🇨🇳 Why is Bitcoin mining activity in China experiencing a strong resurgence after 4 years of prohibition?

After the "great ban" in 2021, it seemed that the BTC mining industry had come to an end in China. However, from 2024 to 2025, the country's hashrate unexpectedly rebounded, reclaiming 14-20% of the global network.

Main reasons:

⚡ Cheap & surplus electricity

Provinces like Xinjiang and Sichuan have an excess of coal and hydroelectric power – not fully utilized, so it's used for BTC mining.

🏭 Data centers with excess capacity

Many data centers built too large → excess load → allowing miners to rent at low prices.

💰 BTC price surges from 2024

High prices → improved mining profit margins → activities resume.

🏗️ Canaan mining machine sales increase

From 2.8% of revenue in China (2022) → 50%+ in 2025 → signaling a recovery in mining demand.

🌐 Policy changes

China is no longer "cleanly banned".

– Hong Kong opens a legal framework for stablecoins

– The mainland experiments with e-CNY & RMB stablecoin → moving towards a "selective management" approach.

🧩 Conclusion:

Despite having previously banned it, China remains an energy powerhouse — and BTC “absorbs” that surplus electricity. This return shows that the Bitcoin network continues to adapt, no matter how geopolitical circumstances change.
