China still appears, on paper, to be enforcing its Bitcoin mining ban from four years ago – but the reality on the ground tells a very different story. Recent data shows the country now generates around 14% of the global Bitcoin hashrate, putting it back among the top three mining centers worldwide. This rebound signals a transformation too deep to be explained by economic pressure alone. Rapidly expanding grey-market mining in regions with cheap electricity, a renewed wave of hardware investment, and the United States’ national security probe into Bitmain have combined to redraw Bitcoin’s global power map.
How Did China’s Hashrate Share Climb Back to 14%?
The core driver of China’s renewed strength in global Bitcoin mining is a sharp rise in hashrate production over the past year. Figures from Hashrate Index and regional analyses indicate that by October 2025, the country was providing around 14% of the global network’s computing power, placing it in third place behind the United States and Russia. That level is particularly striking given that its share was widely assumed to have fallen to near zero after the 2021 crackdown, suggesting the industry didn’t disappear – it went underground and reorganized.
What stands out most about this resurgence is that the growth in hashrate is concentrated in just a handful of regions. In Xinjiang and other energy-rich areas, low-cost electricity has once again drawn in both individual entrepreneurs and small-scale operators. Despite official restrictions, these regions have become a natural mining ecosystem, thanks to reliable power supply and dense infrastructure.
According to experts, the acceleration seen in global data is not a complete surprise. Even after the ban, China has remained one of the world’s strongest mining centers in terms of hardware manufacturing, logistics and operational know-how. That is why many analysts see the sector’s renewed expansion – long treated as taboo – as a “delayed comeback”, and expect China’s share of the network to grow further heading into 2026.
The Grey Zone: Official Ban, Booming Mining
The most critical reason for China’s comeback in Bitcoin mining is that the industry has been expanding rapidly within a grey economic zone, despite official prohibitions. On paper, crypto mining is still banned nationwide. In practice, the picture is very different. In Xinjiang, Inner Mongolia and Sichuan, where energy production is concentrated, low electricity prices and underused data center capacity have created a powerful magnet for miners.
Operations in these regions rarely present themselves openly as mining farms. Instead, activity is routed through entities labeled as technical consulting firms, data processing facilities or power optimization centers. In many cases, local authorities turn a blind eye. For regional governments, mining functions as an economic lifeline that stabilizes power demand and generates off-the-books side income.
This grey-zone model allows Beijing to keep the mining ban intact on paper, while maintaining a degree of controlled tolerance on the ground. Analysts say it helps absorb surplus energy and smooth out demand across major grids. At the same time, it makes it much harder to assess the true scale of mining inside the country, since most of the activity falls outside official statistics.
Taken together, these dynamics clearly expose the gap between China’s official rhetoric and its practical economic strategy: the ban remains, but mining has never been this lively in the field.
Hardware Front: Canaan and Bitmain Rise Again
The revival of mining activity in China has lifted the country’s two major hardware makers as well. According to industry experts, looser enforcement of the ban has driven significant growth in domestic sales and exports to neighboring countries. The clearest examples are Canaan and Bitmain.
Canaan’s latest financial reports show that domestic Chinese sales, which accounted for only a small slice of revenue in 2022, had grown by 2025 to more than half of the company’s total income. That surge is a strong signal of how fast local demand has come back. Appetite for new-generation ASIC models is being fueled in particular by small and mid-sized miners operating in low-cost regions.
Bitmain, meanwhile, stands out not just for its sales figures but for its geopolitical impact. Its flagship Antminer lineup remains the top choice for both grey-market facilities inside China and large mining farms in neighboring countries. Yet Bitmain’s story doesn’t end with market share. The fact that the United States has placed the company under scrutiny over hardware security and potential cyber risks underscores how central China-based manufacturing has become to the global Bitcoin ecosystem.
The simultaneous rise of Canaan and Bitmain shows that China is not only back on the map in terms of mining capacity – it is still the dominant force in Bitcoin’s hardware ecosystem. The country’s production base and technical expertise are shaping the industry’s trajectory far beyond what its official policies would suggest.
