Bitcoin mining is quietly resurging in China, four years after Beijing imposed a sweeping ban on all cryptocurrency-related activities in 2021. Despite the prohibition, miners are taking advantage of cheap electricity and expanding data center demand in energy-rich provinces such as Xinjiang. Before the ban, China was the world’s largest Bitcoin mining hub, but its share dropped to zero after the crackdown. According to Hashrate Index, China has now regained around 14% of global mining activity, ranking third worldwide. The resurgence has also boosted sales for local mining rig manufacturers like Canaan Inc. Industry insiders say miners are exploiting surplus electricity that cannot be exported, making mining profitable again. The Chinese government has not commented on the renewed activity, and analysts note that the revival coincided with Bitcoin’s price surge in October, driven by U.S. policy shifts and weakening confidence in the dollar. However, global risk aversion has since caused Bitcoin’s value to fall by about one-third from its peak.
