Bitcoin, Brazil's largest cryptocurrency exchange, has been targeted in a cyberattack, resulting in the suspension of deposits and withdrawals. The incident was confirmed by the exchange on November 2, 2026, with the company stating that it had quickly contained the breach.
Blockchain security firm Hypernative estimates that the attack resulted in a loss of approximately $40 million from the exchange's wallets. This figure is corroborated by both BeInCrypto and The Cryptonomist. The exchange has assured users that their funds and personal data remain secure.
The incident comes just days after the record-breaking $6 billion hack of Binance, raising concerns about the security of cryptocurrency exchanges. Mercado Bitcoin's quick response and containment efforts, as reported by The Cryptonomist, may help mitigate some of the potential damage.
The broader cryptocurrency market remains relatively stable despite the news, with the total market cap at $2.67 trillion. Bitcoin, the largest cryptocurrency by market cap, is currently trading at $77,488, down 0.56% in the last 24 hours and 3.59% over the past week.
The incident highlights the ongoing security challenges faced by cryptocurrency exchanges and the potential impact on user trust and regulatory scrutiny. As the investigation continues, the market will be watching for any further developments and the exchange's response to the breach.
