renewable energy practices.
 
Furthermore we can see Central banks and countries discussing and developing Central Bank Digital Currencies (CBDC). Read more about it here https://www.investopedia.com/terms/c/central-bank-digital-currency-cbdc.asp and check out some of the developments in the world above. This shows the popularity and strong nature of cryptocurrencies. As the saying goes "If you cant beat them, JOIN them".
 
Overall, very solid week full of adoption, animation and anticipation. Another post next week for a weekly round up! See you then but in the mean time join us at our Gravychain Discord.

A Beginners Guide to Bitcoin, Blockchain & Cryptocurrency

As cryptocurrency, and blockchain technology become more abundant throughout our society, it’s important to understand the inner workings of this technology, especially if you plan to use cryptocurrency as an investment vehicle. If you’re new to the crypto-sphere, learning about Bitcoin makes it much easier to understand other cryptocurrencies as many other altcoins' technologies are borrowed directly from Bitcoin.
Bitcoin is one of those things that you look into only to discover you have more questions than answers, and right as you’re starting to wrap your head around the technology; you discover the fact that Bitcoin has six other variants (forks), the amount of politics at hand, or that there are over a thousand different cryptocurrencies just as complex if not even more complex than Bitcoin.
We are currently in the infancy of blockchain technology and the effects of this technology will be as profound as the internet. This isn’t something that’s just going to fade away into history as you may have been led to believe. I believe this is something that will become an integral part of our society, eventually embedded within our technology. If you’re a crypto-newbie, be glad that you're relatively early to the industry. I hope this post will put you on the fast-track to understanding Bitcoin, blockchain, and how a large percentage of cryptocurrencies work.

Community Terminology

Altcoin: Short for alternative coin. There are over 1,000 different cryptocurrencies. You’re probably most familiar with Bitcoin. Anything that isn’t Bitcoin is generally referred to as an altcoin.
HODL: Misspelling of hold. Dank meme accidentally started by this dude. Hodlers are much more interested in long term gains rather than playing the risky game of trying to time the market.
TO THE MOON: When a cryptocurrency’s price rapidly increases. A major price spike of over 1,000% can look like it’s blasting off to the moon. Just be sure you’re wearing your seatbelt when it comes crashing down.
FUD: Fear. Uncertainty. Doubt.
FOMO: Fear of missing out.
Bull Run: Financial term used to describe a rising market.
Bear Run: Financial term used to describe a falling market.

What Is Bitcoin?

Bitcoin (BTC) is a decentralized digital currency that uses cryptography to secure and ensure validity of transactions within the network. Hence the term crypto-currency. Decentralization is a key aspect of Bitcoin. There is no CEO of Bitcoin or central authoritative government in control of the currency. The currency is ran and operated by the people, for the people. One of the main development teams behind Bitcoin is blockstream.
Bitcoin is a product of blockchain technology. Blockchain is what allows for the security and decentralization of Bitcoin. To understand Bitcoin and other cryptocurrencies, you must understand to some degree, blockchain. This can get extremely technical the further down the rabbit hole you go, and because this is technically a beginners guide, I’m going to try and simplify to the best of my ability and provide resources for further technical reading.

A Brief History

Bitcoin was created by Satoshi Nakamoto. The identity of Nakamoto is unknown. The idea of Bitcoin was first introduced in 2008 when Nakamoto released the Bitcoin white paper - Bitcoin: A Peer-to-Peer Electronic Cash System. Later, in January 2009, Nakamoto announced the Bitcoin software and the Bitcoin network officially began.
I should also mention that the smallest unit of a Bitcoin is called a Satoshi. 1 BTC = 100,000,000 Satoshis. When purchasing Bitcoin, you don’t actually need to purchase an entire coin. Bitcoin is divisible, so you can purchase any amount greater than 1 Satoshi (0.00000001 BTC).

What Is Blockchain?

Blockchain is a distributed ledger, a distributed collection of accounts. What is being accounted for depends on the use-case of the blockchain itself. In the case of Bitcoin, what is being accounted for is financial transactions.
The first block in a blockchain is referred to as the genesis block. A block is an aggregate of data. Blocks are also discovered through a process known as mining (more on this later). Each block is cryptographically signed by the previous block in the chain and visualizing this would look something akin to a chain of blocks, hence the term, blockchain.
For more information regarding blockchain I’ve provided more resouces below:

What is Bitcoin Mining

Bitcoin mining is one solution to the double spend problem. Bitcoin mining is how transactions are placed into blocks and added onto the blockchain. This is done to ensure proof of work, where computational power is staked in order to solve what is essentially a puzzle. If you solve the puzzle correctly, you are rewarded Bitcoin in the form of transaction fees, and the predetermined block reward. The Bitcoin given during a block reward is also the only way new Bitcoin can be introduced into the economy. With a halving event occurring roughly every 4 years, it is estimated that the last Bitcoin block will be mined in the year 2,140. (See What is Block Reward below for more info).
Mining is one of those aspects of Bitcoin that can get extremely technical and more complicated the further down the rabbit hole you go. An entire website could be created (and many have) dedicated solely to information regarding Bitcoin mining. The small paragraph above is meant to briefly expose you to the function of mining and the role it plays within the ecosystem. It doesn’t even scratch the surface regarding the topic.

How do you Purchase Bitcoin?

The most popular way to purchase Bitcoin through is through an online exchange where you trade fiat (your national currency) for Bitcoin.
Popular exchanges include:
  • Coinbase
  • Kraken
  • Cex
  • Gemini
There’s tons of different exchanges. Just make sure you find one that supports your national currency.

Volatility

Bitcoin and cryptocurrencies are EXTREMELY volatile. Swings of 30% or more within a few days is not unheard of. Understand that there is always inherent risks with any investment. Cryptocurrencies especially. Only invest what you’re willing to lose.

Transaction & Network Fees

Transacting on the Bitcoin network is not free. Every purchase or transfer of Bitcoin will cost X amount of BTC depending on how congested the network is. These fees are given to miners as apart of the block reward.
Late 2017 when Bitcoin got up to $20,000USD, the average network fee was ~$50. Currently, at the time of writing this, the average network fee is $1.46. This data is available in real-time on BitInfoCharts.

Security

In this new era of money, there is no central bank or government you can go to in need of assistance. This means the responsibility of your money falls 100% into your hands. That being said, the security regarding your cryptocurrency should be impeccable. The anonymity provided by cryptocurrencies alone makes you a valuable target to hackers and scammers. Below I’ve detailed out best practices regarding securing your cryptocurrency.

