Overview
- Bithumb said 620,000 BTC were mistakenly credited to 695 users on Friday, triggering a brief plunge on its KRW market to 81.1 million won, roughly 10–17% below other venues.
- The exchange reported retrieving about 618,212 BTC, or 99.7% of the total, and said remaining shortfalls will be covered with corporate assets.
- Company data and independent reporting indicate the balances existed only on Bithumb’s internal ledger, with no on‑chain bitcoin moved.
- Customers who sold at unfavorable prices will be reimbursed the full price difference plus a 10% bonus, with estimated losses around 1 billion won as of Saturday.
- South Korea’s Financial Services Commission and Financial Supervisory Service launched inspections, while Bithumb pledged system upgrades, an AI‑driven safeguard, and a 100 billion won customer protection fund.
