For over a decade, Bitcoin mining transformed remote corners of China into digital gold rush zones—especially in Sichuan, where abundant hydropower and mountainous terrain created ideal conditions for energy-hungry operations. But today, the era of easy profits is long gone. What was once seen as a path to overnight wealth has become a high-stakes gamble, with miners now struggling to break even amid falling Bitcoin prices, rising costs, and tightening regulations.
This deep dive explores the evolution of Bitcoin mining in China, focusing on real-life experiences from the field—from isolated mountain “mining farms” to the economic realities shaping the future of this controversial industry.
The Rise of Sichuan as the "Mining Capital"
Nicknamed the “World Mining Capital,” Sichuan earned its title not through traditional minerals, but through its dominance in Bitcoin production. Thanks to seasonal hydropower surpluses—particularly during summer months—the region offered some of the cheapest electricity in the world, making it a magnet for large-scale mining operations.
Hydropower plants along rivers like the Dadu and Yalong generate massive amounts of electricity. However, due to insufficient transmission infrastructure, much of this energy would otherwise go unused—dubbed “stranded” or “wasted” power. Enter Bitcoin miners: they provided an instant market for this excess supply.

Mining facilities sprang up near dams and substations, often housed in simple prefabricated metal buildings. These remote outposts, tucked into valleys and accessible only by winding mountain roads, became hubs of digital currency creation—powered entirely by renewable energy.
Life Inside a Remote Mining Farm
For workers like Shi Lei (a pseudonym), life at a mining farm is far from glamorous. Once a网吧 (internet cafe) manager in Chongqing, he took a job maintaining mining hardware in a remote Sichuan facility after being recruited by a relative.
The reality? Isolation. Routine. Exhaustion.
Located deep in western Sichuan’s highlands, the facility operates 24/7. Rows of industrial fans roar constantly to cool thousands of ASIC miners—specialized machines designed solely to solve complex cryptographic puzzles and earn Bitcoin rewards.
Shi’s daily tasks include cleaning dust from machines using industrial blowers, monitoring temperatures, and fixing network disconnections caused by heat or power fluctuations. He patrols the server room every hour—day and night.
“There’s nothing to spend money on here,” Shi admits. “No shops, no entertainment. Just mountains, snow, and machines. It’s not a life for young people.”
How Bitcoin Mining Actually Works
At its core, Bitcoin mining is a decentralized process where computers compete to validate transactions and add them to the blockchain. Miners solve cryptographic challenges; the first to succeed earns newly minted Bitcoin as a reward.
In Bitcoin’s early days (pre-2012), even standard CPUs could mine profitably. But as adoption grew, so did competition—and difficulty.
Today, mining requires Application-Specific Integrated Circuit (ASIC) chips, such as those found in Bitmain’s Antminer S9. These devices are incredibly powerful—and power-hungry. A single S9 consumes about 1,800 watts per hour, translating to roughly 43 kWh per day.
With electricity accounting for over 70% of operational costs, location is everything. That’s why miners follow cheap energy: south to Sichuan in summer for hydropower, north to Xinjiang in winter for surplus coal-based electricity.
But this migratory lifestyle is changing.
The Economic Reality: Mining Is Now Unprofitable
For many operators, mining no longer makes financial sense.
Take Zhang, a miner who owns around 10,000 Antminer S9 units across several farms. At current Bitcoin prices (~$6,400 as of late 2018), his operation is losing money.
Here’s a simplified breakdown:
- Daily output per S9: ~0.0005 BTC (~$3.20)
- Monthly revenue per machine: ~$96
- Monthly cost per machine (electricity, depreciation, maintenance): ~$137
- Net loss per machine: ~$41/month
That means Zhang loses $410,000 per month across 10,000 machines.
And it’s not just him. Industry-wide, older models like the S9 are hitting “shutdown prices”—the point at which continuing operation costs more than stopping does.
Even newer models struggle as Bitcoin’s price remains volatile and block rewards halve periodically—a built-in deflation mechanism.
Regulatory Pressure Mounts
Beyond market forces, miners face growing scrutiny from authorities.
While China has not outright banned mining, regulators have cracked down on associated risks:
- No tax contributions
- Environmental concerns
- Fire hazards from overloaded circuits
- Noise and heat pollution
- Unlicensed operations
Local governments have proposed charging “management fees” of $24/month per machine—an added burden for already-struggling operators.
A government official in western Sichuan stated: “These farms bring no jobs, no taxes, no real economic benefit. They only create safety risks.”
Meanwhile, national policy labels cryptocurrency mining as a form of “pseudofinancial innovation” that deviates from real economic activity. Authorities are using tools like electricity pricing and land use restrictions to encourage orderly exit.
Regions like Xinjiang and Inner Mongolia have begun shutting down illegal mining operations.
From Boom to Bust: Lessons from the Crypto Cycle
Bitcoin’s journey—from near-zero value in 2008 to nearly $20,000 in 2017—created legends of wealth. But for every success story, there are tales of loss.
Wang Cong (a pseudonym), a former software engineer from Chengdu, bought Bitcoin in 2013 for 6,000 RMB (~$950). After a brief spike, he watched it crash to 200 RMB following regulatory warnings against third-party payment support for exchanges.
He held on. By 2016, prices rebounded. By late 2017, he sold at the peak—becoming a millionaire overnight.
“Crypto time moves faster than real life,” he says. “A day in the crypto world feels like a year elsewhere.”
But timing is everything. Those who bought at the top and held through the crash faced devastating losses.
FAQ: Understanding Today’s Mining Landscape
Q: Is Bitcoin mining still profitable in China?
A: For most operators using older hardware like the Antminer S9, mining is currently unprofitable due to low Bitcoin prices and high electricity and maintenance costs.
Q: Why did Sichuan become a mining hub?
A: Abundant hydropower during summer months provides cheap electricity—critical since energy makes up over 70% of mining costs.
Q: Are Bitcoin miners damaging the environment?
A: While mining itself doesn’t emit carbon directly, its massive energy consumption raises sustainability concerns—though much of Sichuan’s mining uses otherwise-wasted hydropower.
Q: Can individuals still mine Bitcoin at home?
A: Not practically. Modern mining requires specialized ASIC hardware and access to cheap electricity—far beyond what residential setups can support.
Q: What happens when miners shut down?
A: Reduced mining activity temporarily lowers network difficulty, potentially improving profitability for remaining miners—until prices or costs shift again.
Q: Will Bitcoin mining return to profitability?
A: It depends on future price movements, technological improvements, and regulatory developments. Many believe consolidation and efficiency gains will shape the next phase.

The Future of Mining: Consolidation and Adaptation
As small players exit, larger firms with better access to capital and energy resources are positioning themselves for long-term survival. Some are investing in more efficient chips or exploring green energy partnerships.
Meanwhile, companies like Bitmain—once solely focused on ASICs—are diversifying into AI and edge computing to reduce reliance on crypto cycles.
The dream of fast riches has faded. In its place is a harsher reality: Bitcoin mining is now a capital-intensive, highly competitive industry where survival depends on efficiency—not speculation.

Conclusion: The End of an Era?
The golden age of Bitcoin mining in China may be over—but its legacy endures. From transforming remote hydropower stations into global crypto nodes to fueling debates about technology, regulation, and sustainability, mining has left an indelible mark.
Today’s miners aren’t chasing dreams—they’re managing losses. Yet amid the noise and heat of these mountain server rooms lies a powerful truth: behind every digital coin is real-world infrastructure, human effort, and economic consequence.
As markets evolve and regulations tighten, one thing is clear—the wild west days of crypto are giving way to a more mature—and far less forgiving—industry.