Two-Factor Authentication (2FA)

Two-factor authentication is a second way of authenticating your identity upon signing in to an account. Most cryptocurrency related software/websites will offer or require some form of 2FA. Upon creation of any crypto-related account find the Security section and enable 2FA.

SMS Authentication

The most basic form of 2FA which you are probably most familiar with. This form of authentication sends a text message to your smartphone with a special code that will allow access to your account upon entry. Note that this is not the safest form of 2FA as you may still be vulnerable to what is known as a SIM swap attack. SIM swapping is a social engineering method in which an attacker will call up your phone carrier, impersonating you, in attempt to re-activate your SIM card on his/her device. Once the attacker has access to your SIM card he/she now has access to your text messages which can then be used to access your online accounts. You can prevent this by using an authenticator such as Google Authenticator.

Authenticator

The use of an authenticator is the safest form of 2FA. An authenticator is installed on a seperate device and enabling it requires you input an ever changing six digit code in order to access your account. I recommend using Google Authenticator.
If a website has the option to enable an authenticator, it will give you a QR code and secret key. Use Google Authenticator to scan the QR code. The secret key consists of a random string of numbers and letters. Write this down on a seperate sheet of paper and do not store it on a digital device.
Once Google Authenticator has been enabled, every time you sign into your account, you will have to input a six-digit code that looks similar to this. If you happen to lose or damage the device you have Google Authenticator installed on, you will be locked out of your account UNLESS you have access to the secret key (which you should have written down).

Hardware Wallets

A wallet is what you store Bitcoin and cryptocurrency on. I’ll provide resources on the different type of wallets later but I want to emphasize the use of a hardware wallet (aka cold storage).
Hardware wallets are the safest way of storing cryptocurrency because it allows for your crypto to be kept offline in a physical device. After purchasing crypto via an exchange, I recommend transferring it to cold storage. The most popular hardware wallets include the Ledger Nano S, and Trezor.
Hardware wallets come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key as well as any other sensitive information in a safety deposit box.
I know this all may seem a bit manic, but it is important you take the necessary security precautions in order to ensure the safety & longevity of your cryptocurrency.

Technical Aspects of Bitcoin

TL;DR
  • Address: What you send Bitcoin to.
  • Wallet: Where you store your Bitcoin
  • Max Supply: 21 million
  • Block Time: ~10 minutes
  • Block Size: 1-2 MB
  • Block Reward: BTC reward received from mining.

What is a Bitcoin Address?

A Bitcoin address is what you send Bitcoin to. If you want to receive Bitcoin you’d give someone your Bitcoin address. Think of a Bitcoin address as an email address for money.

What is a Bitcoin Wallet?

As the title implies, a Bitcoin wallet is anything that can store Bitcoin. There are many different types of wallets including paper wallets, software wallets and hardware wallets. It is generally advised NOT to keep cryptocurrency on an exchange, as exchanges are prone to hacks (see Mt. Gox hack).
My preferred method of storing cryptocurrency is using a hardware wallet such as the Ledger Nano S or Trezor. These allow you to keep your crypto offline in physical form and as a result, much more safe from hacks. Paper wallets also allow for this but have less functionality in my opinion.
After I make crypto purchases, I transfer it to my Ledger Nano S and keep that in a safe at home. Hardware wallets also come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key in a safety deposit box.

What is Bitcoins Max Supply?

The max supply of Bitcoin is 21 million. The only way new Bitcoins can be introduced into the economy are through block rewards which are given after successfully mining a block (more on this later).

What is Bitcoins Block Time?

The average time in which blocks are created is called block time. For Bitcoin, the block time is ~10 minutes, meaning, 10 minutes is the minimum amount of time it will take for a Bitcoin transaction to be processed. Note that transactions on the Bitcoin network can take much longer depending on how congested the network is. Having to wait a few hours or even a few days in some instances for a transaction to clear is not unheard of.
Other cryptocurrencies will have different block times. For example, Ethereum has a block time of ~15 seconds.
For more information on how block time works, Prabath Siriwardena has a good block post on this subject which can be found here.

What is Bitcoins Block Size?

There is a limit to how large blocks can be. In the early days of Bitcoin, the block size was 36MB, but in 2010 this was reduced to 1 MB in order to prevent distributed denial of service attacks (DDoS), spam, and other malicious use on the blockchain. Nowadays, blocks are routinely in excess of 1MB, with the largest to date being somewhere around 2.1 MB.
There is much debate amongst the community on whether or not to increase Bitcoin’s block size limit to account for ever-increasing network demand. A larger block size would allow for more transactions to be processed. The con argument to this is that decentralization would be at risk as mining would become more centralized. As a result of this debate, on August 1, 2017, Bitcoin underwent a hard-fork and Bitcoin Cash was created which has a block size limit of 8 MB. Note that these are two completely different blockchains and sending Bitcoin to a Bitcoin Cash wallet (or vice versa) will result in a failed transaction.
Update: As of May 15th, 2018 Bitcoin Cash underwent another hard fork and the block size has increased to 32 MB.
On the topic of Bitcoin vs Bitcoin Cash and which cryptocurrency is better, I’ll let you do your own research and make that decision for yourself. It is good to know that this is a debated topic within the community and example of the politics that manifest within the space. Now if you see community members arguing about this topic, you’ll at least have a bit of background to the issue.

What is Block Reward?

Block reward is the BTC you receive after discovering a block. Blocks are discovered through a process called mining. The only way new BTC can be added to the economy is through block rewards and the block reward is halved every 210,000 blocks (approximately every 4 years). Halving events are done to limit the supply of Bitcoin. At the inception of Bitcoin, the block reward was 50BTC. At the time of writing this, the block reward is 12.5BTC. Halving events will continue to occur until the amount of new Bitcoin introduced into the economy becomes less than 1 Satoshi. This is expected to happen around the year 2,140. All 21 million Bitcoins will have been mined. Once all Bitcoins have been mined, the block reward will only consist of transaction fees.

