China’s Bitcoin mining sector is quietly rebounding four years after a nationwide ban, as operators tap cheap electricity and excess data center capacity in energy-rich regions. Industry estimates suggest China has regained roughly 14% of global hashrate by late October 2025, placing it third worldwide, according to Hashrate Index data cited by Reuters.
Mining Activity Returns Despite 2021 Ban
Beijing’s 2021 crackdown forced miners to shut down or relocate abroad, but recent industry data and miner accounts indicate a steady resurgence within several western and southwestern provinces, including Xinjiang. The recovery is largely occurring outside formal approval and reflects uneven enforcement across local jurisdictions.
Economics and Infrastructure Drive the Rebound
Miners and market participants say the revival is being propelled by a combination of lower energy costs, overbuilt compute infrastructure, and improved mining economics as Bitcoin’s price climbed in October.
- Cheap electricity in energy-rich provinces
- Unused energy capacity and surplus data centers
- Improved profitability on higher Bitcoin prices
- Policy ambiguity and softer enforcement in some locales
“The resurgence of mining activity in China is one of the most important signals the market has seen in years,” said Patrick Gruhn, CEO of crypto market infrastructure provider Perpetuals.com, in comments reported by Reuters. Gruhn added that the trend raises questions about decentralization as hashrate concentrates among a few leading jurisdictions.
China Regains Global Standing
After its market share fell to near zero in 2021, China has climbed back to an estimated 14% of global hashrate as of late October, Hashrate Index data show. That recovery positions the country behind only two other nations by mining capacity. The resurgence underscores the pull of low-cost power and available rack space created by a surge in data center construction over the past two years.
What to Watch
Industry participants are watching whether Beijing formalizes tolerance for mining in certain regions or reasserts enforcement. Concentration risks remain a focal point for the Bitcoin network as a handful of countries now dominate global hashrate. For now, economic incentives supporting underground operations—especially in Xinjiang and other energy-abundant provinces—show few signs of fading.
