China's crypto crackdown (2021)
China's central bank declared all cryptocurrency transactions illegal, ordering exchanges and mining operations to shut down. The ban came after years of warnings and pushed miners and trading volume out of the country.
Chinese exchanges closed or moved offshore; Bitcoin's price dropped sharply in the weeks after the announcement.
China's mainland remains closed to crypto trading, making it the clearest example of a total ban.
Beijing chose prohibition; Moscow chose licensed integration. Russia's law is the opposite policy answer to the same question about state control over crypto.