Technical Aspects Continued

Understanding Nodes

Straight from the Bitcoin.it wiki
Any computer that connects to the Bitcoin network is called a node. Nodes that fully verify all of the rules of Bitcoin are called full nodes.
In other words, full nodes are what verify the Bitcoin blockchain and they play a crucial role in maintaining the decentralized network. Full nodes store the entirety of the blockchain and validate transactions. Anyone can participate in the Bitcoin network and run a full node. Bitcoin.org has information on how to set up a full node. Running a full node also gives you wallet capabilities and the ability to query the blockchain.
For more information on Bitcoin nodes, see Andreas Antonopoulos’s Q&A on the role of nodes.

What is a Fork?

A fork is a divergence in a blockchain. Since Bitcoin is a peer-to-peer network, there’s an overall set of rules (protocol) in which participants within the network must abide by. These rules are put in place to form network consensus. Forks occur when implementations must be made to the blockchain or if there is disagreement amongst the network on how consensus should be achieved.

Soft Fork vs Hard Fork

The difference between soft and hard forks lies in compatibility. Soft forks are backwards compatible, hard forks are not. Think of soft forks as software upgrades to the blockchain, whereas hard forks are a software upgrade that warrant a completely new blockchain.
During a soft fork, miners and nodes upgrade their software to support new consensus rules. Nodes that do not upgrade will still accept the new blockchain.
Examples of Bitcoin soft forks include:
A hard fork can be thought of as the creation of a new blockchain that X percentage of the community decides to migrate too. During a hard fork, miners and nodes upgrade their software to support new consensus rules, Nodes that do not upgrade are invalid and cannot accept the new blockchain.
Examples of Bitcoin hard forks include:
  • Bitcoin Cash
  • Bitcoin Gold
Note that these are completely different blockchains and independent from the Bitcoin blockchain. If you try to send Bitcoin to one of these blockchains, the transaction will fail.

A Case For Bitcoin in a World of Centralization

Our current financial system is centralized, which means the ledger(s) that operate within this centralized system are subjugated to control, manipulation, fraud, and many other negative aspects that come with this system. There are also pros that come with a centralized system, such as the ability to swiftly make decisions. However, at some point, the cons outweigh the pros, and change is needed. What makes Bitcoin so special as opposed to our current financial system is that Bitcoin allows for the decentralized transfer of money. Not one person owns the Bitcoin network, everybody does. Not one person controls Bitcoin, everybody does. A decentralized system in theory removes much of the baggage that comes with a centralized system. Not to say the Bitcoin network doesn’t have its problems (wink wink it does), and there’s much debate amongst the community as to how to go about solving these issues. But even tiny steps are significant steps in the world of blockchain, and I believe Bitcoin will ultimately help to democratize our financial system, whether or not you believe it is here to stay for good.

Final Conclusions

Well that was a lot of words… Anyways I hope this guide was beneficial, especially to you crypto newbies out there. You may have come into this realm not expecting there to be an abundance of information to learn about. I know I didn’t. Bitcoin is only the tip of the iceberg, but now that you have a fundamental understanding of Bitcoin, learning about other cryptocurrencies such as Litecoin, and Ethereum will come more naturally.
Feel free to ask questions below! I’m sure either the community or myself would be happy to answer your questions.
Thanks for reading!

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
  • Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with a blockchain network structure, a notion first created by Stuart Haber and W. Scott Stornetta in 1991.
  • Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
  • The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
  • With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.

1. What is Bitcoin (BTC)?

  • Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
  • Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
  • The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
  • The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
  • Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).

2. Bitcoin’s core features

For a more beginner’s introduction to Bitcoin, please visit Binance Academy’s guide to Bitcoin.

Unspent Transaction Output (UTXO) model

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.
https://preview.redd.it/t1j6anf8f3151.png?width=1601&format=png&auto=webp&s=33bd141d8f2136a6f32739c8cdc7aae2e04cbc47

Nakamoto consensus

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.

The blockchain

Block production

The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.

https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d

Block time and mining difficulty

Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.

What are orphan blocks?

In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.

3. Bitcoin’s additional features

Segregated Witness (SegWit)

Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
  3. At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID.
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.

Lightning Network

Lightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.
https://preview.redd.it/cy56icarf3151.png?width=1601&format=png&auto=webp&s=b239a63c6a87ec6cc1b18ce2cbd0355f8831c3a8
One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.

Schnorr Signature upgrade proposal

Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.
https://preview.redd.it/hjeqe4l7g3151.png?width=1601&format=png&auto=webp&s=8014fb08fe62ac4d91645499bc0c7e1c04c5d7c4
However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.
https://preview.redd.it/axg3wayag3151.png?width=1601&format=png&auto=webp&s=93d958fa6b0e623caa82ca71fe457b4daa88c71e
The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.

4. Economics and supply distribution

The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.

Binance CEO Makes Another Bullish Prediction – Bitcoin To Reach $100,000

Changpeng Zhao Also Thinks The Recession Would Soar Bitcoin’s Market Capitalization To $2 Trillion
The crypto world fell under the hits of the global economic downturn, due to the recent COVID-19 outbreak. While the stock market wiped almost 40% of its gains, many saw Bitcoin to be a safe haven asset in times of global crisis.
However, the world’s largest cryptocurrency to date failed to stand up to the beliefs of a significant portion of the crypto sector, falling to sub-$4,000 levels, before regaining some of its momentum. Despite the recent rallies, the 30% drop, leading to massive sell-offs, led to lowered trading volumes and market capitalization.
Now, amid Coronavirus outbreak and the U.S. Federal Reserve’s plans for close to $6 trillion stimulus issuance, the financial world may see vast inflation. The Federal Reserve, as well as the national banks of most of the COVID-19-affected countries, plan to print colossal amounts of cash and inject them into the economy. During the havoc, crypto bulls are stepping up their game. Some of them even predicted Bitcoin to hit $100,000 per coin.
One of the most notorious Bitcoin bulls, Binance’s CEO Changpeng Zhao, made another bullish statement on Twitter. He noted that “when speaking in trillions, a modest prediction of $2 trillion market capitalization would mean Bitcoin’s price will be $100,000 per BTC.
Zhao’s predictions come amid the U.S. Senate giving its approval to distribute $2 trillion in relief packages to U.S. citizens affected by the virus outbreak. The stimulus package is by far the most significant rescue deal in the history of the United States.
However, most of the Bitcoin bullishness comes from the long-awaited Bitcoin halving, scheduled for May. The halving process means the reward Bitcoin miners get from mining a block would be cut in half.
„Most of us agree on the fact that the moves by the U.S. Federal Reserve would drive increased inflation so that Bitcoin may become a hedge against the depreciation of the U.S. Dollar. The halving process and the current global financial situation may drive a drastic positive impact on Bitcoin, as well as on the entire crypto sector in the medium and long-term timeframes.” eToro market analyst Simon Peters stated.
Meanwhile, the crypto mining community awaits Bitcoin’s halving. The reward for mining a block would fall from 12,5 to 6.25 BTC, which cuts the new Bitcoin supply. A halving occurs once every four years, with previous events in 2012 and 2016. The ultimate goal is to reduce the mining price until Bitcoin reaches its maximum coin supply of 21 million BTC. However, Bitcoin won’t reach 21 million BTC in circulation at least for 100 years ahead.
CoinCorner’s CEO Danny Scott commented on the possible trends in front of Bitcoin, citing that “Bitcoin received a massive positive push in the months after a halvening, which now may be boosted by the current COVID-19 disease.”
“Despite the halvening, the COVID-19 crisis led to massive sell-offs for fiat cash, which caused liquidity crisis and global market drops. Even gold lost some of its momentum.” Scott concluded.

