Mercado Bitcoin Vows to Cover Customer Losses After Massive Hack

Mercado Bitcoin disclosed on Nov. 2, 2026, that a security breach resulted in the loss of roughly $38 million in digital assets, making it one of the largest incidents to hit a Latin American crypto platform. The Brazilian exchange pledged to cover customer losses from its own balance sheet, shielding users from the immediate impact of the hack. The incident poses a financial and operational challenge for one of the region's biggest exchanges and has drawn scrutiny from customers and blockchain investigators. Details on which assets and wallets were affected, and how the attackers gained access, remain key questions for the market. What to watch next: whether Mercado Bitcoin confirms the full scope of the loss, how quickly reimbursements are processed, and whether the breach prompts tighter custody and security standards across Latin American exchanges.
