Crypto mining is a process that allows you to use specialized hardware or software to generate new crypto coins. Crypto miners help verify transactions on the blockchain, and in return they are rewarded with cryptocurrency incentives, enabling them to earn passive income.
Although cryptocurrencies like Bitcoin have a fixed total supply, not all bitcoins that will ever exist are already on the market. New coins are being added to the circulating supply gradually, and mining Bitcoin is a process in which people compete to solve complicated math equations in order to gain new coins.
At first, people could mine all cryptocurrencies using a normal computer or laptop. Although you can still mine some coins on your PC, nowadays most cryptocurrencies require specialized hardware called “crypto miners” or “mining rigs” to mine them.
Mining rigs are powerful machines built with multiple GPUs (Graphical Processing Units). Specialized crypto mining companies own dedicated cryptocurrency mining facilities that host hundreds of crypto miners, but many people are also able to make a profit by owning just a single mining rig in their homes.
However, it’s worth noting that crypto miners require a lot of electric energy to function. Because of that, mining cryptocurrency is not feasible for anyone – in order to truly profit from it, you need to live in a country with cheap electric energy, or you must have access to a source of renewable energy such as wind turbines or solar panels.
For many crypto skeptics, the high energy consumption of crypto mining is an argument against cryptocurrencies in general. However, over 80% of cryptocurrency mining is done using green energy sources, which makes crypto mining one of the most eco-friendly industries in the world.
It’s also worth noting that not all cryptocurrencies can be mined – you can only mine coins built with the Proof of Work (PoW) algorithm, such as Bitcoin (BTC), Ethereum (ETH) and Monero (XMR). Cryptocurrencies that utilize the Proof of Stake (PoS) algorithm cannot be mined.
