== The Blockchain ==
 +
 
 +
Cryptocurrency hinges on The Blockchain.  It would not exist without it.
 +
 
 +
'''Short Explanation'''
 +
 +
“The blockchain” is a decentralized, immutable digital ledger that records transactions across a network, ensuring transparency and security in cryptocurrencies like Bitcoin.
 +
 
 +
'''Long Explanation'''
 +
 
 +
The cryptocurrency blockchain is a revolutionary technology that underpins digital currencies like Bitcoin. It functions as a decentralized, distributed ledger, recording and verifying transactions across a network of computers. Unlike traditional financial systems, there's no central authority; instead, a consensus mechanism ensures trust among participants.
 +
 
 +
Each block in the chain contains a batch of transactions, and once confirmed, it becomes immutable. This immutability ensures security and prevents tampering, making the blockchain highly transparent and resistant to fraud. Participants, called nodes, maintain copies of the entire blockchain, adding new blocks through complex cryptographic processes, like mining.
 +
 
 +
This innovation has far-reaching implications, extending beyond finance to supply chain management, voting systems, and more, due to its potential for secure, transparent record-keeping in various fields.
 +
 
 +
'''Blockchain Difficulty'''
 +
 
 +
This is one of the most important parts of mining to understand. ‘Difficulty’ is how the puzzle adjusts in order to maintain a level playing field and network stability. It takes a lot of computing power to create ‘hashes’ in order to try to solve the puzzle.
 +
 
 +
But if millions of people are all trying to solve the puzzle with lots of computing power, then the puzzle will get solved more quickly and more frequently, right?
 +
 
 +
Wrong. The network difficulty adjusts itself to maintain more or less the same block time (eg. ~10 minutes for Bitcoin), meaning more or less the same probability of validating a block. The more miners are mining (trying to solve the puzzle with their computer power) the harder the difficulty gets. When this happens, miners need even more computing power to solve the puzzle, so those who don’t have enough (older machines for example) either upgrade their hardware, buy more hardware, or stop mining (since the extra cost of hardware + electricity makes mining for them unprofitable or less profitable during the time difficulty is high).
 +
 
 +
So what happens then? Doesn’t that mean it’s not profitable for anyone?
 +
 
 +
Well then many miners stop mining since they are not profitable, but when miners start to drop off the network, the difficulty adjusts downwards (easier) and mining becomes more profitable again (less hashpower needed to solve the puzzle during when difficulty is easy, since less computer power is needed, resulting in lower operating cost), and the cycle repeats.
 +
 
 +
=== How can I safely delete the blockchain on my Bitcoin Node and start a sync again? ===
 +
 
 +
Q - I have bitcoind installed and I'd like to free up space by deleting the blockchain from my .bitcoin directory. What set of files and directories should I delete such that the next time I start bitcoind it will recover gracefully by downloading the blockchain again?
 +
 
 +
A - Delete the "blocks" and "chainstate" directories.

=== Recurring Buys ===
 +
 +
Recurring buys are repeated, automatic purchases of cryptocurrency.  By using ''dollar-cost-averaging'' (DCA) — investing a fixed amount of cash at regular time intervals, used commonly by investors — investing can be less risky.  It is a good way of avoiding price fluctuation.  Recurring buys use DCA to automatically carry out trades.

'''What Is a Crypto Trading Bot?'''
 +
 +
A crypto trading bot is a computer program that uses artificial intelligence and advanced algorithms to automate the buying and selling of cryptocurrencies. Acting as a virtual assistant, these bots analyze vast amounts of market data, identify patterns, and execute trades in the crypto market accordingly. They can simplify the trading process and provide a competitive edge by leveraging real-time and historical market data.
 +
 +
Much like the crypto market that never sleeps, crypto trading bots can operate 24/7, taking advantage of market opportunities even when you cannot actively monitor the market. By automating trading actions, these bots aim to optimize trading strategies, improve efficiency, and potentially increase profits.
 +
 +
'''How Do Trading Bots Work?'''
 +
 +
There are two kinds of crypto bots: one that needs to connect to cryptocurrency exchanges like KuCoin, where they can access real-time and historical market data, and the other that is offered directly by crypto exchanges on their platforms like KuCoin’s trading bots, which require no technical expertise to configure. By setting predefined parameters and trading strategies, you can configure your bots to execute trades automatically when specific market conditions are met.
 +
 +
https://www.kucoin.com/learn/trading/what-are-crypto-trading-bots
 +
 +
'''What are the types of Crypto Trading Bot?'''
 +
 +
''Spot Grid'' - Spot grid trading bot is particularly effective in ranging crypto market conditions. It thrives when the prices of cryptocurrencies move within a certain range, as the grid structure enables users to profit from the recurring price oscillations that are characteristic of such market conditions. By intelligently placing buy and sell orders within this range, the KuCoin Spot Grid trading bot excels in harnessing price movements and market trends, making it a valuable tool for traders seeking to navigate and capitalize on a range-bound cryptocurrency market.
 +
 +
''Martingale'' - KuCoin’s Martingale trading bot implements a high-risk, high-reward strategy. It increases the trade size after a losing trade, aiming to recover losses with larger subsequent trades. This strategy requires careful risk management to prevent significant loss. The KuCoin Martingale trading bot automates the Martingale strategy, allowing you to capitalize on the volatility of crypto markets. The bot buys more when prices fall and sells when prices rise, effectively betting on the reversal of a downtrend. It is best suited for traders who are willing to take calculated risks and believe in their chosen crypto asset's potential to recover from lows. The bot operates 24/7, adjusting its trading volumes based on price movements, and is free to use, with the only charges being transaction costs incurred during the buying and selling of cryptos.

