The BTC com pool was founded in September 2016 and is a subsidiary of Bitmain, one of the world's largest mining equipment manufacturers. This pool has been the one with the most mining power in Bitcoin for the previous few years. The hash rate recorded by BTCcom has been so high at times that network users have been concerned about 51 percent assaults or block rearrangement by Bitmain pools.
BTC com has servers in China (Beijing and Shenzen), the United States, and Europe, and presently provides 13.8 exahashes per second of computing power, or roughly 22% of Bitcoin's overall hash rate which is a good rate.