What is halving and how will it affect the crypto market?

What is halving and how will it affect the crypto market?

https://preview.redd.it/v26vq3r50rc41.png?width=1000&format=png&auto=webp&s=dcd5c313c0ea76cb05d1239c41794459e68eb275
A distinctive feature of Bitcoin and most cryptocurrencies is that their emission is limited. New coins are issued only until the last coins are mined. This approach protects digital currencies from deflation. Banks issue new bills, thereby reducing the purchasing power of money. When the maximum number of coins is reached, it will be impossible to get new ones.
If mining was carried out evenly, there would be no shortage of coins, and this factor plays a key role for the growth of the exchange rate. The halving process was programmed to ensure the coin deficit in blockchain networks.
Halving is reducing of the reward to miners for mining new blocks. Initially, for each block of Bitcoin found, miners received 50 BTC. But every few years, the reward is halved. In 2020, miners are waiting for the 4th halving of Bitcoin, after which the block reward will decrease to 6.25 BTC.
What will this mean for the crypto market? Many crypto experts and enthusiasts note that halving has a positive effect on the rate of the main cryptocurrency and the crypto market as a whole. Previously, some time before the event, Bitcoin began to grow in price and after each halving it only became more expensive.

https://preview.redd.it/ajddfdp70rc41.png?width=667&format=png&auto=webp&s=5973076f57e71ef10b5b18b32ea36eba29a425d4
The previous halving took place on July 9, 2016. As you can see on the chart, even before halving, the Bitcoin exchange rate increased from $439 to $773 per coin. Then the first cryptocurrency continued its growth after a short correction.
But there is also the negative side of halving Halving the reward for new blocks is an extremely unfavorable event for miners. If the exchange rate does not exceed $12,000 before halving, then large mining companies, in whose hands the largest computing power of the network is concentrated, will suffer huge losses. When evaluating forecasts, you should take into account the correlation of cryptocurrencies: a positive correlation indicates that with the growth of Bitcoin associated with halving, altcoin will also grow. If the correlation is negative, the process will reverse accordingly. The correlation coefficient can be found on the Plot.ly website.
Forecasters differ in their estimates, but mostly there is a positive attitude.

Bitcoin fees if BTC reaches 100k or 1 million?

Hi,
recently I've seen a couple of videos saying that it's quite realistic for BTC to reach 100 k or even a million and thy suggest also the amount you should own to be in the "1% club" or such things... this made me think about fee prices.

In the last bullrun, when BTC reached 20k, we read that fees to transact bitcoin were very expensive at around 35-50 USD. At 20k, a 50 USD fee (before exchanges implemented segwit) was about 35/20000 = 0.00175 BTC (or 0.0025 BTC for 50 USD fees).
Recently there were improvements thanks to segwit, and I see in many exchanges that fees for BTC withdrawals are set to 0.0005 BTC (see e.g. binance, kraken etc.). Situation right now:
Price 7k. Fee: 7000*0.0005 = 3.5 USD

My question is, what happens during the next bullrun, when bitcoin reaches high prices?
If the fees (in BTC) stay stable at 0.0005 BTC, this means that fees will look like this:
Price (USD) Fee (USD) Calculation
20k 10 20000*0.0005
100k 50 100000*0.0005
1 million 500 1000000*0.0005
So... if the price moons at 1 million people will still (this is the question) have to pay 0.0005 BTC to withdraw BTC from exchanges that charge a fee.
Smart people that hodl BTC in their own wallets, to save up will have to try to use less then the "recommended" 0.0005 BTC fee and use accelerators or hope that the transaction will be mined... and wait maybe days for a transaction at low fees to be mined (I tested this with "greedy/low" fees and without accelerator my test transactions were not mined within a week).

Maybe I'm too early, thinking already at such moon prices... but if this happens it's better to be ready than sorry, especially for people that hodl a little fraction of a bitcoin, say 0.001 BTC. Everybody is saying "not your keys, not your bitcon", but for such small amounts it seems to me that it's better to buy & hodl bitcoin in those exchange that pay the fees for the customer, such at bitstamp, or coinbase.

If bitcoin reaches 1 million and at that time I'll want to open a lightning channel and use a little amount of money (e.g. 100 USD worth of BTC) to fund it from an exchange like kraken, it's not gonna be worth it. I mean, 500 USD in fees to open a 100 USD channel? Probably I'm missing something, so I'm here to seek some good soul to explain.

Don't take me wrong, I love bitcoin and I hope that the price will moon. But I wonder what will happen to the fees? Will miners be happy to include transactions that pay less sats/byte in fees, considering that they will use much more electricity in the future, to mine blocks (and get less rewards, after the halving in 2020)?

