China is a major player in the Bitcoin market, hosting a substantial share of Bitcoin miners (in 2017, it was estimated that 50 to 70 percent of Bitcoin mining took place in the country) and Bitcoin trading volume, although both factors used to be more impressive before a wave of regulatory suppression. At the moment, cryptocurrency trading is prohibited in the country: after the last fall’s crackdown on local exchanges and ICOs, people in China can hold cryptocurrencies, but cannot legally exchange them for fiat money.
