Mercado Bitcoin assures users they won't lose funds following $38 million security breach Mercado Bitcoin has assured customers they won't lose funds after a security incident led to the suspension of deposits and withdrawals, with about $38 million involved. The exchange has blocked 11 million dollars in cooperation with various partners and is continuing the recovery efforts to identify and contain additional amounts. The incident follows a broader trend of security breaches in the crypto industry, including a recent $6.3 billion hack at Binance and the suspected theft of more than $133 million from central exchanges linked to an unnamed EU entity.
