Bithumb Mistakenly Sends 620,000 Bitcoin ($40B) to Customer Accounts

On 6 February 2026 Bithumb accidentally credited roughly 620,000 BTC to 695 customer accounts during a promotional payout, briefly causing a sharp local price drop; internal controls limited trading/withdrawals and the exchange recovered approximately 99.7% of the misplaced funds while stating the issue was an internal operational error rather than a hack. Regulators have opened inquiries and the report highlights Bithumb’s history of prior breaches and insider-related thefts, increasing scrutiny of its controls and prompting promises of improved verification and monitoring.