Thanks for a friendly explanation, good reads that analyze this problem and think about the future are welcome too. Cheers

Bitcoin’s Record Hash Rate May Hint at Price Gains to Come

Bitcoin’s Record Hash Rate May Hint at Price Gains to Come


Article by Coindesk: Omkar Godbole
Bitcoin’s latest bout of consolidation may end up with bullish breakout, as a key metric of miner confidence has hit all-time highs.
The top cryptocurrency by market value has clocked lower daily highs and higher daily lows over the last three days and is currently trading at $10,300 on Bitstamp, little changed on a 24-hour basis.
The cryptocurrency has charted the narrowing price range amid a surge in non-price metrics including a rise in the network’s hash rate — a measure of the computing power dedicated to mining bitcoin.
The two-week average hash rate reached a record high of 85 exahashes per second (EH/s) around 19:00 UTC last Friday. Further, mining difficulty — a measure of how hard it is to create a block of transactions — also jumped to a new all-time of nearly 12 trillion.
The hash rate could be considered a barometer of miner’s confidence in the bitcoin price rally. After all, the miners would be ready to dedicate more resources for mining if they are bullish on price and would want to scale back their operations if a price slide is expected.
Hence, many observers, including the likes of Changpeng Zhao, Founder of Binance, and former Wall Street trader and journalist Max Keiser believe prices follow hash rate.

https://preview.redd.it/vapgqlijqgn31.png?width=660&format=png&auto=webp&s=f7dbc990a6f6f57cbbf16ce2bbafa193e49a8acf
Zhao tweeted on Friday that, “a rising hash rate means more miners are investing in BTC”, while few other observers stated that sellers should think twice before betting against the most secure blockchain — the higher the hash rate of a cryptocurrency network, the more expensive to 51 percent attack.
Put simply, Zhao is expecting bitcoin’s price to track the hash rate higher. It is worth noting that the market stands divided on the relationship between bitcoin’s price and hash rate.
Some observers believe the hash rate follows price and the metric’s outperformance represents overtly exuberant miners. Hence, reading the rising hash rate as a sign of an impending price rally may prove costly.
That said, the price is likely to follow the hash rate this time, as overexuberance is typically observed at market tops or near record highs. As of now, BTC is down almost $10,000 from the record high of $20,000 reached in December.
Also, the market sentiment is quite bullish with reward halving (supply cut) due in less than a year and the sustained uptick in miners’ confidence is more likely to draw fresh bids, possibly leading to a positive feedback loop.
All-in-all, the narrowing price range established over the last few days is likely to pave the way for a bullish move.

Daily and 4-hour charts


Bitcoin has charted (above left) back-to-back inside bar candlestick pattern over the last three days. The first inside bar appeared on Friday as that day’s high and low fell within Thursday’s trading range.
The second and the third inside bar candle was created on Saturday and Sunday, respectively.
Inside bars indicate consolidation and lack of volatility and often end with an explosive move on either side. A break below the first inside bar’s (Friday) low of $10,154 would imply range breakdown and could yield a stronger sell-off to levels below $9,855 (Sept. 11 low).
A break above Friday’s high of $10,458 would imply range breakout and open the doors to $10,956 (July 20 high).
The falling wedge breakout confirmed on the 4-hour chart (above right) last week is still valid. So, the probability of range breakout is high.

