Market share of 15 Bitcoin (BTC) mining pools on April 14, 2021
The world's top Bitcoin mining pools all come from China, with five pools being responsible for more than half of the cryptocurrency's total hash. Hashing refers to the amount of processing power that PCs use to build the blockchain: the more blocks of verified transactions that are processed or "hashed", the more Bitcoin - the reward for this verification process - is being mined. Simply put, the higher the hashrate - or the hash power of the overall network - the more secure it is. In 2020, China was responsible for mining more than half of all the Bitcoins in the world.