'''How to withdraw GBP from Binance using P2P'''
 +
 +
DO THIS ON YOUR MOBILE PHONE APP
 +
 +
This is a way to move your money from Binance to an external fiat bank account.  It is quite complex but it is '''safe''' because Binance guides you through the process and you do not release you crypto ''until you confirm you have received your fiat to your bank account''.
 +
 +
# Convert your wallet balance to '''USDT'''
 +
# Transfer the amount of USDT you want to withdraw to your Funding account - Assets > Spot > USDT > Transfer > '''Funding'''
 +
# Home > P2P  or  Icon top left > More Services > Trade > '''P2P'''
 +
# Make sure the currency to want to use is '''GBP''' in the top right next to the horizontal arrows icon
 +
# Click on the '''Sell''' tab and make sure USDT is selected
 +
# This will show you all the '''peers''' or 'buyers' for your crypto
 +
# Click on '''Amount''' to narrow the filter by £x amount - e.g. £10
 +
# Choose the peer that has the highest amount of '''trades''', completion ratio and 100% feedback
 +
# Click on '''Sell''' button and choose 'By Crypto'
 +
# Select the '''Payment Method''' and Add Bank Account details (you will notice that the ''Sort Code'' is missing)
 +
# Choose the '''amount''' of USDT to sell and click on '''Sell USDT'''
 +
# Now it will show '''Waiting for Buyer's Payment'''
 +
# Keep an eye on the yellow '''chat''' icon for a message from the buyer
 +
# When a message arrives, click on the chat icon and type in your bank's '''Sort Code''' when asked
 +
# Keep '''watching''' for any other messages from the buyer
 +
# Eventually (this took 30 minutes for NatWest) you will see a '''message from Coinbase''' confirming that the £GBP has been sent to your bank account
 +
# Switch to your '''bank app and check''' that the £GBP have arrived from the same name as shown on Binance P2P
 +
# When you are happy, go back to the Binance app and click '''Payment Received''' and confirm twice
 +
# Leave some positive '''feedback''' for the trader and ''that's it!''
 +
 +
== Staking ==
 +
 +
Staking is a process by which individuals lock their cryptocurrency (their "stake") to support the security and operation of a blockchain network. When someone stakes their coins, they are essentially helping to secure the chain and validate transactions on the blockchain.
 +
 +
Staking is only possible on blockchains such as Ethereum and Cardano based on a proof-of-stake (PoS) consensus mechanism. PoS differs from the proof-of-work (PoW) used in cryptocurrencies such as Bitcoin, where miners use computing power to validate transactions. Staking coins makes users' holdings less liquid because the coins are tied up in the staking process.
 +
 +
Individuals can usually still access their staked coins but may only be able to use them for other purposes once they are no longer staked. You can unstake your crypto at any time, and your crypto is always yours.
 +
 +
Example rates ...
 +
 +
* Solana = 4.35%
 +
* Ethereum = 3.29%
 +
* Cardano = 2.00%

 +
 +
== Stablecoins ==
 +
 +
Stablecoins are tokens pegged to an external asset, such as gold or the U.S. dollar, which ensures price stability. These coins are usually backed by the external asset, commonly USD, minimizing risk. Nonetheless, some stablecoins are collateralized by other cryptocurrencies, which elevates the risk factor. Stablecoins are generally less volatile. For instance, USDC remains fixed at $1 and is supported by numerous financial institutions. In a highly unstable market, stablecoins offer stability by being collateralized.
 +
 +
* US Dollar Coin (USDC) = 4.60%
 +
 +
== Wallets ==
 +
 +
''What is a crypto wallet?''
 +
 +
Crypto wallets allow you to store, send, and receive cryptocurrencies.
 +
 +
Wallets are usually either hot, cold, or centralized:
 +
 +
* '''Hot wallets''' connect to the internet and are usually easy to use
 +
* '''Cold wallets''' do not connect to the internet and offer the best security
 +
* '''Centralized wallets''', such as exchanges, are controlled by third parties
 +
When using a crypto wallet, the crypto is not stored in the wallet but on the blockchain. Crypto wallets use your secret recovery phrase to access and interact with your funds on the blockchain.
 +
 +
''How do Crypto Wallets work?''
 +
 +
The beauty of a crypto wallet is down to the fact that it does not store any actual money on it.  When you create a crypto wallet, the software (like those listed below) generates a key from a 12 or 24 word 'seed phrase' and embeds this key in the blockchain - so it knows what the wallet is for and what it contains.  There is NO name or email address or password involved.  This is constantly being verified IN the blockchain and updated to match what you have in your wallet.  Which means, you can install ANY crypto wallet software, import your unique 12 word key and your balance will be shown.
 +
 +
=== Seed Phrase Words ===
 +
 +
These words are chosen from a total of [https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt 2048 recovery words] defined in the [https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki BIP39 standard].
 +
 +
This MUST be written down, or '''etched in Steel'''.  No seriously, really etched in [https://cryptolisty.com/hardware-wallets/best-crypto-metal-plates-for-recovery-seed-key-and-wallet-backups/ actual steel] - because this is fireproof.  Then, this must be kept in a VERY safe place - given to a relative.
 +
 +
This is your cryptocurrency - those 12 words are the key to your money.
 +
 +
It's as simple and as paranoid as that.

=== Lightning ===
 +
 +
The Lightning Network is designed to make bitcoin transactions as fast and cheap as possible. It is part of a newer class of crypto technologies known as "layer 2" blockchains, which you can think of as being a little like HOV lanes on highways. By offloading some transaction "traffic" to the Lightning Network's "layer 2" blockchain, the core Bitcoin blockchain ("layer 1") can move faster.

 +
What Is A Full Node?
 +
 +
A full node is a program that fully validates transactions and blocks. Almost all full nodes also help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes.
 +
 +
Most full nodes also serve lightweight clients by allowing them to transmit their transactions to the network and by notifying them when a transaction affects their wallet. If not enough nodes perform this function, clients won’t be able to connect through the peer-to-peer network—they’ll have to use centralized services instead.
 +
 +
Many people and organizations volunteer to run full nodes using spare computing and bandwidth resources—but more volunteers are needed to allow Bitcoin to continue to grow.

