Bitcoin mining is steadily resurfacing in China, four years after authorities outlawed the industry. Despite the ongoing nationwide ban introduced in 2021, miners—ranging from small operators to major investors—are re-establishing activity in regions rich in unused power, taking advantage of both cheap electricity and favourable infrastructure. The resurgence reflects the enduring profitability of mining at a time when Bitcoin’s price and network activity have surged, creating strong incentives to bypass regulatory risks.
China once dominated global Bitcoin production, but its share collapsed almost overnight after the ban pushed miners abroad. Recent data, however, shows a clear turnaround. China now accounts for roughly 14% of global Bitcoin mining as of October, according to Reuters reporting. Some estimates from independent studies place China’s share even higher, suggesting that up to one-fifth of the global hashrate may be operating within its borders.
Much of this recovery is concentrated in energy-abundant regions such as Xinjiang, where excess electricity often cannot be transmitted efficiently to other provinces. Miners have quietly returned to convert this surplus energy into crypto. One Xinjiang-based miner explained that using this idle power for mining has become a practical and profitable alternative, and new facilities are already being built to accommodate rising demand.
The revival is closely tied to global market conditions. Bitcoin’s rally in October, coupled with climbing network activity, sharply increased mining revenue and encouraged operators to restart machines. Local governments—facing slowing revenue growth and previously overinvesting in data centers—have also indirectly contributed by creating excess computing capacity that miners can cheaply repurpose.
Hardware manufacturers are seeing the effects as well. Canaan, one of the world’s largest mining rig producers, reported that China accounted for 30.3% of its global revenue last year, a dramatic rise from just 2.8% in 2022. The company attributed its growing domestic business to rising Bitcoin demand, uncertainties around U.S. tariffs, and signs of a more flexible stance toward digital asset-related industries within China. Although mining itself remains illegal, the sale, research, and manufacturing of mining equipment continue to operate openly under Chinese law.
Network indicators further confirm China’s increasing involvement. Bitcoin miners generated 3.14 BTC in block rewards over the past day, with transaction fees making up a small fraction of earnings. Current network difficulty stands at 152.27 trillion, and the network processed more than 1,040 exahashes per second in the past week—evidence of robust mining participation ahead of the next difficulty adjustment later this month.
Subtle shifts in regional policy attitudes have also helped miners regain momentum. Hong Kong’s push for regulated crypto markets and Beijing’s reported interest in yuan-based stablecoins suggest China is exploring controlled engagement with digital assets, even as the mining ban technically remains unchanged. Analysts say the persistence of significant mining capacity shows that strong economic incentives continue to outweigh regulatory barriers.
China’s unexpected mining comeback reinforces its lasting influence in the global Bitcoin ecosystem and hints at a steadier supply outlook as miners quietly push forward, regardless of official restrictions.
