In the remote, misty highlands of Sichuan, a quiet technological revolution hums behind the roar of rushing rivers and spinning turbines. Deep within the valleys of Maqin Yi Autonomous County, thousands of specialized computers—known as Bitcoin mining rigs—operate nonstop, converting surplus hydropower into digital currency. This is the heart of China’s decentralized computing frontier, where rugged terrain meets cutting-edge blockchain technology.
The Hidden World of Bitcoin Mining Farms
Bitcoin mining is the engine that powers the world’s first decentralized cryptocurrency. Miners use powerful hardware to solve complex cryptographic puzzles—known as "hashing"—to validate transactions and earn newly minted Bitcoin as a reward. This process, called "proof of work," demands immense computational power and, consequently, vast amounts of electricity.
To keep costs low, miners seek regions with abundant, affordable energy. That’s how the mountainous regions of Sichuan—rich in hydropower—became a global hotspot for Bitcoin mining operations.

Inside a Mountain Mining Facility
Tucked beside the tributaries of the Dadu River lies one of the largest Bitcoin mining sites operated by Tianjia Network Technology Co., Ltd. Reaching it requires a grueling three-and-a-half-hour drive from Leshan, navigating narrow, muddy mountain roads passable only by high-clearance vehicles.
Inside the facility, noise levels reach 95 decibels—the equivalent of standing near a jet engine. Over 1,500 ASIC (Application-Specific Integrated Circuit) miners run 24/7, their fans creating a wind tunnel effect to dissipate heat. Each machine is meticulously positioned to optimize airflow and prevent overheating.
“Each day, this single room generates nearly 10 Bitcoins,” shouts Lei Ke, operations supervisor at the site. Communication is difficult due to the constant drone, but the team remains vigilant—checking systems hourly for malfunctions or thermal issues.
Just 200 meters away, the tranquil Mayi River flows through lush forests. Nearby, children from a local Yi ethnic minority school play on dirt paths, unaware that their quiet village powers part of the global blockchain network.
Why Sichuan? The Economics of Energy and Efficiency
The answer lies in energy economics. Bitcoin mining consumes approximately 0.5% to 1% of global electricity—making power cost the single largest operational expense.
In cities like Beijing or Shanghai, industrial electricity prices can exceed ¥1 per kilowatt-hour. In contrast, during Sichuan’s rainy season (May to October), surplus hydropower drives prices down to as low as ¥0.2–0.3/kWh—sometimes even lower through direct agreements with small hydropower stations.
This seasonal abundance gave rise to what industry insiders call the “Bao Er Ye theory”—named after a well-known crypto advocate who popularized the idea: Why let clean energy go to waste when it can be turned into digital gold?
The concept sparked a wave of migration. Entrepreneurs began mapping small hydropower stations across Southwest China, negotiating leases and setting up mining farms directly on-site to avoid transmission losses and reduce infrastructure costs.
By 2015, Sichuan had become China’s top market for mining hardware sales, capturing nearly 30% of national volume. Today, cities like Kangding host over 20 mining operations and even serve as global repair hubs for major mining equipment manufacturers.
From Graphics Cards to Industrial-Scale Farms
Bitcoin mining has evolved dramatically since its early days.
In the beginning, enthusiasts used standard GPUs (graphics processing units) at home. But with residential electricity rates and slow processing speeds, many found themselves spending more on power than they earned in Bitcoin—often burning out their hardware in the process.
As competition grew, miners shifted toward centralized, industrial-scale operations. Specialized ASIC miners offered exponentially higher hash rates with improved efficiency. Economies of scale made large farms more profitable than scattered individual setups.
Now, an estimated 70% of global Bitcoin hash rate originates from China, with Sichuan, Xinjiang, Inner Mongolia, and Ningxia serving as key hubs—each leveraging regional energy advantages: hydropower in summer, coal or wind in winter.
The Seasonal Migration of Miners
Operating in Sichuan comes with a unique challenge: seasonality.
During the wet months (May–October), rivers swell and hydroelectric output peaks—providing cheap, clean power ideal for mining. But come winter, water levels drop sharply. Power becomes scarce and expensive—sometimes doubling in price.
To adapt, many mining operators engage in what’s known as “mining migration.” Like nomadic beekeepers chasing blooms, they pack up thousands of machines and relocate them to northern regions such as Xinjiang and Inner Mongolia, where coal-powered plants offer stable winter electricity.
This annual cycle involves logistical risks: transporting sensitive electronics over dangerous mountain roads prone to landslides and flash floods. Accidents are not uncommon.
However, some operators—like Tianjia Network—avoid migration altogether by partnering with hydropower stations whose output consistently meets their needs year-round.

Community Impact: From Outsiders to Enthusiasts
The arrival of mining farms has subtly transformed local communities.
Residents who once knew nothing about blockchain now follow Bitcoin prices daily. Some have even set up personal mining rigs at home—earning modest but meaningful income. One local resident shared: “I run a small miner at home. It makes about ¥2 a day—but it’s something.”
Moreover, interest in financial technology has grown. Locals discuss blockchain developments, coding basics, and central bank regulations with surprising fluency—aware that policy shifts in Beijing can instantly affect their earnings.
In nearby Chengdu, Bitcoin meetups and mining conferences now draw attendees from government investment agencies, small power stations, and tech startups—fostering an emerging ecosystem around digital assets.
Frequently Asked Questions
Q: Why do Bitcoin miners choose remote areas like Sichuan?
A: Miners prioritize low electricity costs and cooler climates. Sichuan’s abundant hydropower during the rainy season offers some of the cheapest energy in the country—making it ideal for energy-intensive mining operations.
Q: How does seasonal change affect Bitcoin mining in China?
A: During summer (May–October), miners rely on cheap hydropower in Southwest China. In winter, they often relocate equipment to coal-rich northern regions like Xinjiang and Inner Mongolia to maintain profitability.
Q: Is Bitcoin mining still profitable in 2025?
A: Yes—but only at scale and with low-cost power. Profitability depends on electricity prices, hardware efficiency, and Bitcoin’s market price. Industrial farms in regions with sub-¥0.3/kWh power remain competitive.
Q: What role does China play in global Bitcoin mining?
A: Despite regulatory scrutiny, China has historically hosted up to 70% of global Bitcoin hash rate due to its access to cheap energy and manufacturing capacity for mining hardware.
Q: Are there environmental concerns with Bitcoin mining?
A: While energy consumption is high, much of China’s mining relies on renewable hydropower during peak seasons. Some operators argue that using otherwise-wasted surplus energy reduces waste and carbon impact.
Q: Can individuals still mine Bitcoin profitably?
A: Solo GPU mining is no longer viable. However, individuals can join cloud mining platforms or pool-based networks to participate indirectly—with lower barriers to entry.
The Future of Mining in a Changing Landscape
As global interest in digital currencies grows, so does scrutiny on energy use and decentralization. Yet in places like Sichuan, Bitcoin mining persists—not as a speculative fad, but as an adaptive industry built on geography, engineering, and economic pragmatism.
While regulatory shifts may alter operational models, the core principle remains unchanged: wherever cheap, reliable power exists, miners will follow.
Whether nestled beside roaring rivers or powered by desert wind farms, the pursuit of digital value continues—one hash at a time.