== Mining ==
 +
 +
'''What is Bitcoin Mining?'''
 +
 +
Bitcoin mining is the process of adding new transactions to the blockchain, a public ledger of all Bitcoin transactions. This is done by using powerful computers to solve complex mathematical equations that verify the authenticity of the transactions and add them to the blockchain. Miners are rewarded with newly created bitcoins for their efforts, known as a "block".
 +
 +
'''What is Cryptocurrency Mining?'''
 +
 +
Cryptocurrency mining is the process of validating transactions and adding them to a blockchain by solving complex mathematical puzzles, typically done using powerful computers to earn rewards.
 +
 +
Mining is the process that Bitcoin and several other cryptocurrencies use to generate new coins and verify new transactions.  It involves vast, decentralized networks of computers around the world that verify and secure blockchains - the virtual ledgers that document cryptocurrency transactions.
 +
 +
The more powerful your computer, the more "hash rate" it has and can contribute a higher percentage of solving the puzzle and gain a higher reward.
 +
 +
Crypto mining is a calculation-intensive, puzzle-solving-like computation process that requires high processing power along with high electricity consumption. The miner who first solves the puzzle gets to place the next block on the blockchain and claim the rewards. Rewards include the miner becoming the owner of the newly released bitcoin, or getting fees linked to the transactions performed in the block.
 +
 +
At the earliest days of the mining, any processor or GPU had the sufficient power required for finding many solutions per day and getting a reward for the detected block.
 +
 +
With an increase of the interest in cryptocurrencies, the difficulty level of the "puzzles" also increased, and a standalone PC could not find many solutions anymore.
 +
 +
Difficulty level was rising because the reward for the newfound block was growing as well as its equivalent in value. That was the time when miners decided to unite their efforts and create the mining pools.
 +
 +
Therefore, even weak devices that are working simultaneously on solving the same "puzzle" have a chance to find its solution which would enable miners to create a new block.
 +
 +
Mining pools get solutions from all the connected miners, and if one of those numerous solutions appears to be a proper one, the pool gets a reward for the created block. This reward is shared proportionally to the efforts applied by the miners and forwarded to their wallets.
 +
 +
Farm > Rig > Worker
 +
 +
The miner, or worker, can be either CPU, GPU or ASIC based.
 +
 +
* CPU = Central Processing Unit
 +
* GPU = Graphics Processing Unit
 +
* ASIC = Application Specific Integrated Circuit
 +
 +
Today, there are thousands of dedicated farms around the world running millions of rigs.
 +
 +
'''How Many Bitcoins Are There?'''
 +
 +
* 19,489,350 = Total BTC in Existence
 +
* 1,510,650 = Bitcoins Left to Be Mined
 +
* 92.806% = Percentage of Bitcoins Issued
 +
* 900 = New Bitcoins per Day
 +
 +
=== Hash Rate ===
 +
 +
'''How Is The Hash Rate Measured & its Unit?'''
 +
 +
Hash rate is a unit measured in hashes per second or [h/s] and here are some usual denominations used to refer it.
 +
 +
'''Hash rate denominations'''
 +
 +
1 kH/s is 1,000 (one thousand) hashes per second - "''kilohash''".
 +
1 MH/s is 1,000,000 (one million) hashes per second - "''megahash''".
 +
1 GH/s is 1,000,000,000 (one billion) hashes per second - "''gigahash''".
 +
1 TH/s is 1,000,000,000,000 (one trillion) hashes per second - "''terahash''".
 +
1 PH/s is 1,000,000,000,000,000 (one quadrillion) hashes per second - "''petahash''".
 +
1 EH/s is 1,000,000,000,000,000,000 (one quintillion) hashes per second - "''extahash''".

=== Hard Drive Mining ===
 +
 +
What Is Hard Drive Mining?
 +
 +
Hard drive mining is a way of generating cryptocurrency using the storage space of hard disk drives. HDD miners do not require graphics processing units (GPUs) or ASIC miners, like in traditional mining farms, to produce new blocks in the distributed ledger. Instead, this method uses a set of hard disk drives and unused storage space, also known as proof of capacity.
 +
 +
Practically any device with loads of storage space can be used in HDD mining, as it needs less computational power than the Proof of Work, thus using less energy in the long term. New data blocks are generated when miners use their hard disks in the distributed ledger and, accordingly, get rewarded.

==== Chia ====
 +
 +
[https://www.chia.net/ Chia] is a cryptocurrency and blockchain with smart transaction capabilities. It was designed from the ground up to make cryptocurrency easier to use (and harder to lose) than cash.
 +
 +
The 'Proof of Space and Time' is the only Nakamoto consensus algorithm since Proof of Work, while also having a much lower energy consumption. Part of Chia's vision involves improving the carbon footprint of the blockchain industry.

===== Chia Farming =====
 +
 +
[https://xch.farm/basics/ CHIA FARMING BASICS]
 +
 +
Chia plotting and farming can seem daunting at first, but it's a relatively straightforward process:
 +
 +
# Obtain hardware
 +
# Install Chia
 +
# Run and configure Chia
 +
# Create a plot
 +
# Start farming
 +
 +
'''Pools and Payouts'''
 +
 +
When you join a pool, you are given a 'payout address' which is generated from your main 'Chia Wallet'.
 +
 +
When you farm to a pool, you gradually build up mojo and when the minimum amount of mojo has been farmed (or mined) then the Pool will payout to your address.
 +
 +
You then view your wallet balance and can send your mojos to an external exchange address.
 +
 +
To make this process quicker, you can change your Pool's payout address to that external exchange address.
 +
 +
Here are the cli commands to do all of this in the Linux terminal:-

 +
1. Make sure your database in fully synced ...

