In response to CCAF, China’s ban on BTC mining noticed the nation’s hashrate drop to zero in July and August 2021. Nonetheless, knowledge from September 2021 to January 22 exhibits that China’s hashrate climbed to 30.47 EH/s in September. This resurgence made China the second-largest BTC miner, contributing 22.29% of the worldwide hashrate.
Explaining how China has rebounded as a number one BTC mining hub, CCAF mentioned,
This strongly means that vital underground mining exercise has fashioned within the nation, which empirically confirms what trade insiders have lengthy been assuming. Entry to off-grid electrical energy and geographically scattered, small-scale operations are among the many main means utilized by underground miners to cover their operations from authorities and circumvent the ban.
Nonetheless, it’s value noting that this knowledge relies on a analysis methodology that leverages mixture geolocation from large BTC mining swimming pools, which mix computing sources to mint new tokens successfully.

Following China’s BTC mining ban, firms within the area shut down operations and began an exodus to different jurisdictions with friendlier laws and low cost energy. The U.S. rapidly grew to become the main BTC mining hub, able to host these corporations.

Kazakhstan additionally accommodated a fair proportion of the mining firms that left China. The nation’s hashrate climbed as excessive as 27.31 EH/s in October. Nonetheless, fixed energy outages and a crackdown on unregistered BTC miners discouraged mining. Because of this, the nation’s hashrate plunged to 24.79 EH/s, bringing Kazakhstan’s market share to 13.22%.
Canada’s market share additionally fell from 9.55% in August 2021 to six.48% in January. Russia recorded a sharper drop in the identical interval, with its market share falling from 11.23% to 4.66%.
