In recent years, the world has witnessed a dramatic surge in interest around bitcoin mining, a digital process that powers one of the most revolutionary financial innovations of the 21st century. While many envision cryptocurrency as a product of sleek tech hubs and Silicon Valley startups, the reality is far more rugged—especially when it comes to where most bitcoins are actually created.
A revealing investigation by China Central Television (CCTV) uncovered a surprising truth: approximately 70% of the world’s bitcoin is mined within China, primarily in remote mountainous regions like the high-altitude plateaus of western Sichuan. These hidden facilities, often powered by surplus hydropower, operate at massive scale—generating not only digital wealth but also raising critical questions about energy use, regulation, and the future of decentralized finance.
The Hidden World of Bitcoin Mining Farms
Tucked away in the remote valleys of Sichuan, at elevations exceeding 4,000 meters, lie industrial-sized bitcoin mining farms. These are not traditional factories but vast server rooms packed with thousands of specialized computers—known as mining rigs—running 24/7 to solve complex cryptographic puzzles.
Each "mining rig" is essentially a high-performance machine designed for one purpose: validating transactions on the Bitcoin blockchain and earning newly minted bitcoins as a reward. The process, known as proof-of-work, requires immense computational power—and even more electricity.
One medium-sized facility visited by reporters housed around 5,000 mining machines. With industrial fans roaring to cool down overheating hardware, the noise level was deafening. According to the owner, Wang Ruixi, this single site produces over 16 bitcoins per day—worth more than $300,000 at current market rates.
Why China Dominates Global Bitcoin Mining
The dominance of Chinese mining operations isn’t accidental. Several key factors converge to make certain regions in China uniquely suited for large-scale bitcoin mining:
1. Abundant and Low-Cost Hydropower
Electricity accounts for up to 50% of mining costs, making cheap power essential for profitability. In Sichuan and other provinces like Yunnan and Xinjiang, abundant hydropower during the rainy season creates an energy surplus. Some small hydropower stations, unable to feed excess electricity into the national grid, have struck direct deals with miners.
These off-grid arrangements allow miners to access electricity at rates as low as $0.03–$0.05 per kWh, less than half the standard industrial rate in most parts of China.
“We’re not connected to the state grid,” explained one miner. “The power comes straight from a nearby hydro station. It’s like we’re partners—them providing energy, us providing machines.”
However, such setups may violate regulations. State-owned grid companies confirm that direct private sales of electricity bypass official monitoring systems and are technically illegal.
2. Favorable Climate for Cooling
High-performance mining rigs generate tremendous heat. In warmer climates, cooling becomes a major expense. But in high-altitude areas like Kangding and Aba Prefecture, naturally cool temperatures reduce reliance on artificial cooling systems—further lowering operational costs.
3. Domestic Manufacturing Ecosystem
China leads the world in manufacturing ASIC mining hardware, the specialized chips used in bitcoin mining. Companies like Bitmain dominate global supply chains, giving domestic miners faster access to cutting-edge equipment.
As a result, local entrepreneurs can scale operations rapidly. One sales agent reported selling nearly 1,000 units per day, with annual revenues reaching $100 million across 300,000 machines sold nationwide.

The Rise of a New Digital Economy
Bitcoin mining has evolved from a niche hobby into a full-fledged industry. Young entrepreneurs in their twenties now run multi-million-dollar mining empires. Some reinvest profits into expanding their farms; others cash out periodically on cryptocurrency exchanges.
Interestingly, demand isn’t limited to domestic investors. Foreign buyers increasingly purchase Chinese-made mining rigs—some shipping them overseas, while others opt for mining machine托管 (hosting services) in China due to lower electricity costs.
One vendor noted that international clients account for about 30% of total sales, highlighting China’s central role in the global crypto infrastructure ecosystem.
Regulatory Challenges and Legal Gray Areas
Despite its economic impact, bitcoin mining exists in a complex legal environment.
Is Bitcoin Mining Legal?
China does not recognize bitcoin as legal tender. However, it classifies it as a virtual commodity, meaning ownership and mining are not outright banned—at least not yet.
According to Professor Li Aijun, Director of the Internet Finance Research Institute at China University of Political Science and Law:
“Bitcoin is treated as a special kind of virtual product. If you produce it with the intent to sell or trade, then it should be subject to taxation and fall under commercial supervision.”
Yet enforcement remains inconsistent. Many miners claim they don’t pay taxes because they view mining as “playing a game” rather than running a business.
Who Should Regulate Crypto Activities?
There’s no single regulatory body overseeing bitcoin mining or trading. Different risks point to different authorities:
- Anti-money laundering (AML) concerns → Central Bank oversight
- Tax compliance → Taxation authorities
- Energy usage and grid violations → Power regulatory agencies
Without clear jurisdiction, enforcement is patchy—and many operations continue unchecked.
Frequently Asked Questions (FAQ)
Q: What percentage of global bitcoin is mined in China?
A: Industry estimates suggest around 70%, largely concentrated in Sichuan, Yunnan, Inner Mongolia, and Xinjiang due to favorable energy conditions.
Q: How much electricity does a typical mining farm consume?
A: A mid-sized farm with 5,000 rigs can use over 60 million kWh annually—equivalent to the yearly consumption of a small town with 100,000 residents.
Q: Are bitcoin miners required to pay taxes in China?
A: Legally, if mining is conducted as a commercial activity with profit intent, it should be taxable. However, compliance is low due to regulatory ambiguity.
Q: Is bitcoin mining environmentally sustainable?
A: While hydropower reduces carbon emissions compared to coal-based grids, the overall energy footprint remains massive. Sustainability depends on long-term energy sourcing and technological efficiency.
Q: Can individuals still profit from mining at home?
A: For most people, solo mining is no longer viable due to high hardware and electricity costs. Pool mining or cloud-based solutions offer better returns for small-scale participants.
Q: Will China ban bitcoin mining completely?
A: While there have been crackdowns on exchange trading and initial coin offerings (ICOs), mining has not been explicitly outlawed nationwide—but localized restrictions do exist.

The Future of Bitcoin Mining in China
As global interest in blockchain grows, so too does scrutiny over how and where cryptocurrencies are produced. China’s current dominance in mining reflects its strengths in energy production, hardware manufacturing, and entrepreneurial agility.
But this leadership position faces challenges:
- Increasing pressure to regulate off-grid power usage
- Potential environmental concerns over energy consumption
- Global shifts toward greener alternatives like proof-of-stake consensus models
Still, for now, the hum of servers deep in Sichuan’s mountains continues—a testament to how a decentralized digital currency has become deeply rooted in one of the most unexpected physical landscapes on Earth.
