BtcTurk Pro, a prominent Turkish cryptocurrency exchange, is investigating a potential security breach after suspicious outflows totaling approximately $48 million were detected on August 14th 2025. As a major digital asset platform in Turkey with millions of users, the exchange has taken immediate action by temporarily suspending all cryptocurrency deposit and withdrawal operations. The incident has sent ripples through the cryptocurrency community, with security firms and users closely monitoring the developing situation.
The alarm was first raised by the blockchain security firm Cyvers Alerts, which identified significant and unusual movements of funds from wallets associated with BtcTurk. In response, the exchange acknowledged the “unusual technical issue” and assured users that its teams are conducting a thorough investigation. BtcTurk has emphasized that the majority of its assets are held securely in offline cold storage and that its robust financial structure far exceeds the affected amount, ensuring that user assets will not be impacted by this event.
The attackers were observed moving a diverse range of crypto assets across multiple blockchains in an apparent effort to launder the funds. While a full official list has not been released by the exchange, analysis of blockchain activity indicates the movement of several cryptocurrencies, including but not limited to Ethereum (ETH), Avalanche (AVAX), Arbitrum (ARB), Base (BASE), Optimism (OP), Mantle (MNT), Polygon (MATIC).
