BitMEX transferred 367.65 BTC, worth about $23.92 million, from a cold wallet (offline storage for digital assets) to a hot wallet 4 hours ago, according to Onchain Lens. The on-chain monitor said the exchange has made similar transfers over the past week, a pattern that may be tied to handling retail customer withdrawals. The activity comes after BitMEX announced its closure last month. The exchange's cold wallet address was identified as bc1q...srq64.