=== Mobile Phone Mining ===
 +
 +
Mobile mining is one of the most exciting recent tech innovations for creating digital currency tokens. Mobile mining is the creation (i.e. mining) of cryptocurrencies using just a smartphone whereas traditionally it requires elaborate setups of Graphics Processing Units (GPUs) and Application-Specific Integrated Circuits (ASICs) that consume a lot of power. Mobile crypto mining is enabled through applications like MinerGate, Mobile Miner, and Bitcoin Miner.

=== XMRig ===
 +
 +
XMRig is a high performance, open source, cross platform RandomX, KawPow, CryptoNight and GhostRider unified CPU/GPU miner and RandomX benchmark. Official binaries are available for Windows, Linux, macOS and FreeBSD.
 +
 +
==== Installation and Usage ====
 +
 +
'''System Tweaks'''
 +
 +
First, if you have 4GB or more RAM for your rig, then enable [https://xmrig.com/docs/miner/hugepages Huge Pages] support in Linux, which will improve your mining performance ...
 +
 +
sudo bash -c "echo vm.nr_hugepages=1280 >> /etc/sysctl.conf"
 +
sudo sysctl -w vm.nr_hugepages=1280
 +
 +
'''Reduce CPU Usage'''
 +
 +
In your config, look for something like:
 +
 +
"rx/0": [-1, -1, -1],
 +
 +
The number of -1's will be the number of threads the miner will use (in the above case, it's configured to use 3 threads). Just start removing -1's until you get the overall CPU usage you're looking for.
 +
 +
'''Compile Software'''
 +
 +
[https://xmrig.com/docs/miner/build/ubuntu Installation on Linux]
 +
 +
[https://xmrig.com/docs/miner/build/macos Installation on macOS]
 +
 +
[https://dev.to/ijason/cpu-mining-on-a-raspberry-pi-1e1d Installation on Raspberry Pi]
 +
 +
'''Generate Configuration'''
 +
 +
Generate your config file using the [https://xmrig.com/wizard XMRig Wizard], which will look something like this ...
 +
 +
{
 +
    "autosave": true,
 +
    "cpu": true,
 +
    "opencl": false,
 +
    "cuda": false,

Download and extract/unzip the Helium Nebra OS image for the Bobcat RK3566. https://github.com/NebraLtd/helium-bobcat-rk3566/releases
 +
 +
Open the case of the Bobcat unit so you can access the two small buttons on the board labeled "reset" and "recovery" or similar.  You will need a T9 Torx Screwdriver - https://www.ebay.co.uk/itm/193865952874 or just the end bit https://www.ebay.co.uk/itm/334425081302
 +
 +
Use a micro USB cable to connect the Bobcat to your PC (below instructions for Mac and Linux). The Bobcat has two micro USB connectors; use the one that's accessible from the back panel (labeled "USB_OTG" on the PCB).
 +
 +
Power the Bobcat via its regular power adapter while connected to the PC via micro USB.
 +
 +
Press and hold the "recovery" button; quickly press and release the "reset" button; release the "recovery" button after about 1 second. This will put your device into the so-called "loader" mode.
 +
 +
Then run ...
 +
 +
sudo rkdeveloptool ld
 +
 +
... which should print a device in "loader" mode.
 +
 +
'''DevNo=1 Vid=0x2207,Pid=0x350a,LocationID=102 Loader'''
 +
 +
Then run ...
 +
 +
sudo rkdeveloptool ef
 +
 +
... which should take about one minute to erase the flash.
 +
 +
'''Erasing flash complete.'''
 +
 +
Then you need to reset the board by pressing the reset button, and afterwards run ...
 +
 +
sudo rkdeveloptool ld
 +
 +
... which should print a device in "maskrom" mode.
 +
 +
'''DevNo=1 Vid=0x2207,Pid=0x350a,LocationID=102 Maskrom'''
 +
 +
Then download and install the new ROM with ...
 +
 +
wget <nowiki>https://dl.radxa.com/rock3/images/loader/rock-3a/rk356x_spl_loader_ddr1056_v1.10.111.bin</nowiki>
 +
sudo rkdeveloptool db rk356x_spl_loader_ddr1056_v1.10.111.bin
 +
 +
... which downloads and installs the bootloader used for various rkdeveloptool commands.
 +
 +

 +
'''Downloading bootloader succeeded.'''
 +
 +
Then run ...
 +
 +
sudo rkdeveloptool td
 +
 +
... which should succeed communicating with the device.
 +
 +
'''Test Device OK.'''
 +
 +
Then run ...
 +
 +
sudo rkdeveloptool wl 0 /path/to/extracted_nebra_image.img
 +
 +
... replacing with the actual image path. This will write the OS image onto the eMMC at address 0.
 +
 +
'''Write LBA from file (100%)'''
 +
 +
Then you just need to reset (press reset button) the board and enjoy Nebra firmware.
 +
 +
You will need to use Ethernet initially. And you can set up the WiFi again using the Nebra app over Bluetooth.
 +
 +
You can verify its working by checking the following ...
 +
 +
* device will appear in your network with hostname of nebra-xxxxxx where the Xs are the last 6 digits of the MAC address (this will be a different MAC address to what is printed on the device label)
 +
* after the unit has fully booted you will see a green light flashing
 +
* after the unit has fully booted you should see a Bluetooth device advertised for 5 minutes after it boots up (either via the Nebra hotspot app or another Bluetooth scanner app)
 +
* after the unit has fully booted up you should be able to access the Nebra diagnostics page on the local IP address of the miner or the hostname mentioned above using http://nebra-xxxxxx/ or http://nebra-xxxxxx.local/ where the Xs are the last 6 digits of the MAC address (this will be a different MAC address to what is printed on the device label)
 +
* after the unit has fully booted you should be able to see an SSH client on port 22222 (you won't be able to log in but you should be able to see/ping it)
 +
 +
Good luck.

