Mt. Gox
Mt. Gox suspended withdrawals in US dollars on 20 June 2013. The Mizuho Bank branch in Tokyo that handled Mt. Gox transactions pressured Mt. Gox from then on to close its account. On 4 July 2013, Mt. Gox announced that it had "fully resumed" withdrawals, but as of 5 September 2013, few US dollar withdrawals had been successfully completed.
