The Geography of Mining: China to Global

For most of Bitcoin's history, China was the undisputed center of mining. The reasons were straightforward: China had the cheapest electricity in the world for industrial users, particularly in Sichuan and Yunnan provinces, where abundant hydroelectric dams produced power at rates as low as $0.01–$0.03 per kWh during the wet season (May–October). During the dry season, miners migrated equipment to coal-rich northern provinces like Inner Mongolia and Xinjiang, where thermal power was also cheap.

China also benefited from being home to the world's largest ASIC manufacturers. Bitmain (Beijing/Shenzhen), MicroBT (Shenzhen), and Canaan (Hangzhou) designed and manufactured the mining hardware, meaning Chinese miners had first access to new equipment with lower shipping costs. An entire ecosystem of mining farms, hosting services, and equipment dealers developed across the country. By early 2021, the Cambridge Centre for Alternative Finance estimated that 65–75% of global Bitcoin hash rate was located in China.

In May 2021, China's State Council announced a crackdown on Bitcoin mining and trading as part of broader efforts to control financial risk and meet carbon reduction targets. Provincial governments moved quickly: Inner Mongolia banned mining in March 2021, followed by Qinghai, Xinjiang, Sichuan, and Yunnan through May and June. Miners were given days to weeks to shut down operations.

What followed was the largest forced migration of computing infrastructure in history. Hundreds of thousands of ASIC miners — each weighing 10–15 kg and valued at $5,000–$10,000 — were shipped out of China by truck, plane, and container ship. Some miners sold equipment at fire-sale prices. Others arranged hosting contracts in Kazakhstan, the United States, Russia, and Canada before even receiving their machines. The logistics were staggering: chartering cargo flights, negotiating with customs officials, finding warehouse space and electrical capacity in countries that had never hosted mining at this scale.

The post-ban world looks fundamentally different. The United States emerged as the world's largest mining country, hosting an estimated 35–40% of global hash rate by 2023. Texas became the epicenter, offering deregulated electricity markets, cheap natural gas, abundant wind and solar capacity, and a pro-business regulatory environment. Companies like Riot Platforms (Rockdale, TX), Marathon Digital (multiple sites), and Core Scientific built massive facilities across the state. Georgia, New York, Wyoming, and North Dakota also attracted significant mining operations.

Kazakhstan initially absorbed a large share of displaced Chinese miners, briefly becoming the world's second-largest mining country at roughly 18% of global hash rate by August 2021. However, the country's aging electrical grid couldn't support the sudden demand increase, leading to blackouts and a government crackdown of its own in 2022. Russia became another major destination, with miners setting up in Siberia and other regions with cheap hydroelectric power, though Western sanctions complicated the picture after 2022.

The net effect of the China ban was a dramatic improvement in Bitcoin mining's geographic decentralization. Before the ban, a single country controlled two-thirds of hash rate. Afterward, no country controls more than 40%, and mining operations span every inhabited continent. New mining hubs have emerged in unexpected places: Paraguay (cheap Itaipu Dam hydropower), the United Arab Emirates (sovereign wealth fund investments), Bhutan (government-run hydroelectric mining), and Ethiopia (Grand Renaissance Dam power).

This geographic diversification strengthens Bitcoin's resistance to regulatory risk. No single government can significantly impair the network by banning mining within its borders — as China demonstrated, miners simply relocate. The trend toward distributed mining aligns with Bitcoin's core design philosophy: a network that is resilient because it has no single point of failure. As more countries recognize mining as a legitimate industry and compete for the economic activity it generates, the geographic distribution is likely to continue broadening, making Bitcoin's infrastructure increasingly robust against political disruption.
