BitMart founder confirms small hack, links it to Mercado Bitcoin attackers
BitMart founder Sheldon Xia confirmed the winding-down exchange was hacked on 2 November but called the loss small without giving a figure. Blockchain analytics firm Bitquery estimates about $391,000 left BitMart-linked wallets on three chains, starting shortly before the Mercado Bitcoin exploit and using the same attacker addresses. Xia said the security team is badly understaffed after restructuring; BitMart stopped trading in August and plans to close in January 2027.
