DMM Bitcoin, a Japanese cryptocurrency exchange, lost 48 billion yen ($305 million) worth of bitcoin (4,502.9 BTC) in a hack. The stolen bitcoin was distributed across 10 wallets in batches of 500 BTC. The exchange has taken measures to prevent further unauthorized outflows and assured users that the lost BTC will be covered by group companies, guaranteeing the full amount. DMM Bitcoin has restricted spot buys and warned that yen withdrawals may be delayed. This incident is the second-largest cryptocurrency theft in Japan, following the 58 billion yen Coincheck hack in 2018. Over $473 million has been lost to crypto hacks in 2024.
