Japanese crypto exchange DMM Bitcoin is shutting down after hackers stole 4,502 Bitcoin (BTC) valued at about $305 million U.S. at the time the theft occurred in May of this year.
DMM Bitcoin said it plans to transfer all its accounts and assets to trading platform SBI VC Trade by March of next year.
DMM Bitcoin had restricted services such as withdrawals and the acceptance of purchase orders for spot cryptocurrency assets since the hack occurred last spring.
However, the crypto exchange said it can no longer continue to operate in its current state as it would impair its current customers.
“We sincerely apologize for the inconvenience caused over such a long period of time,” said the exchange in a written statement.
Who hacked DMM Bitcoin and stole the crypto is not known. Although speculation online is that it was North Korean cyberhackers the Lazarus Group.
Money from the hack appears to have passed through Huione Guarantee, a Cambodian payments company that has enabled the laundering of billions in illegal funds over the years.
Bitcoin is currently trading at $95,600 U.S., having risen 116% this year.
