Catenaa, Saturday, July 12, 2025- Despite a 2021 ban on crypto mining, between 55% and 65% of global Bitcoin mining operations still trace their origins to China through capital, hardware, or technical expertise, according to Batyr Hydyrov, CEO of mining equipment supplier Uminers.
The world’s three largest Bitcoin mining hardware manufacturers like Bitmain, Canaan, and MicroBT, all Chinese firms, are expanding US operations to avoid tariffs imposed by former President Donald Trump.
Together, they produce 99% of Bitcoin’s mining hardware, application-specific integrated circuits, or ASICs.
Following China’s mining ban, the US has surged from 4% to 38% of the global Bitcoin hashrate. Still, many major players with Chinese roots relocated to countries including the US and Russia, continuing and often expanding operations.
Hydyrov said some mining continues inside China, mainly in less regulated provinces using renewable energy, with firms offering heat recovery to local governments.
Larger miners shifted abroad, with firms moving rigs from Xinjiang to Kazakhstan or setting up production in the US
Trump has emphasized Bitcoin’s role in US economic strategy, aiming to challenge China’s dominance. His sons launched American Bitcoin, raising \$220 million to expand mining operations.
Experts say fully decoupling from Chinese mining technology will take years due to the need for investment, expertise, and supply chain development. The US is training specialists but remains dependent on Chinese-made equipment and consultants for now.
