@vfrmedia @stux The China ban didn't really work though. From Cambridge / CCAF:

> Most notably, however, is China’s apparent comeback. Following the government ban in June 2021, reported hashrate for the entire country effectively plummeted to zero during the months of July and August. Yet reported hashrate suddenly surged back to 30.47 EH/s in September 2021, instantly catapulting China to second place globally in terms of installed mining capacity (22.29% of total market). This strongly suggests that significant underground mining activity has formed in the country, which empirically confirms what industry insiders have long been assuming. Access to off-grid electricity and geographically scattered, small-scale operations are among the major means used by underground miners to hide their operations from authorities and circumvent the ban (5).
