China’s widening crackdown on bitcoin trading resulted in a travel ban of sorts for two executives from the country’s largest commercial bitcoin exchanges, which regulators are closing down.
At a meeting last week in Beijing, regulators provided bitcoin executives a document saying that the exchanges’ major shareholders, senior managers and key finance and technical personnel should remain in Beijing to work with regulators while unwinding their trading businesses. Huobi and OKCoin spokeswomen didn’t respond to requests for comment.
