The snowmelt from Sichuan’s mountains swells the valley rivers each spring, powering thousands of hydroelectric stations across China’s most water-rich province. In Chengdu—the operational hub of these stations—a different kind of energy is also surging: the relentless hum of cryptocurrency mining rigs. Here, where water meets wires, a new breed of digital prospector thrives—powered by rivers, driven by algorithms, and chasing fortunes written in code.
Meet Yuan Xiao Liu (a pseudonym), a 90s-born engineer turned crypto veteran. Over four years, he transformed from a modest水电 technician into a seven-figure earner in the volatile world of Bitcoin mining. His journey mirrors the rise of Sichuan as China’s unofficial “mining capital”—a story of electricity, ambition, and near-misses with Lamborghinis.
The Power Behind the Protocol
Bitcoin mining isn’t magic—it’s math, heat, and massive power consumption. Miners compete to solve complex cryptographic puzzles; the winner adds a block to the blockchain and earns newly minted coins. The faster your hardware, the higher your odds. But speed demands energy—a lot of it.
Enter Sichuan.
With over 1,000 hydropower stations, the province generates surplus electricity during its May–October wet season. Historically, this excess power was wasted—literally spilled through open dams. Then came the miners.

In 2016, Yuan’s company took a gamble: lease idle hydroelectric capacity to crypto miners. The results were staggering. A single site drawing 50,000 kWh per hour could generate over **$300,000 monthly** at just $0.03/kWh. Investment in transformers and cooling systems paid for itself in under two months during bull markets.
China once controlled 70% of global Bitcoin hash rate, with Sichuan alone accounting for 70% of that. The synergy was perfect: Shenzhen built the machines; Sichuan powered them.
From Host to Hunter: The Rise of a Miner
Yuan didn’t stay a passive landlord. By 2019, he’d dipped into mining himself—buying Antminer S9s and joining mining pools.
But crypto wealth comes with hidden costs:
- Malware attacks: Some “free antivirus” tools secretly siphoned off 5–10% of miners’ computing power.
- Brutal working conditions: Noise levels exceed 100 decibels—equivalent to a chainsaw—requiring staff to wear ear protection. Heat output demands industrial fans (1,500W each), yet rapid airflow prevents sweat evaporation, making the environment feel hotter.
- Labor retention: Monthly salaries often exceed $1,400 to keep skilled operators on-site.
Still, returns were undeniable. After one season, Yuan netted nearly $70,000—enough to cover startup costs and fund further expansion.
Then came the decision that still haunts him.
The $1 Million Mistake
In late 2020, with Bitcoin hovering around $18,000**, Yuan needed cash for his wife’s business. Believing prices would plateau, he sold **2,000 S9 miners** at scrap value—**$13 each—recouping about $26,000.
Months later, Bitcoin soared past $60,000.
The same miners? Resold for nearly $275 each**—a **2,000% increase**. That $26k could have been over half a million dollars**.
“I don’t regret it,” Yuan says. “I made over a million that year. But yes—I saw someone buy a Lamborghini with what I sold as e-waste.”
That buyer? A former acquaintance who purchased the rigs cheaply and cashed out during the peak. One night at Chengdu’s Play House club, he dropped $28,500 on a VIP membership—paid in full on the spot.
“The market rewards patience—and punishes fear,” Yuan reflects. “But not everyone can hold through the storms.”
Mining in the Age of Scarcity
Today, mining has evolved into a high-stakes supply chain war.
- Hardware shortages: Due to chip shortages and soaring demand, miners now buy rigs on futures contracts. Yuan recently placed a $430,000 deposit for Avalon miners—delivery expected in May.
- Price inflation: Antminer S19 models that cost $15,000** in 2020 now sell for over **$65,000, with waitlists stretching into November.
- GPU mania: NVIDIA’s RTX 3060, originally priced at $450**, now trades near **$850 after miners bypassed its Ethereum mining limiter.
“Last year’s best financial product wasn’t stocks or real estate,” Yuan jokes. “It was a graphics card.”
Why Sichuan Still Matters
Despite crackdowns in Inner Mongolia and Xinjiang pushing miners westward, Sichuan remains competitive—not just for price, but for stability.
- Electricity rates have dropped from $0.035/kWh in 2017 to $0.022/kWh in 2025.
- Operators now require only half-month deposits, down from full-month prepayments.
- The provincial government officially recognized crypto mining under its Hydropower Consumption Demonstration Zone initiative in 2019—listing several mining farms as approved enterprises.
Yet global alternatives are emerging: Kazakhstan’s coal-powered plants, Russian hydro sites, even U.S. nuclear-backed facilities offer sub-$0.02/kWh rates.
“Cheap power isn’t enough,” Yuan insists. “You need reliable operations, skilled engineers, and secure infrastructure. That’s our edge.”

The Human Cost of Digital Gold
Crypto doesn’t forgive mistakes—or leverage.
- In 2019, BitYi founder Hui Yi died by suicide after a 100x leveraged bet collapsed.
- A Dalian trader lost $2 million, then killed his daughter before jumping into the sea with his wife in 2020.
“Leverage is poison,” Yuan warns. “This market will break you if you’re greedy.”
Yet others have won big through patience. A friend who accepted two BTC as payment in 2017 (then worth ~$20k) now holds assets worth over **$140,000**—enough for a down payment in Chengdu.
FAQs: Inside the Mind of a Miner
Q: Is Bitcoin mining still profitable in 2025?
A: Yes—but margins are tight. Profitability depends on electricity cost (<$0.03/kWh ideal), hardware efficiency (e.g., Antminer S19 XP), and sustained network difficulty.
Q: Can individuals still mine profitably?
A: Solo mining is nearly impossible. Most join mining pools to combine hash power and share rewards proportionally.
Q: What happens when all 21 million Bitcoins are mined?
A: Miners will rely solely on transaction fees. Current estimates suggest full mining completion by 2140.
Q: How do halving events affect miners?
A: Every four years, block rewards are cut in half (last event: May 2024). This reduces income unless price rises to compensate—increasing pressure on inefficient operators.
Q: Is green mining sustainable long-term?
A: When powered by surplus renewables like Sichuan’s hydropower, yes. It turns otherwise wasted energy into economic value without additional carbon cost.
Q: Could another country replace China’s mining dominance?
A: No single nation currently matches China’s combination of infrastructure, technical talent, and energy scale. However, North America and Central Asia are gaining share rapidly.
The Future Is Mined
For Yuan, crypto is more than profit—it’s legacy. As his wife prepares to give birth, he plans to gift their child the first Bitcoin he mines this season.
“I’ll give it to them when they turn 21 or get married,” he says. “Elon said Bitcoin could hit $1 million by then. I’ll take that bet.”
As spring flows into summer and rivers roar to life, so too will the machines—spinning electricity into digital gold. In Chengdu’s underground server rooms, amid deafening fans and flickering LEDs, the next chapter of financial revolution hums quietly along.
And somewhere beneath the noise, a new generation’s inheritance is being forged—one hash at a time.
