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.

Buying
The easiest way to acquire cryptocurrency is to purchase on an online exchange like Coinbase, which is the world's most trusted and most secure platform to buy, sell and manage crypto.

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)

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
This is really, really clever.
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 2048 recovery words defined in the BIP39 standard.
This MUST be written down, or etched in Steel. No seriously, really etched in 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.

Hodling
Bitcoin hodling is a strategy that involves continuous storage of bitcoins as a way to mitigate volatility and make considerable returns. While this method takes a lot of time to show tangible results and requires patience, it is one of the safest and most solid ways to take advantage of Bitcoin.
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.
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.

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
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",

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
I really needed these simple, step by step instructions because it is not clear and some of the links are dead (sigh).
STAGE 1
- create an account at Hiveon
- confirm the link in the email
- log in
- your first farm will be automatically created
- click add rig
- follow the wizard to download the Hiveon OS and burn it to your USB drive
- in the wizard, download the rig.conf file
- when the USB drive has finished being created, take it out, then back in and mount HIVE partition
- copy that rig.conf file to the HIVE partition and then unmount the drive partition
- pull out the drive and put it in your mining rig computer
- start the computer and watch your Hiveon Dashboard for the rig to appear in your farm

Fix OLD Firmware Bug With NEW Nebra Firmware
NEBRA Firmware and Instructions
DISCORD INSTRUCTIONS
This method is tested and verified now on Linux and Mac ... (Image only currently works on g290 and g295)...
We also support g280 (which is the 1gb bobcat, this uses a different image though and can run using SD card. See https://support.nebra.com/support/solutions/articles/24000085839-getting-started-with-bobcat-1g
sudo apt update sudo apt install snapd sudo reboot sudo snap install core sudo snap install rkdeveloptool --edge
Follow these instructions to install the Rockchip flashing tools depending on the OS you run on your PC: https://wiki.radxa.com/Rock3/install/rockchip-flash-tools.
If you try to compile on Linux and you receive this error ...
configure: error: C++ preprocessor fails sanity check
Then you look in side the error.log file and find this ...
cpp: fatal error: cannot execute 'cc1plus': execvp: No such file or directory
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.

Hardware Miners
altcoin usb miners. Work great for beginners and novice alike. Windows drivers installed on hardware so it's basically plug and play. Cgminer and bfgminer work great with linux. A USB hub and a few of these miners and you will have your own little mining farm. Raspberry pi makes good controller board.
