The Japanese cryptocurrency exchange DMM Bitcoin reported that a breach cost it 48 billion yen ($305 million) in bitcoin (BTC).4,502.9 BTC “leaked” out of the exchange, according to a blog post by DMM Bitcoin on its website. To prevent more unapproved outflows, precautions have been taken.
“Please be assured that we will procure the equivalent amount of BTC equivalent to the outflow with the support of the group companies and guarantee the full amount,” DMM Bitcoin said.
Exchange officials have announced that all spot buys on the platform will be prohibited and that withdrawals of Japanese yen “may take more time than usual.” This is the region’s second-largest loss. In 2018, 58 billion yen were stolen from Coincheck.