Cryptocurrency is decentralized digital money designed to be used over the internet. Bitcoin, which launched in 2008, was the first cryptocurrency, and it remains by far the biggest, most influential, and best-known. In the years since, Bitcoin and other cryptocurrencies like Ethereum have grown as digital alternatives to money issued by governments. There are now over 20,000 different cryptocurrencies in circulation.

The Blockchain

Cryptocurrency hinges on The Blockchain. It would not exist without it.

Short Explanation

“The blockchain” is a decentralized, immutable digital ledger that records transactions across a network, ensuring transparency and security in cryptocurrencies like Bitcoin.

Long Explanation

The cryptocurrency blockchain is a revolutionary technology that underpins digital currencies like Bitcoin. It functions as a decentralized, distributed ledger, recording and verifying transactions across a network of computers. Unlike traditional financial systems, there's no central authority; instead, a consensus mechanism ensures trust among participants.

Each block in the chain contains a batch of transactions, and once confirmed, it becomes immutable. This immutability ensures security and prevents tampering, making the blockchain highly transparent and resistant to fraud. Participants, called nodes, maintain copies of the entire blockchain, adding new blocks through complex cryptographic processes, like mining.

This innovation has far-reaching implications, extending beyond finance to supply chain management, voting systems, and more, due to its potential for secure, transparent record-keeping in various fields.

Blockchain Difficulty

This is one of the most important parts of mining to understand. ‘Difficulty’ is how the puzzle adjusts in order to maintain a level playing field and network stability. It takes a lot of computing power to create ‘hashes’ in order to try to solve the puzzle.

But if millions of people are all trying to solve the puzzle with lots of computing power, then the puzzle will get solved more quickly and more frequently, right?

Wrong. The network difficulty adjusts itself to maintain more or less the same block time (eg. ~10 minutes for Bitcoin), meaning more or less the same probability of validating a block. The more miners are mining (trying to solve the puzzle with their computer power) the harder the difficulty gets. When this happens, miners need even more computing power to solve the puzzle, so those who don’t have enough (older machines for example) either upgrade their hardware, buy more hardware, or stop mining (since the extra cost of hardware + electricity makes mining for them unprofitable or less profitable during the time difficulty is high).

So what happens then? Doesn’t that mean it’s not profitable for anyone?

Well then many miners stop mining since they are not profitable, but when miners start to drop off the network, the difficulty adjusts downwards (easier) and mining becomes more profitable again (less hashpower needed to solve the puzzle during when difficulty is easy, since less computer power is needed, resulting in lower operating cost), and the cycle repeats.

How can I safely delete the blockchain on my Bitcoin Node and start a sync again?

Q - I have bitcoind installed and I'd like to free up space by deleting the blockchain from my .bitcoin directory. What set of files and directories should I delete such that the next time I start bitcoind it will recover gracefully by downloading the blockchain again?

A - Delete the "blocks" and "chainstate" directories.

Transactions

Recurring Buys

Recurring buys are repeated, automatic purchases of cryptocurrency. By using dollar-cost-averaging (DCA) — investing a fixed amount of cash at regular time intervals, used commonly by investors — investing can be less risky. It is a good way of avoiding price fluctuation. Recurring buys use DCA to automatically carry out trades.

Recurring Buys And Why You Should Start Doing It With Your Crypto

Coinbase

You have the option to set up recurring buys for the assets of your choice. Acceptable payment methods include your cash balance (USD, GBP, EUR, etc.), ACH (US only), EBT (UK only), or 3D secure cards.

The following frequencies are offered:

  • Daily: Every day starting the day you set up the recurring buy
  • Weekly: Every week on the day that you set up the recurring buy
  • 1st and 15th of the month: Twice a month (plus the day that you set up the recurring buy)
  • Monthly: Every month on the 30th (plus the day that you set up the recurring buy)

Bots

What Is a Crypto Trading Bot?

A crypto trading bot is a computer program that uses artificial intelligence and advanced algorithms to automate the buying and selling of cryptocurrencies. Acting as a virtual assistant, these bots analyze vast amounts of market data, identify patterns, and execute trades in the crypto market accordingly. They can simplify the trading process and provide a competitive edge by leveraging real-time and historical market data.

Much like the crypto market that never sleeps, crypto trading bots can operate 24/7, taking advantage of market opportunities even when you cannot actively monitor the market. By automating trading actions, these bots aim to optimize trading strategies, improve efficiency, and potentially increase profits.

How Do Trading Bots Work?

There are two kinds of crypto bots: one that needs to connect to cryptocurrency exchanges like KuCoin, where they can access real-time and historical market data, and the other that is offered directly by crypto exchanges on their platforms like KuCoin’s trading bots, which require no technical expertise to configure. By setting predefined parameters and trading strategies, you can configure your bots to execute trades automatically when specific market conditions are met.

https://www.kucoin.com/learn/trading/what-are-crypto-trading-bots

What are the types of Crypto Trading Bot?

Spot Grid - Spot grid trading bot is particularly effective in ranging crypto market conditions. It thrives when the prices of cryptocurrencies move within a certain range, as the grid structure enables users to profit from the recurring price oscillations that are characteristic of such market conditions. By intelligently placing buy and sell orders within this range, the KuCoin Spot Grid trading bot excels in harnessing price movements and market trends, making it a valuable tool for traders seeking to navigate and capitalize on a range-bound cryptocurrency market.

Martingale - KuCoin’s Martingale trading bot implements a high-risk, high-reward strategy. It increases the trade size after a losing trade, aiming to recover losses with larger subsequent trades. This strategy requires careful risk management to prevent significant loss. The KuCoin Martingale trading bot automates the Martingale strategy, allowing you to capitalize on the volatility of crypto markets. The bot buys more when prices fall and sells when prices rise, effectively betting on the reversal of a downtrend. It is best suited for traders who are willing to take calculated risks and believe in their chosen crypto asset's potential to recover from lows. The bot operates 24/7, adjusting its trading volumes based on price movements, and is free to use, with the only charges being transaction costs incurred during the buying and selling of cryptos.