Coin-a-Year: Raiblocks

Howdy, folks! ♫Welcome back to the show that never ends!♫
I've decided it's high time I did a Coin-a-Year on Raiblocks. This is a special feature I do to recycle old material revisit past coins I've covered of special note a year or more later. I originally posted my Coin-a-Day feature about Raiblocks on this subreddit March 7th, 2016; it didn't get much attention then, but I have a strange feeling people might be slightly interested to see the difference now.
Below is the original report. I'll strike out what is wrong now, and add [bracketed notes] for updated commentary.
I'm no expert on the current state of Rai by any means. I'd honestly thought the coin was dead later in 2016; just didn't check back into it. And now here we are.
Bias note: I got a significant bit of Rai from the original faucet. I have sold a fraction of that this year but still have a lot of it. I'm biased both by holding it and from selling it.
Hello, y'all! I saw a comment pointing to this coin as being designed for free transactions, which is a core interest to me, so I decided to look into it a little bit and do a write-up. Enjoy!
Summary
Today's coin is Raiblocks (RAIXRB), which are designed to support free transactions and no block rewards. The coins will be initially distributed by a CAPTCHA controlled faucet with an annual halving rate.
[Faucet now closed.]
Initial creation: October 15th, 2015 [1]
Coin supply: 4.8 x 1012 rai current supply in circulation; 3.4 x 1014 rai maximum supply [2]
[XRB is the new standard base unit which was Mrai before (and still I suppose). Also, supply is distributed. So we now have about 133 million XRB as the outstanding and max supply.]
All-time high: Not yet traded as far as I know. [3]
[About $37.5 or 0.0028 per CMC max so far, about two days ago]
Current price: Not yet traded as far as I know. [3]
[Depending on the exchange and moment, somewhere around $30-35 currently or about 0.002-0.0022 BTC]
Current market cap: Not yet traded as far as I know. [3]
[Somewhere around $4 billion]
Block rate (average): Unlimited [4]
Transaction rate: ? [5]
[I'm too lazy to find this right now. Maybe someone will chime in with it in the comments.]
Transaction limit (currently): None [6]
Transaction cost: Free [7]
Rich list: ? [8]
[https://raiblocks.net/page/frontiers.php - Top 100 own ~63%]
Exchanges: None yet. [3]
[Bitgrail and Mercatox have been the two main. Kucoin just added it and Binance has it in its voting which is ending shortly.]
Processing method: Proof-of-stake [9]
[Above refers I believe to dispute resolution (double spend). There's also a minor PoW for send/receive.]
Distribution method: Faucet [10]
Community: New-born [11]
[Fairly strong and growing. Good memes. Slightly drunk on euphoria currently.]
Code/development: Active development at https://github.com/clemahieu/raiblocks
Leadership: Colin LeMahieu
Innovation or special feature: Protocol designed without a limited throughput or block rate, as well as not supporting block rewards nor transaction fees.
Description
Raiblocks is, as far as I know, the first cryptocurrency designed from its start to not support any block reward or transaction fee. In addition, it has no block size or rate limit. Further, all coins will be initially distributed through a captcha-controlled faucet on the main site. It's a bold attempt, going against the conventional wisdom of what is possible.
Edit: I should mention a couple things. First, there is a PoW attached to transactions as an anti-spam defense. This PoW can be attached by the recipient rather than the sender as well, which means that large automated sends could be done without the PoW if needed and the recipient could attach that.
Also, the natural question coming from how all the rest of the cryptocurrencies work is "how does it work without an incentive to run a node?" The idea presented in the whitepaper is basically that operating a cryptocurrency has a lot of expenses, and most of them are paid "out-of-band", so why not have funding nodes be that way too? It leaves it open to whatever other incentives there may be, of which the most obvious are first: that there are only full nodes so far, so if one wants to use the coin, then one is going to run a node. More long-term, even after SPV, presumably large holders might choose to operate one regardless. Someday, if merchants accept it, they would presumably run one. And enthusiasts. It sounds very tenuous, and this is why this is such an audacious attempt in my opinion.
After six months running, the number I heard for the blockchain size was about 20 MB, which is insanely small, but the coin has gotten so little attention that I suspect there hasn't been significant load yet. I'm very curious to see how it will perform under load. I think its design actually makes it more efficient when there aren't transactions, because nothing is added to the blockchain (actually termed block lattice here, but using blockchain generically to refer to any cryptocurrency's core data), unlike in the conventional / Bitcoin model where blocks are being generated whether or not there are transactions in them. Of course that doesn't matter much when there are tons of transactions, as on Bitcoin currently, but, for instance, in Nyancoin, we accumulate tons of empty blocks all the time, where Raiblocks would just wait for more transactions. However, again, under load perhaps it could start growing "too quickly" by some metric, or eventually reach the point where it starts losing users because of the requirements of running a full node.
I think it will be very interesting to see how this turns out in practice.
[And it's certainly going to be interesting to see how it goes. So far, it's still working. Which is better than I'd hoped or expected.]
Community
The coin is relatively young but even for a young coin it's not a huge community. But there is clear discussion and interest both on BCT and on their Google Group. It looks like a healthy start to me.
[As per my comment above: Fairly strong and growing. Good memes. Slightly drunk on euphoria currently. Seems well-intentioned generally: looking to try to have some caution mixed in and putting up a bug bounty and that sort of thing. Still has a little bit of some of the common negative characteristics in crypto communities but this may be due to growth from outside communities overwhelming the local culture temporarily more than anything.]
Footnotes
[1] https://bitcointalk.org/index.php?topic=1208830.0 - Initial announcement, didn't get much attention apparently. Also, this thread mentions a built-in block-explorer with a rich list. I don't have a working client to access this at the moment but that's pretty cool.
[2] There are 2128 total units, and a rai is 1024 total units, so total supply should be about 3.4 x 1014. https://github.com/clemahieu/raiblocks/wiki/Distribution-and-Mining Distribution has been going since about November 2015, so I would expect about one-third of the initial 50% to be distributed. The block explorer seems pretty primitive; it just takes a hash. No overall stats. So I'll use that one-third of the initial 50% estimate. So about 5.7 x 1013. Note by comparison that the faucet gives 108 coins at a time currently.
Actually, this comment puts the amount of rai in circulation as 4,763,023...that can't be right, that many Mrai I think? Yeah, 1030 stated as divider there. So 4.8 x 1012 rai in current circulation.
[3] https://groups.google.com/forum/#!topic/raiblocks/PSbX_onjLfU - This topic discusses it a bit. Also comments from meor in this thread
However, I have also paid 100 NYAN for 100 Mrai. This is basically a test transaction, but 1 NYAN for 1 Mrai (106 rai) would imply a marketcap of 4.8 million NYAN, or about 0.34 BTC in current circulation. I had initially thought this was higher before recalculating with the actual amount circulating as per [2]; may also have screwed up the math initially or here.
[4] https://docs.google.com/document/d/13s6BKzRq9oD5Me55JBRzR7BdvjJ44QKqPu2lf-JsAlU/edit - whitepaper ; each transaction could be thought of as its own block if I am grokking this right. It goes through as fast as the network can handle it. There is no fixed interval or period.
[5] I believe https://raiblocks.net/#/block-explorer is the only block explorer so far and it only supports entering a hash, so I don't have a way to determine the transactions in the last 24 hours.
[6] https://docs.google.com/document/d/13s6BKzRq9oD5Me55JBRzR7BdvjJ44QKqPu2lf-JsAlU/edit - The protocol is designed without a limit if I understand correctly.
[7] https://docs.google.com/document/d/13s6BKzRq9oD5Me55JBRzR7BdvjJ44QKqPu2lf-JsAlU/edit - The protocol is designed without transaction fees or block rewards.
[8] As per [5], the block explorer does not support this. There area couple addresses known to be the initial generation which will go into the faucet, but beyond that I don't know the distribution. There's supposed to be a rich list available in the built-in explorer, but I was unable to get a client running on my out-of-date systems (32-bit Windows (64-bit Windows client only), and CentOS 6 (glibc too old)).
[9] In general all full nodes are maintaining their own copies of all the information, but as I understand it the dispute resolution is based on voting by ownership of rai.
[10] All rai will be distributed through https://raiblocks.net/#/start as per https://github.com/clemahieu/raiblocks/wiki/Distribution-and-Mining
[11] There's been some discussion on BCT as well as on the google group: https://groups.google.com/forum/#!forum/raiblocks ; there's a new subreddit /raiblocks, but it's still set on private for some reason at the time of writing this footnote (just wrote a comment to meor noting this).

Disclosure, disclaimer
Disclosure: I have made an agreement to purchase 100 Mrai and have paid 100 NYAN for this. I have no other financial interest in Raiblocks currently, but I do intend to get a client ultimately (my current OSes are incompatible from being too old (one is 32-bit Windows; other CentOS 6 with too old glibc)) and get free coins from the faucet and play with this more.

Up next:
Tell me what coin to write about next by sponsoring an article! A sponsored article would likely have more discussion than I did here, and less than my Coin-a-Year report on Nyancoin.
Edit: /RaiBlocks is now public! New subreddit, but hopefully it'll build up a bit over time. :-)
Edit 2: Added more than the stub discussion discussion section I'd initially done.
Okay, so those last links are generally outdated and old information and I stopped commenting through all that. Go to https://raiblocks.net/ and/or /raiblocks if you want to learn more. :-)
Again, I'm heavily biased from having gotten incredibly fortunate from this price rise and having been fortunate enough to have been introduced to the coin early on. I'm not giving trading advice. The market is crazy but I have no idea if it'll go up, down, sideways, or loop-de-loop.
Have fun and stay safe!

