What Is Bitcoin?
Bitcoin is a decentralized digital currency generated through complex computational processes. Introduced in 2008 by an anonymous entity named Satoshi Nakamoto, it operates on a peer-to-peer network where miners solve cryptographic puzzles ("hash functions") to validate transactions and earn rewards. Key features:
- Fixed Supply: Capped at 21 million coins (expected by 2140).
- Decentralization: No central authority controls Bitcoin.
- Volatility: Prices fluctuate based on demand, regulatory news, and market sentiment.

The Rise of Mining Farms in Sichuan’s Mountains
Why Sichuan?
China’s Sichuan province, particularly remote areas like Kangding and Mabian County, has become a global hub for Bitcoin mining due to:
- Abundant Hydropower: Low-cost electricity from local dams fuels energy-intensive mining operations.
- Cool Climate: Natural cooling reduces the need for expensive temperature-control systems.
- Infrastructure: Proximity to hydro stations minimizes power transmission costs.
Inside a Mining Farm
A visit to Tianjia Network’s facility in Mabian revealed:
- 1,500+ ASIC miners operating 24/7 in a deafening 95-decibel environment.
- Daily Output: ~10 BTC (worth ~$200,000 at peak prices).
- Main Challenges: Equipment maintenance, heat dissipation, and ensuring uninterrupted power.
"Where electricity is cheap, we go. Mountains offer low costs, minimal noise complaints, and ideal climates." — Lei Ke, Mining Farm Operator
Economics of Bitcoin Mining
Cost Breakdown
| Expense | Share of Total Cost |
|-----------------|---------------------|
| Electricity | 60–70% |
| Equipment | 20–25% |
| Labor/Maintenance | 10–15% |
Example: Tianjia’s 5,800-machine farm spends 5040元 daily on 168,000 kWh, yielding an annual profit of ~1.84 million元.
Profitability Factors
- Bitcoin Price: A 50% price drop can render mining unprofitable overnight.
- Halving Events: Block rewards halve every 4 years (last in 2020; next in 2024).
- Regulation: Policies like China’s 2021 mining ban forced mass relocations.

FAQs About Bitcoin Mining
Q: How does mining secure the Bitcoin network?
A: Miners validate transactions by solving complex math problems, preventing fraud and ensuring consensus.
Q: Why is most mining concentrated in China?
A: Cheap energy (hydro/coal) and early industry adoption created a competitive advantage.
Q: Can individuals mine Bitcoin at home?
A: Unlikely. Industrial-scale farms dominate due to high hardware and electricity costs.
Q: What’s the environmental impact?
A: Mining consumes massive energy, but Sichuan’s hydropower offers a relatively cleaner option vs. fossil fuels.
The Human Side: A Miner’s Journey
Lei Ke, a former hydroelectric worker, transitioned to Bitcoin mining in 2013. Despite initial family skepticism, he now oversees a thriving operation. His insights:
- Adaptability: Embracing blockchain technology was key to success.
- Regulatory Awareness: Miners closely monitor policies affecting crypto’s legal status.
- Future Vision: "Bitcoin won’t replace fiat but could gain recognition as a commodity."
Conclusion
Sichuan’s mining farms exemplify Bitcoin’s global supply chain—where cutting-edge tech meets rugged landscapes. While profitability hinges on volatile markets and evolving regulations, the industry’s ingenuity ensures its enduring presence.