How to withdraw GBP from Binance using P2P

DO THIS ON YOUR MOBILE PHONE APP

This is a way to move your money from Binance to an external fiat bank account. It is quite complex but it is safe because Binance guides you through the process and you do not release you crypto until you confirm you have received your fiat to your bank account.

  1. Convert your wallet balance to USDT
  2. Transfer the amount of USDT you want to withdraw to your Funding account - Assets > Spot > USDT > Transfer > Funding
  3. Home > P2P or Icon top left > More Services > Trade > P2P
  4. Make sure the currency to want to use is GBP in the top right next to the horizontal arrows icon
  5. Click on the Sell tab and make sure USDT is selected
  6. This will show you all the peers or 'buyers' for your crypto
  7. Click on Amount to narrow the filter by £x amount - e.g. £10
  8. Choose the peer that has the highest amount of trades, completion ratio and 100% feedback
  9. Click on Sell button and choose 'By Crypto'
  10. Select the Payment Method and Add Bank Account details (you will notice that the Sort Code is missing)
  11. Choose the amount of USDT to sell and click on Sell USDT
  12. Now it will show Waiting for Buyer's Payment
  13. Keep an eye on the yellow chat icon for a message from the buyer
  14. When a message arrives, click on the chat icon and type in your bank's Sort Code when asked
  15. Keep watching for any other messages from the buyer
  16. Eventually (this took 30 minutes for NatWest) you will see a message from Coinbase confirming that the £GBP has been sent to your bank account
  17. Switch to your bank app and check that the £GBP have arrived from the same name as shown on Binance P2P
  18. When you are happy, go back to the Binance app and click Payment Received and confirm twice
  19. Leave some positive feedback for the trader and that's it!

Staking

Staking is a process by which individuals lock their cryptocurrency (their "stake") to support the security and operation of a blockchain network. When someone stakes their coins, they are essentially helping to secure the chain and validate transactions on the blockchain.

Staking is only possible on blockchains such as Ethereum and Cardano based on a proof-of-stake (PoS) consensus mechanism. PoS differs from the proof-of-work (PoW) used in cryptocurrencies such as Bitcoin, where miners use computing power to validate transactions. Staking coins makes users' holdings less liquid because the coins are tied up in the staking process.

Individuals can usually still access their staked coins but may only be able to use them for other purposes once they are no longer staked. You can unstake your crypto at any time, and your crypto is always yours.

Example rates ...

  • Solana = 4.35%
  • Ethereum = 3.29%
  • Cardano = 2.00%

Stablecoins

Stablecoins are tokens pegged to an external asset, such as gold or the U.S. dollar, which ensures price stability. These coins are usually backed by the external asset, commonly USD, minimizing risk. Nonetheless, some stablecoins are collateralized by other cryptocurrencies, which elevates the risk factor. Stablecoins are generally less volatile. For instance, USDC remains fixed at $1 and is supported by numerous financial institutions. In a highly unstable market, stablecoins offer stability by being collateralized.

  • US Dollar Coin (USDC) = 4.60%

Wallets

What is a crypto wallet?

Crypto wallets allow you to store, send, and receive cryptocurrencies.

Wallets are usually either hot, cold, or centralized:

  • Hot wallets connect to the internet and are usually easy to use
  • Cold wallets do not connect to the internet and offer the best security
  • Centralized wallets, such as exchanges, are controlled by third parties

When using a crypto wallet, the crypto is not stored in the wallet but on the blockchain. Crypto wallets use your secret recovery phrase to access and interact with your funds on the blockchain.

How do Crypto Wallets work?

The beauty of a crypto wallet is down to the fact that it does not store any actual money on it. When you create a crypto wallet, the software (like those listed below) generates a key from a 12 or 24 word 'seed phrase' and embeds this key in the blockchain - so it knows what the wallet is for and what it contains. There is NO name or email address or password involved. This is constantly being verified IN the blockchain and updated to match what you have in your wallet. Which means, you can install ANY crypto wallet software, import your unique 12 word key and your balance will be shown.

Lightning

The Lightning Network is designed to make bitcoin transactions as fast and cheap as possible. It is part of a newer class of crypto technologies known as "layer 2" blockchains, which you can think of as being a little like HOV lanes on highways. By offloading some transaction "traffic" to the Lightning Network's "layer 2" blockchain, the core Bitcoin blockchain ("layer 1") can move faster.

Node

What Is A Full Node?

A full node is a program that fully validates transactions and blocks. Almost all full nodes also help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes.

Most full nodes also serve lightweight clients by allowing them to transmit their transactions to the network and by notifying them when a transaction affects their wallet. If not enough nodes perform this function, clients won’t be able to connect through the peer-to-peer network—they’ll have to use centralized services instead.

Many people and organizations volunteer to run full nodes using spare computing and bandwidth resources—but more volunteers are needed to allow Bitcoin to continue to grow.

Mining

What is Bitcoin Mining?

Bitcoin mining is the process of adding new transactions to the blockchain, a public ledger of all Bitcoin transactions. This is done by using powerful computers to solve complex mathematical equations that verify the authenticity of the transactions and add them to the blockchain. Miners are rewarded with newly created bitcoins for their efforts, known as a "block".

What is Cryptocurrency Mining?

Cryptocurrency mining is the process of validating transactions and adding them to a blockchain by solving complex mathematical puzzles, typically done using powerful computers to earn rewards.

Mining is the process that Bitcoin and several other cryptocurrencies use to generate new coins and verify new transactions. It involves vast, decentralized networks of computers around the world that verify and secure blockchains - the virtual ledgers that document cryptocurrency transactions.

The more powerful your computer, the more "hash rate" it has and can contribute a higher percentage of solving the puzzle and gain a higher reward.

