Japanese authorities began investigating Mt. Gox, the Tokyo-based Bitcoin exchange that shut down this week, amid calls for regulation of the digital currency as customers face losses.
The Financial Services Agency, Finance Ministry and police are examining the closure of Mt. Gox, Chief Cabinet Secretary Yoshihide Suga said today. Officials from the FSA, the ministry and the Bank of Japan said they didn’t have responsibility for overseeing Bitcoin. Mt. Gox has been subpoenaed by U.S. prosecutors, the Wall Street Journal reported.
