In September 2017, Chinese cryptocurrency exchanges BTCC China, Huobi and OKCoin were ordered by the government to shut down their businesses. At one point, executives of the three cryptocurrency exchanges were prevented from leaving the country, due to a government investigation into local cryptocurrency exchanges.
