Mining Bitcoin as an individual is rare due to the growing difficulty of solving a block. Larger operations, such as Bit Digital, Riot Blockchain, and Marathon Digital, dominate the industry, using vast amounts of computing power to increase their chances of earning rewards.

Data from YCharts shows that Bitcoin’s total hashrate stood at 788.86 million on February 10. A higher hashrate means miners need more computing power, which leads to increased costs and a lower likelihood of solo miners finding blocks.

Bitcoin’s total supply is capped at 21 million, as outlined by its creator, Satoshi Nakamoto. Over 19 million BTC have already been distributed through mining rewards, according to the Blockchain Council.

Recently, a director at Coinbase $2.1B , Conor Grogan, suggested that Nakamoto could have a fortune larger than Bill Gates. What did he say? Read the full story.