Crypto mining is a calculation-intensive, puzzle-solving-like computation process that requires high processing power along with high electricity consumption. The miner who first solves the puzzle gets to place the next block on the blockchain and claim the rewards. Rewards include the miner becoming the owner of the newly released bitcoin, or getting fees linked to the transactions performed in the block.

At the earliest days of the mining, any processor or GPU had the sufficient power required for finding many solutions per day and getting a reward for the detected block.

With an increase of the interest in cryptocurrencies, the difficulty level of the "puzzles" also increased, and a standalone PC could not find many solutions anymore.

Difficulty level was rising because the reward for the newfound block was growing as well as its equivalent in value. That was the time when miners decided to unite their efforts and create the mining pools.

Therefore, even weak devices that are working simultaneously on solving the same "puzzle" have a chance to find its solution which would enable miners to create a new block.

Mining pools get solutions from all the connected miners, and if one of those numerous solutions appears to be a proper one, the pool gets a reward for the created block. This reward is shared proportionally to the efforts applied by the miners and forwarded to their wallets. 

Farm > Rig > Worker

The miner, or worker, can be either CPU, GPU or ASIC based.

  • CPU = Central Processing Unit
  • GPU = Graphics Processing Unit
  • ASIC = Application Specific Integrated Circuit

Today, there are thousands of dedicated farms around the world running millions of rigs.

How Many Bitcoins Are There?

  • 19,489,350 = Total BTC in Existence
  • 1,510,650 = Bitcoins Left to Be Mined
  • 92.806% = Percentage of Bitcoins Issued
  • 900 = New Bitcoins per Day

Hash Rate

How Is The Hash Rate Measured & its Unit?

Hash rate is a unit measured in hashes per second or [h/s] and here are some usual denominations used to refer it.

Hash rate denominations 

1 kH/s is 1,000 (one thousand) hashes per second - "kilohash".
1 MH/s is 1,000,000 (one million) hashes per second - "megahash".
1 GH/s is 1,000,000,000 (one billion) hashes per second - "gigahash".
1 TH/s is 1,000,000,000,000 (one trillion) hashes per second - "terahash".
1 PH/s is 1,000,000,000,000,000 (one quadrillion) hashes per second - "petahash".
1 EH/s is 1,000,000,000,000,000,000 (one quintillion) hashes per second - "extahash".

Hard Drive Mining

What Is Hard Drive Mining?

Hard drive mining is a way of generating cryptocurrency using the storage space of hard disk drives. HDD miners do not require graphics processing units (GPUs) or ASIC miners, like in traditional mining farms, to produce new blocks in the distributed ledger. Instead, this method uses a set of hard disk drives and unused storage space, also known as proof of capacity.

Practically any device with loads of storage space can be used in HDD mining, as it needs less computational power than the Proof of Work, thus using less energy in the long term. New data blocks are generated when miners use their hard disks in the distributed ledger and, accordingly, get rewarded.

Chia

Chia is a cryptocurrency and blockchain with smart transaction capabilities. It was designed from the ground up to make cryptocurrency easier to use (and harder to lose) than cash.

The 'Proof of Space and Time' is the only Nakamoto consensus algorithm since Proof of Work, while also having a much lower energy consumption. Part of Chia's vision involves improving the carbon footprint of the blockchain industry.

Chia Farming

CHIA FARMING BASICS

Chia plotting and farming can seem daunting at first, but it's a relatively straightforward process:

  1. Obtain hardware
  2. Install Chia
  3. Run and configure Chia
  4. Create a plot
  5. Start farming

Pools and Payouts

When you join a pool, you are given a 'payout address' which is generated from your main 'Chia Wallet'.

When you farm to a pool, you gradually build up mojo and when the minimum amount of mojo has been farmed (or mined) then the Pool will payout to your address.

You then view your wallet balance and can send your mojos to an external exchange address.

To make this process quicker, you can change your Pool's payout address to that external exchange address.

Here are the cli commands to do all of this in the Linux terminal:-

1. Make sure your database in fully synced ... 

chia show --state

2. Show your wallet with the balance ... 

chia wallet show

3. Show the pools you have joined and are mining to ... 

chia plotnft show

4. Change the pool's payout address ... 

chia plotnft change_payout_instructions --launcher_id 2bb32xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx62738a --address xch1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx95m4

5. Send mojos to an external address ... 

chia wallet send --amount 0.002261969048 --fee 0.000000000001 --address xch1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx95m4

K=33     512 GiB (550 GB)      208.8 GiB (224.2 GB)
K=34     1041 GiB (1118 GB)    429.8 GiB (461.5 GB)
K=35     2175 GiB (2335 GB)    884.1 GiB (949.3 GB)

When planning on how much plotting space is required, only calculate the temporary disk size requirement.

Mobile Phone Mining

Mobile mining is one of the most exciting recent tech innovations for creating digital currency tokens. Mobile mining is the creation (i.e. mining) of cryptocurrencies using just a smartphone whereas traditionally it requires elaborate setups of Graphics Processing Units (GPUs) and Application-Specific Integrated Circuits (ASICs) that consume a lot of power. Mobile crypto mining is enabled through applications like MinerGate, Mobile Miner, and Bitcoin Miner.

XMRig

XMRig is a high performance, open source, cross platform RandomX, KawPow, CryptoNight and GhostRider unified CPU/GPU miner and RandomX benchmark. Official binaries are available for Windows, Linux, macOS and FreeBSD.

Installation and Usage

System Tweaks

First, if you have 4GB or more RAM for your rig, then enable Huge Pages support in Linux, which will improve your mining performance ... 

sudo bash -c "echo vm.nr_hugepages=1280 >> /etc/sysctl.conf"
sudo sysctl -w vm.nr_hugepages=1280

Reduce CPU Usage

In your config, look for something like: 

"rx/0": [-1, -1, -1],

The number of -1's will be the number of threads the miner will use (in the above case, it's configured to use 3 threads). Just start removing -1's until you get the overall CPU usage you're looking for.

