BlockBeats News, December 15 — Kong Jianping, co-chairman of the board of directors of original Canaan Creative, now founder and chairman of Nano Labs, cited his previous tweet "Bitcoin mining farms in Xinjiang are gradually shutting down" to indicate that, considering the recent decline in Bitcoin hash rate, at an average of 250T (hash rate per machine), at least 400,000 Bitcoin mining machines have shut down recently. Previously, according to F2pool data, the total network hash rate of Bitcoin was reported at 988.49EH/s, a 17.25% decrease compared to the same time last week. Notably, foreign media reported in November that Bitcoin mining activities in Xinjiang and other regions of China have become active again. By the end of October 2025, China’s Bitcoin mining hash rate share had rebounded to about 14% (the third largest in the world). Subsequently, on the 28th, the People's Bank of China, led by thirteen departments, launched a campaign to crack down on virtual currency trading and speculation.
