币界网报道:According to Economist, South Korean crypto exchange Coinone won a civil appeal case involving a 2018 system failure that allowed users to repeatedly withdraw Bitcoin. In a ruling issued in May, the Seoul court ordered the relevant users to return all Bitcoin obtained due to the failure. The incident occurred in October 2018, when Bitcoin was traded at about 7.08 million to 7.87 million won (about 5,200 to 5,800 U.S. dollars) against the won on the Coinone exchange, which is about one twentieth of the current value of Bitcoin.
