Bitcoin Ban China: What Happened and How It Changed Crypto Globally

When Bitcoin ban China, China’s 2021 crackdown on cryptocurrency mining and trading that forced over 70% of global Bitcoin mining offline. Also known as China’s crypto crackdown, it wasn’t just a policy shift—it was a seismic event that rerouted the entire crypto ecosystem. Before 2021, China controlled most of the world’s Bitcoin mining power. Farms in Sichuan and Inner Mongolia ran on cheap hydropower, turning the country into the backbone of Bitcoin’s security. Then, overnight, the government shut it all down. No warning. No transition. Just a ban on mining, trading, and even crypto-related advertising. The result? A global scramble.

The crypto mining ban, China’s decision to outlaw cryptocurrency mining operations due to energy consumption and financial control concerns. Also known as mining prohibition, it forced miners to flee—some to Kazakhstan, others to the U.S., and many to places like Norway and Canada, where energy was clean and regulations were clearer.

You’ll find posts here that dive into how miners relocated, how exchanges adapted, and how China’s move inspired similar actions in other countries—from Nigeria to Norway. These aren’t just stories about policy. They’re about survival, innovation, and what happens when a government tries to control money that doesn’t need permission to exist.
