DMM Bitcoin Hacked for $305 Million

Unauthorized Access Incident

On May 31, DMM Bitcoin, a major Japanese crypto exchange, detected a hack resulting in the theft of 4,502.9 BTC (worth $305 million).

Services Suspended

To protect customer assets, DMM Bitcoin has temporarily suspended:

  • New account openings
  • Cryptocurrency withdrawals
  • Spot trading buy orders
  • New leveraged trading positions

Customer Reassurance

DMM Bitcoin has promised to cover the losses and guarantee the full value of customer BTC holdings. Japanese law separates exchange assets from customer assets, providing additional protection.

Lessons from Coincheck

The hack echoes the 2018 Coincheck hack, leading to stricter regulations and increased focus on security in the crypto exchange industry.
