Japanese cryptocurrency exchange DMM Bitcoin has decided to liquidate its operations following a major hack that saw $320 million in Bitcoin stolen. The company plans to transfer customer assets to SBI VC Trade, amid ongoing investigations and regulatory pressures.
DMM Bitcoin Suffers Major Loss
In late May, DMM Bitcoin experienced a significant breach resulting in the theft of over 4,500 Bitcoins from one of its wallets. The vulnerability was linked to flaws in the exchange's private key protection. The stolen Bitcoin was valued at approximately ¥48.2 billion (about $320 million), marking the hack as the largest crypto heist in Japan for 2024. In efforts to manage the fallout, DMM Bitcoin restricted several services, including crypto asset withdrawals. Despite financial backing from its parent company that helped to secure some funds, the long-term financial strain forced the company to cease operations.
Regulatory Scrutiny and Systemic Failures
Following the incident, Japan's Financial Services Agency (FSA) issued a business improvement order to DMM Bitcoin in September. The FSA criticized the company for its management practices, particularly the concentration of authority within a single team that handled both system operations and security. The agency pointed out a lack of decentralized management, especially concerning the private keys critical to securing customer funds. The breach on May 30 was described as an 'unauthorized leak' of private key information. DMM Bitcoin pledged to recover the stolen Bitcoin using its resources and backing from its parent company. This breach is now the second-largest hack ever suffered by a Japanese cryptocurrency exchange, following the infamous Coincheck hack of 2018. Blockchain analysts have reported that part of the stolen funds, approximately $35 million, was laundered through the crypto scam platform Huione Guarantee.
Moving Customer Assets to SBI VC Trade
As part of the restructuring, DMM Bitcoin has entered into an agreement with SBI VC Trade to transfer all customer assets to the exchange. This process is expected to be completed by March 2025. SBI VC Trade is part of the SBI Holdings group, a significant player in Japan’s financial sector, and reportedly has the infrastructure in place to handle the transfer of both fiat and crypto assets. Under this agreement, users of DMM Bitcoin will see their deposits, including both crypto and yen, moved to SBI VC Trade's platform.