The Greater Fool's Theory: Crypto Edition

There is a big cognitive dissonance within the crypto community. The dream of decentralization and censorship resistance is dominated by big centralized exchanges centralized empires like Binance and Coinbase.
Speculation still drives the market and fuels the continued growth of centralized exchanges. One of the leading factors fueling the revenue stream of exchanges is new coins, namely ICOs and in future STOs. ICOs became nothing more than a way of Flipping Tokens. Most ICOs used and continue to used Proof of Greater Fool to push forward their blockchain.
People invest in something that they know is probably worthless and extremely overpriced, hoping that they can sell that worthless overpriced digital token to a "Greater Fool". In the end, all ICO investors are fools because even if Fool #1 manages to Flip the token at 3x the price he bought it at, he is still the fool compared to the ''ICO that now holds millions** collected by all the #1 fools.
Essentially ICOs that list on exchanges right away that have nothing to offer and no product are basically Ponzi schemes, with ICO team at the top, ICO Buyers second Layer and people on the exchange at the bottom of the pyramid.
The IEO (Initial Exchange Offering) is a natural evolution of this Ponzi scheme: Now with ICO and Exchanges working together to pump up the price, being able to freely manipulate the price of the token and print free money. As Cryptocurrencies are a totally unregulated market they are pretty much free to do whatever they want.
Cryptocurrency exchanges basically became empires fueled by greed, trading fees, listing fees, and so much more. These empires have no interest in changing the system, similar to how banks do not want to give away power.
It is expected of anyone in power to be very corrupt in a totally uncontrolled market.

BUIDL VS Initial Exchange Offerings

In 2019, for the first time in 3 years, projects that focused on tech, product, and business development came out of the darkness.
Most people pretended to work to look good to raise money, however, some actually worked to solve problems. 2019 was also the year that we started to see Initial Exchange Offerings. ICOs conducted on exchanges compared to publicly.
The original purpose of ICOs was to take away the monopoly of fundraising away from stock exchanges and brokerage firms. An IEO is well explained in that scene of Wolf of Wall Street, when they opened an IPO for Steve Madden shoes. Remember when a centralized entity is responsible for issuing a new stock? It probably has a vast interest in pumping that price, but is it legal in the traditional financial space?
ICOs that are actually working hard to build their product also understand that in order for their projects to become successful they need to become decentralized. They need to get their tokens in as many hands as possible. Of course, the person that is attached to that hand should also bring value to the project.
The best example of the power of useful decentralization is Bitcoin. Bitcoin has a pretty old tech, had a few bugs in their source code, is super slow, but yet it has by far the best community and strongest social consensus. Hashrate doesn't mean much, after all, Bitcoin Cash had a bigger hash rate for a brief while, but it was the social consensus of the mining community that decided not to implement the new changes introduced by Rodger and Bitmain. Now BCH is less than 96% of the market Cap it used to be.
The value of cryptocurrencies is defined by nothing more than censorship resistance, game theory, and token holders. In the long term, these three factors will be decisive determining which coin will have the biggest market cap. Bitcoin has by far the most censorship resistance, probably one of the best game theories and by far the best community.
The value of a coin is pretty much all about: how hard it is to change the information saved on the block * (sum of all useful skills and influence amongst all token holders) that can be leveraged by game theory within the ecosystem.

Best case vs Worst Case outcome for an ICO

An ICO that is used for its actual purpose and not as a vehicle to facilitate scamming, can be seen as the big bang of any new blockchain ecosystem. Successful ICOs understand that they need to act like economies, not companies. Usually, economies filled with smart people that can utilize their skills to push their ecosystem that is also run by the good government (good game theory) do very well, compared to economies that have a very small set of inhabitants that can bring economic value for influence and skill sets.
The optimal scenario for an ICO would be if the tokens were magically distributed among the best developers, business integrators, influencers, politicians and basically anybody that would be willing and capable of bringing value to the new blockchain ecosystem.
Bitcoin’s mechanism to achieve this magical community was via mining and its 4-year reward halving cycle. It takes a great deal of passion and technical skills to start mining. Also, the low token price during the first few years motivated the best developers, who are also deeply interested in the technology, to jump onboard and help on its development efforts. This also allowed them to acquire a lot of tokens in the process.
The 4 year Bitcoin Pump and Dumps enable very smart individuals to join the bitcoin ecosystem every 4 years and accumulate at low prices. Regulators love crypto once they’ve also bought a bag.
Therefore the best outcome is the magical distribution of tokens to all the best developers, business integrators, influencers, politicians and basically anybody that would be willing and able to help that new blockchain ecosystem. The worst case would be an ICO whose tokens holders are mostly speculators, also known as an initial Exchange offering.

ICO DOG offers a different path: Social Mining

We have been very busy for the past few months to build an IDK (ICO Development Kit) for the cryptocurrency ecosystem.
It is an off chain - onchain hybrid solution that any project can plug into their project to assist them with all problems they could potentially face and helps them in the long run to become a decentralized autonomous system. We called it Social Mining, proof of engagement. A certain percentage of the token supply is dedicated for social mining. Any ICO or Post ICO project can plugin our solution to boost their community and to help them become more decentralized.
We have been testing the system now for about 6 weeks and the results are already overwhelming for our first client LTO Network. After the first 6 months, LTO network now has 8 different language channels, community marketing team, over 50 mainnet nodes, community development team, and community produced merchandise shop. The platform is in every sense the opposite of an Initial Exchange offering.
The best performing ICO in the past 12 Months was raised via an IEO on Binance 2nd best performing ICO was raised via our IDK and proof of engagement
You can find a very good in-depth comparison of the two projects here: https://cryptodiffer.com/news/buid-the-meme-that-thrives-in-todays-bearmarket-by-steven-price/

[uncensored-r/CryptoCurrency] Coin-a-Year: Raiblocks

The following post by coinaday is being replicated because some comments within the post(but not the post itself) have been openly removed.
The original post can be found(in censored form) at this link:

