Turkish cryptocurrency platform BtcTurk is investigating a suspected security breach after about $48 million to $50 million in digital assets were moved out of wallets linked to the exchange. Blockchain-analytics firms CertiK and Cyvers flagged the transfers, noting that funds spanning seven networks—including Ethereum, Avalanche and Polygon—were consolidated into two addresses before being rapidly swapped for ether. BtcTurk has suspended deposits and withdrawals while it works with external security teams to determine the source of the outflows and recover the assets. The exchange has not yet confirmed whether customer balances were affected or provided a timeline for restoring full service.
