According to recent estimates, China accounted for about 14% of Bitcoin’s global hash-rate in late 2025, a slight rise from roughly 13% the prior quarter. Based on reports, that share translates to an estimated slice near 145 EH/s of computing power tied to Chinese influence.
The figure, according to the Fourth Quarter 2025 update of Luxor’s Global Hashrate Map, places China behind two other major contributors and marks a return to a significant role after a sharp decline following policy moves in 2021.
Hardware And Supply Chains
Reports have disclosed that much of the world’s mining rigs are built by Chinese firms. Bitmain, MicroBT and Canaan are still named as the main manufacturers. Because miners around the globe use that gear, the country’s grip on the supply chain remains strong.
Equipment origin, spare parts and technical know-how often trace back to China, and that is one reason why Chinese influence stays visible even when machines run overseas.

Source: Moves After The 2021 Ban Changed Where Rigs Run
In 2021, China ordered a wide crackdown on crypto mining and exchanges. Many large operations left for places like Kazakhstan and the US.
Some groups moved quickly; others split their fleets across borders. Reports say that certain operations continued in hidden forms within China or were run by owners who used overseas subsidiaries. That mix of visible relocation and obscured activity makes it harder to pin down exact shares.
As of today, the market cap of cryptocurrencies stood at $3.71 trillion. Chart: TradingView
Ownership And Hidden Activity
Based on reports, between 55% and 65% of global mining capacity can be linked back to Chinese roots when hardware origin and ownership are counted together.
Early data from 2022 had placed China near 21% in some measures, showing how estimates shift with method and timing. Hashrate snapshots depend on factors such as IP allocation, pool membership and reported ownership.
As a result, different groups produce different country shares, and the numbers should be seen as snapshots rather than fixed totals.
Energy Patterns And Security Concerns
Hydropower in Sichuan and coal in northern regions once helped make Chinese mining cheap. Those energy factors shaped the old geography of mining inside China.
Now that many rigs moved, energy mixes have changed and emissions footprints vary by host country.
