$46M Drained From Mercado Bitcoin: Are Customer Funds Really Safe?

2026-11-03

Blockchain analysts estimate that more than $46 million left Mercado Bitcoin's wallets in a security breach. The Brazilian exchange, one of the largest in the country, confirmed the incident on Monday. Analysts say the exchange's wallets showed transfers after the hack.

Mercado Bitcoin stopped all deposits and withdrawals after the breach. The exchange says its customers' funds and data were not affected. Customers cannot move money in or out while the pause lasts.

Several things are still unknown. The exchange has not said how the attackers got in or when deposits and withdrawals will start again. The $46 million figure comes from analysts' estimates; the exchange has not confirmed it. Nobody outside the exchange has yet checked its claim that customer funds are safe.

For anyone holding a perpetual position on Bitget, Bybit, MEXC or OKX, this changes nothing directly. Mercado Bitcoin is not one of the four exchanges we track, and the report says nothing about perpetual futures, funding rates, fees or liquidity on any of them. The direct effect falls on Mercado Bitcoin's own customers, who cannot move funds until the exchange reopens deposits and withdrawals.
