In a stunning reversal of fortune, China's Bitcoin mining industry has quietly staged a comeback. Despite the official ban imposed in 2021, new data from Hashrate Index shows that China has regained its position as the world's third-largest Bitcoin mining hub, accounting for roughly 14% of the global hashrate as of late October 2025 – up from virtually zero after the crackdown. The resurgence is reshaping the global mining landscape and drawing intense scrutiny from analysts and policymakers.
Drivers: Cheap Electricity and Policy Loosening
Multiple factors are fueling the return. China possesses some of the world's cheapest electricity, particularly in hydro-rich southwestern provinces and coal-heavy northwestern regions. Excess capacity from data centers is also being repurposed for mining. The sustained rally in Bitcoin prices during 2024-2025 further incentivized miners to restart operations. Perhaps more crucially, Beijing's stance has softened perceptibly, with discussions around a yuan-backed stablecoin and a broader review of digital asset frameworks signaling a potential shift. An anonymous mining farm operator told local media: “As long as power costs stay low and profits are high, many local governments turn a blind eye to underground mines.”
Hardware Sales Confirm Recovery
The rebound is most vividly reflected in the sales data of mining rig manufacturers. Leading producer Canaan Inc. reported that its revenue from China surged from just 2.8% of total sales in 2022 to 30.3% in 2023, and exceeded 50% in the second quarter of 2024. The company attributed the rebound to US tariff uncertainty, higher Bitcoin prices, and China's evolving digital asset strategy. A Canaan executive noted, “Inquiries from domestic customers have multiplied compared to two years ago, and many large orders come from entities we had never engaged with before.”
Global Hashrate Map Shifts
China's reemergence is redrawing the global mining map. Countries like the United States, Kazakhstan, and Russia had benefited from the exodus of Chinese miners; now they face shrinking market share. As US-China tech tensions escalate, this recalibration could trigger new geopolitical friction. A researcher at CoinMetrics commented: “If China continues to grow at 14% or higher, US miners’ global dominance will be challenged. US regulators might intensify scrutiny of miners’ energy consumption as a result.”
Ban Remains on Paper, Enforcement Selective
It is important to note that the Chinese government has not formally rescinded the 2021 mining ban. The People's Bank of China still classifies virtual currency mining as a “phased-out industry.” However, enforcement varies by region, with some local authorities tolerating small-scale, low-energy mines for tax revenue and job creation. Bitfarms’ chief strategy officer observed, “Last month we saw an 18% increase in node connections from Chinese IPs, though many use VPNs or are distributed across subnets. The hashpower contribution is real.” This gray area makes precise measurement difficult; industry estimates range from 14% to 20% of global hashrate.
Outlook: A Tug-of-War Between Policy and Profit
The sustainability of China's mining comeback hinges on two variables: Bitcoin's price trajectory (a major drop would flush out marginal miners) and regulatory tightening. Analysts believe that with the current economic headwinds, local governments have incentives to tolerate mining for tax and employment, while the central government's push for blockchain innovation may foster a more accommodating attitude. But any risks to financial stability or capital outflows could trigger a renewed crackdown. For now, the underground tide continues, and the crypto world is watching closely.