U.S. National Security Concerns: The Bitmain Investigation
China-based mining hardware manufacturer Bitmain is now being discussed not only in the context of Bitcoin’s technical backbone, but also as part of the United States’ national security agenda. Washington has launched a broad investigation into the firm’s widely used Antminer rigs, over concerns about potential hidden access pathways and threats to critical infrastructure. The operation, known as “Operation Red Sunset”, signals that U.S. authorities no longer see crypto mining purely as an economic issue, but as a strategic security matter.
At the heart of the probe are several key questions: whether Antminer models can be remotely controlled over the network, whether their software contains backdoor-like code, and what kind of risks large-scale mining farms might pose to national power grids. As part of the process, some devices have reportedly been dismantled for detailed inspection, while hardware seized by the FCC is being tested at both the physical and firmware levels.
For the U.S., this is not just an investigation into Bitmain. It is a broader reassessment of the supply chain behind global Bitcoin mining. Because Antminer rigs are widely deployed in large American mining farms, any security flaw could, in theory, trigger cascading effects across the country. That reality is pushing crypto mining into a new policy space, at the intersection of energy strategy, cybersecurity and foreign relations.
Experts believe Washington’s stance on Bitmain could eventually extend to other Chinese manufacturers, making geopolitical filters far more important in the mining hardware market. The episode makes one thing clear: even the technical foundations of the Bitcoin network have become part of the great-power competition.
Energy and Climate: China’s Policy Contradictions
China’s renewed strength in Bitcoin mining cannot be explained by economic or technological factors alone. The real debate lies in the glaring contradiction between the country’s official policy narrative and what is happening in the field. The 2021 ban was announced on the grounds of reducing carbon emissions and improving energy efficiency. Yet today, most of the regions where mining is booming still rely on fossil-fuel-heavy power lines.
Low electricity prices in places like Xinjiang and Inner Mongolia are the main factor keeping mining facilities viable. Tied into the country’s heavy industrial corridors, these regions enjoy stable energy supplies. Contrary to official climate messaging, local authorities often view Bitcoin mining as a way to balance the grid, ensure steady consumption and bring extra income into regional economies. That means local practice frequently clashes with central government climate targets.
The resurgence of mining also raises questions about China’s commitment to global carbon goals. Bitcoin mining has long been in the crosshairs of environmental groups because of its energy intensity. By maintaining its official narrative while quietly allowing the mining ecosystem to expand, China is, in the eyes of many analysts, prioritizing economic needs over environmental concerns.
This dual track approach leaves big question marks over the long-term direction of the country’s energy policy. On one hand, Beijing continues to highlight sustainability. On the other, it allows high-consumption sectors like Bitcoin mining to grow quietly in the background. The result is a deeply ambiguous position, both domestically and on the international stage.
Turkmenistan and the New Wave of Regulation
Standing in sharp contrast to China’s grey-market model is a very different approach emerging in the region: Turkmenistan’s open, licensed and transparent mining framework. The country recently passed a comprehensive crypto law that brings Bitcoin mining and exchanges fully under a formal regulatory umbrella. The new regime requires miners to obtain licenses, monitors their energy usage and criminalizes unregistered operations. The aim is to keep production under control, broaden the tax base and ensure that the industry grows under direct state supervision.
This strategy highlights how far Turkmenistan’s path diverges from China’s. While Turkmenistan is setting clear rules and encouraging “legal” growth in mining, China is managing the same sector in a restrictive yet practically tolerant way. In effect, one state is turning mining into an officially sanctioned economic opportunity, while the other is letting a semi-hidden market expand organically in line with its economic needs. The contrast offers a powerful lens on where regional crypto policy might be headed.
Zooming out, the global picture becomes even clearer: Bitcoin mining is no longer a sector that can be understood solely through energy prices or hardware capacity. Governments now treat it as either a strategic revenue stream or a tightly managed risk domain, depending on their priorities. China and Turkmenistan have emerged as emblematic examples of these two extremes.
Ultimately, China’s renewed rise in Bitcoin mining is not just a regional story. It underscores how fragmented global crypto regulation has become. On one side, open licensing regimes are spreading; on the other, grey economies continue to flourish in the shadow of official bans. In this environment, the geographic distribution of Bitcoin’s network is increasingly likely to be shaped by geopolitical decisions, energy policies and security strategies in the years ahead.
