Brazil's Largest Exchange Mercado Bitcoin Halts Withdrawals After $40 Million Hack

Brazil's largest crypto exchange, Mercado Bitcoin, confirmed a security incident on November 2, suspending deposits and withdrawals after blockchain security firm Hypernative identified over $40 million in suspicious transfers linked to the platform. The exchange stated that customer funds were unaffected, but it has not confirmed the reported losses or disclosed how the attack occurred. The incident raises concerns about security at one of Latin America's largest crypto platforms, which serves millions of users in Brazil's growing digital asset market. Investors and users should watch for updates on the exchange's investigation, potential resumption of withdrawals, and whether the stolen funds move through mixers or exchanges.