The original post's content was as follows:
Howdy, folks! ?Welcome back to the show that never ends!?
I've decided it's high time I did a Coin-a-Year on Raiblocks. This is a special feature I do to recycle old material revisit past coins I've covered of special note a year or more later. I originally posted my Coin-a-Day feature about Raiblocks on this subreddit March 7th, 2016; it didn't get much attention then, but I have a strange feeling people might be slightly interested to see the difference now.
Below is the original report. I'll strike out what is wrong now, and add [bracketed notes] for updated commentary.
I'm no expert on the current state of Rai by any means. I'd honestly thought the coin was dead later in 2016; just didn't check back into it. And now here we are.
Bias note: I got a significant bit of Rai from the original faucet. I have sold a fraction of that this year but still have a lot of it. I'm biased both by holding it and from selling it.
Hello, y'all! I saw a comment pointing to this coin as being designed for free transactions, which is a core interest to me, so I decided to look into it a little bit and do a write-up. Enjoy!
Summary
Today's coin is Raiblocks (RAIXRB), which are designed to support free transactions and no block rewards. The coins will be initially distributed by a CAPTCHA controlled faucet with an annual halving rate.
[Faucet now closed.]
Initial creation: October 15th, 2015 [1]
Coin supply: 4.8 x 1012 rai current supply in circulation; 3.4 x 1014 rai maximum supply [2]
[XRB is the new standard base unit which was Mrai before (and still I suppose). Also, supply is distributed. So we now have about 133 million XRB as the outstanding and max supply.]
All-time high: Not yet traded as far as I know. [3]
[About $37.5 or 0.0028 per CMC max so far, about two days ago]
Current price: Not yet traded as far as I know. [3]
[Depending on the exchange and moment, somewhere around $30-35 currently or about 0.002-0.0022 BTC]
Current market cap: Not yet traded as far as I know. [3]
[Somewhere around $4 billion]
Block rate (average): Unlimited [4]
Transaction rate: ? [5]
[I'm too lazy to find this right now. Maybe someone will chime in with it in the comments.]
Transaction limit (currently): None [6]
Transaction cost: Free [7]
Rich list: ? [8]
[https://raiblocks.net/page/frontiers.php - Top 100 own ~63%]
Exchanges: None yet. [3]
[Bitgrail and Mercatox have been the two main. Kucoin just added it and Binance has it in its voting which is ending shortly.]
Processing method: Proof-of-stake [9]
[Above refers I believe to dispute resolution (double spend). There's also a minor PoW for send/receive.]
Distribution method: Faucet [10]
Community: New-born [11]
[Fairly strong and growing. Good memes. Slightly drunk on euphoria currently.]
Code/development: Active development at https://github.com/clemahieu/raiblocks
Leadership: Colin LeMahieu
Innovation or special feature: Protocol designed without a limited throughput or block rate, as well as not supporting block rewards nor transaction fees.
Description
Raiblocks is, as far as I know, the first cryptocurrency designed from its start to not support any block reward or transaction fee. In addition, it has no block size or rate limit. Further, all coins will be initially distributed through a captcha-controlled faucet on the main site. It's a bold attempt, going against the conventional wisdom of what is possible.
Edit: I should mention a couple things. First, there is a PoW attached to transactions as an anti-spam defense. This PoW can be attached by the recipient rather than the sender as well, which means that large automated sends could be done without the PoW if needed and the recipient could attach that.
Also, the natural question coming from how all the rest of the cryptocurrencies work is "how does it work without an incentive to run a node?" The idea presented in the whitepaper is basically that operating a cryptocurrency has a lot of expenses, and most of them are paid "out-of-band", so why not have funding nodes be that way too? It leaves it open to whatever other incentives there may be, of which the most obvious are first: that there are only full nodes so far, so if one wants to use the coin, then one is going to run a node. More long-term, even after SPV, presumably large holders might choose to operate one regardless. Someday, if merchants accept it, they would presumably run one. And enthusiasts. It sounds very tenuous, and this is why this is such an audacious attempt in my opinion.
After six months running, the number I heard for the blockchain size was about 20 MB, which is insanely small, but the coin has gotten so little attention that I suspect there hasn't been significant load yet. I'm very curious to see how it will perform under load. I think its design actually makes it more efficient when there aren't transactions, because nothing is added to the blockchain (actually termed block lattice here, but using blockchain generically to refer to any cryptocurrency's core data), unlike in the conventional / Bitcoin model where blocks are being generated whether or not there are transactions in them. Of course that doesn't matter much when there are tons of transactions, as on Bitcoin currently, but, for instance, in Nyancoin, we accumulate tons of empty blocks all the time, where Raiblocks would just wait for more transactions. However, again, under load perhaps it could start growing "too quickly" by some metric, or eventually reach the point where it starts losing users because of the requirements of running a full node.
I think it will be very interesting to see how this turns out in practice.
[And it's certainly going to be interesting to see how it goes. So far, it's still working. Which is better than I'd hoped or expected.]
Community
The coin is relatively young but even for a young coin it's not a huge community. But there is clear discussion and interest both on BCT and on their Google Group. It looks like a healthy start to me.
[As per my comment above: Fairly strong and growing. Good memes. Slightly drunk on euphoria currently. Seems well-intentioned generally: looking to try to have some caution mixed in and putting up a bug bounty and that sort of thing. Still has a little bit of some of the common negative characteristics in crypto communities but this may be due to growth from outside communities overwhelming the local culture temporarily more than anything.]
Footnotes
[1] https://bitcointalk.org/index.php?topic=1208830.0 - Initial announcement, didn't get much attention apparently. Also, this thread mentions a built-in block-explorer with a rich list. I don't have a working client to access this at the moment but that's pretty cool.
[2] There are 2128 total units, and a rai is 1024 total units, so total supply should be about 3.4 x 1014. https://github.com/clemahieu/raiblocks/wiki/Distribution-and-Mining Distribution has been going since about November 2015, so I would expect about one-third of the initial 50% to be distributed. The block explorer seems pretty primitive; it just takes a hash. No overall stats. So I'll use that one-third of the initial 50% estimate. So about 5.7 x 1013. Note by comparison that the faucet gives 108 coins at a time currently.
Actually, this comment puts the amount of rai in circulation as 4,763,023...that can't be right, that many Mrai I think? Yeah, 1030 stated as divider there. So 4.8 x 1012 rai in current circulation.
[3] https://groups.google.com/forum/#!topic/raiblocks/PSbX_onjLfU - This topic discusses it a bit. Also comments from meor in this thread
However, I have also paid 100 NYAN for 100 Mrai. This is basically a test transaction, but 1 NYAN for 1 Mrai (106 rai) would imply a marketcap of 4.8 million NYAN, or about 0.34 BTC in current circulation. I had initially thought this was higher before recalculating with the actual amount circulating as per [2]; may also have screwed up the math initially or here.
[4] https://docs.google.com/document/d/13s6BKzRq9oD5Me55JBRzR7BdvjJ44QKqPu2lf-JsAlU/edit - whitepaper ; each transaction could be thought of as its own block if I am grokking this right. It goes through as fast as the network can handle it. There is no fixed interval or period.
[5] I believe https://raiblocks.net/#/block-explorer is the only block explorer so far and it only supports entering a hash, so I don't have a way to determine the transactions in the last 24 hours.
