Mercado Bitcoin reopens logins after $48.6M hack
6.6 Security Mercado Bitcoin is gradually restoring account access after a $48.6M hack. Users can check balances, but trading and withdrawals are still suspended. The exchange will cover losses and enhance security before full reopening.
Mercado Bitcoin, one of Brazil’s leading cryptocurrency exchanges, has started a phased restoration of account access after a security breach led to a $48.6 million loss from its wallets. As of Monday, users can log in via the website to view their balances, portfolio values, and investment breakdowns by asset and category. However, trading, deposits, withdrawals, transfers, and new account registrations remain suspended for now. The reopening process is gradual, with full login access expected for all customers by 18:00 local time. API access, Pix and TED payments, and MB card functions will be restored in later phases. The exchange confirmed that customer balance records have been preserved and pledged to use its own funds to cover any customer shortfalls. Before resuming full operations, each phase will undergo security checks. Users must revalidate their registration details and set new passwords. Withdrawals, once available, will be limited to accounts matching the user’s name and CPF tax ID. Displayed balances reflect the status as of November 2, the date of the attack.
