Bitcoin’s hashrate fell by about 10% in a single day on Sunday, with Jianping Kong, former co-chairman of Bitcoin mining hardware producer Canaan, attributing it to mining farms shutting down in China’s Xinjiang autonomous region.

Kong tied the change to farms shutting down in China’s Xinjiang autonomous region. Cointelegraph was unable to verify the claims independently, but Kong’s position as a former co-chairman at a Chinese Bitcoin mining ASIC producer lends some credibility to the assertion.
According to YCharts , Bitcoin’s hashrate dropped from 1,053 TH/s on Sunday to just under 943 TH/s on Monday. This is equivalent to a loss of over 10%, or 110 TH/s. Still, the network’s total hashrate is an estimate inferred from network statistics and cannot be precisely measured.