Compile Software

Installation on Linux

Installation on macOS

Installation on Raspberry Pi

Generate Configuration

Generate your config file using the XMRig Wizard, which will look something like this ... 

{
   "autosave": true,
   "cpu": true,
   "opencl": false,
   "cuda": false,
   "pools": [
       {
           "coin": "monero",
           "algo": "rx/0",

           "tls": false,
           "keepalive": true,
           "nicehash": true
       }
   ]
}

Hiveon

Hiveon is the ultimate mining platform which allows users to setup, mine and control processes more effectively and hassle-free across thousands of rigs all from a single place. Everything you and your team need to keep your farm at peak efficiency.

  • Farm = a group of rigs which mine.
  • Rig = a mining device equipped with a motherboard, CPU, RAM, SSD/HDD, and GPU.
  • Worker = a piece of hardware which will mine.

Setup

Download the zip installer to burn on to an SSD

I really needed these simple, step by step instructions because it is not clear and some of the links are dead (sigh).

STAGE 1

  1. create an account at Hiveon
  2. confirm the link in the email
  3. log in
  4. your first farm will be automatically created
  5. click add rig
  6. follow the wizard to download the Hiveon OS and burn it to your USB drive
  7. in the wizard, download the rig.conf file
  8. when the USB drive has finished being created, take it out, then back in and mount HIVE partition
  9. copy that rig.conf file to the HIVE partition and then unmount the drive partition
  10. pull out the drive and put it in your mining rig computer
  11. start the computer and watch your Hiveon Dashboard for the rig to appear in your farm

Then you install these extra programs ... 

sudo apt-get install gcc g++

Then you can continue to compile ... 

aclocal
autoreconf -f -i
CXXCPP=/usr/bin/cpp ./configure
make

Copy the software to your main system location, ready for running ... 

sudo cp -av rkdeveloptool /usr/local/bin/
sudo ldconfig

Test to make sure it works ... 

rkdeveloptool -v

Download and extract/unzip the Helium Nebra OS image for the Bobcat RK3566. https://github.com/NebraLtd/helium-bobcat-rk3566/releases

Open the case of the Bobcat unit so you can access the two small buttons on the board labeled "reset" and "recovery" or similar. You will need a T9 Torx Screwdriver - https://www.ebay.co.uk/itm/193865952874 or just the end bit https://www.ebay.co.uk/itm/334425081302

Use a micro USB cable to connect the Bobcat to your PC (below instructions for Mac and Linux). The Bobcat has two micro USB connectors; use the one that's accessible from the back panel (labeled "USB_OTG" on the PCB).

Power the Bobcat via its regular power adapter while connected to the PC via micro USB.

Press and hold the "recovery" button; quickly press and release the "reset" button; release the "recovery" button after about 1 second. This will put your device into the so-called "loader" mode.

Then run ... 

sudo rkdeveloptool ld

... which should print a device in "loader" mode. 

DevNo=1	Vid=0x2207,Pid=0x350a,LocationID=102	Loader

Then run ... 

sudo rkdeveloptool ef

... which should take about one minute to erase the flash. 

Erasing flash complete.

Then you need to reset the board by pressing the reset button, and afterwards run ... 

sudo rkdeveloptool ld

... which should print a device in "maskrom" mode. 

DevNo=1	Vid=0x2207,Pid=0x350a,LocationID=102	Maskrom

Then download and install the new ROM with ... 

wget https://dl.radxa.com/rock3/images/loader/rock-3a/rk356x_spl_loader_ddr1056_v1.10.111.bin
sudo rkdeveloptool db rk356x_spl_loader_ddr1056_v1.10.111.bin

... which downloads and installs the bootloader used for various rkdeveloptool commands. 

‘rk356x_spl_loader_ddr1056_v1.10.111.bin’ saved [453056/453056]
Downloading bootloader succeeded.

Then run ... 

sudo rkdeveloptool td

... which should succeed communicating with the device. 

Test Device OK.

Then run ... 

sudo rkdeveloptool wl 0 /path/to/extracted_nebra_image.img

... replacing with the actual image path. This will write the OS image onto the eMMC at address 0. 

Write LBA from file (100%)

Then you just need to reset (press reset button) the board and enjoy Nebra firmware.

You will need to use Ethernet initially. And you can set up the WiFi again using the Nebra app over Bluetooth.

You can verify its working by checking the following ...

  • device will appear in your network with hostname of nebra-xxxxxx where the Xs are the last 6 digits of the MAC address (this will be a different MAC address to what is printed on the device label)
  • after the unit has fully booted you will see a green light flashing
  • after the unit has fully booted you should see a Bluetooth device advertised for 5 minutes after it boots up (either via the Nebra hotspot app or another Bluetooth scanner app)
  • after the unit has fully booted up you should be able to access the Nebra diagnostics page on the local IP address of the miner or the hostname mentioned above using http://nebra-xxxxxx/ or http://nebra-xxxxxx.local/ where the Xs are the last 6 digits of the MAC address (this will be a different MAC address to what is printed on the device label)
  • after the unit has fully booted you should be able to see an SSH client on port 22222 (you won't be able to log in but you should be able to see/ping it)

Good luck.

BitAxe

The BitAxe is a fully open source hardware Bitcoin ASIC miner.

GitHub

BitAxe 201 - It says U.S. only but use a reshipping service like Stackry or MyUS to get it to the U.K. ;-)

Update

https://github.com/skot/ESP-Miner/releases

Troubleshooting

Make sure you only put the domain name part in to the Axe OS Settings page e.g. eu.stratum.braiins.com and not stratum+tcp://eu.stratum.braiins.com:3333

If the Wireless will not connect, you can take the miner out of range of your wifi and use the USB port to provide enough power just to do the settings. The miner will try 5 times to connect and then will reset itself and you can connect to its own wifi hotspot to redo the settings again. The RESET button on the board does not work at this time.
