How to Mine Bitcoin

A variety of hardware and software can be used to mine bitcoin. When the Bitcoin blockchain was first released, it was possible to mine it competitively on a personal computer; however, as it became more popular, more miners joined the network, which lowered the chances of being the one to solve the hash. You can still use your personal computer as a miner if it has newer hardware, but the chances of solving a hash individually using a home computer are minuscule.
This is because you're competing with a network of miners that generate around 560 quintillion hashes (on Feb. 24, 2024) per second. Machines—called Application Specific Integrated Circuits (ASICs), have been built specifically for mining—can generate more than 300 trillion hashes per second. In contrast, a computer with the latest hardware hashes around 100 megahashes per second (100 million).5
To successfully become a bitcoin miner, you have several options. You can use your existing computer to use mining software compatible with Bitcoin software and join a mining pool. Mining pools are groups of miners that combine their computational power to compete with large ASIC mining farms.
If you have the financial means, you could purchase an ASIC miner. You can generally find a new one for around $10,000, but used ones are also sold by miners as they upgrade their systems. There are some significant costs, such as electricity and cooling, to consider if you purchase one or more ASICs. Keep in mind using one or two ASICs is still no guarantee of rewards as you're competing with large mining farms of hundreds, if not thousands, of ASICs.
There are several mining programs to choose from and many pools you can join. Two of the most well-known programs are CGMiner and BFGMiner. Some of the most popular pools are Foundry Digital, Antpool, F2Pool, ViaBTC, and Binance.com.
When choosing a pool, it's important to make sure you find out how they pay out rewards, what any fees might be, and read some mining pool reviews.
