China’s Bitcoin Mining Isn’t Dead — It’s The World’s No. 3 Contributor

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 ￰0￱ on reports, that share translates to an estimated slice near 145 EH/s of computing power tied to Chinese ￰1￱ 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 ￰2￱ 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 ￰3￱ miners around the globe use that gear, the country’s grip on the supply chain remains ￰4￱ 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 ￰5￱ After The 2021 Ban Changed Where Rigs Run In 2021, China ordered a wide crackdown on crypto mining and ￰6￱ large operations left for places like Kazakhstan and the ￰7￱ groups moved quickly; others split their fleets across ￰8￱ say that certain operations continued in hidden forms within China or were run by owners who used overseas ￰9￱ mix of visible relocation and obscured activity makes it harder to pin down exact ￰10￱ 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 ￰11￱ data from 2022 had placed China near 21% in some measures, showing how estimates shift with method and ￰12￱ snapshots depend on factors such as IP allocation, pool membership and reported ￰13￱ a result, different groups produce different country shares, and the numbers should be seen as snapshots rather than fixed ￰14￱ Patterns And Security Concerns Hydropower in Sichuan and coal in northern regions once helped make Chinese mining ￰15￱ energy factors shaped the old geography of mining inside ￰16￱ that many rigs moved, energy mixes have changed and emissions footprints vary by host ￰17￱ image from Pixabay, chart from TradingView
