Overview
- An employee entered BTC instead of Korean won during a “Random Box” reward, crediting roughly 620,000 BTC across 695 accounts.
- Internal controls flagged the anomaly within about 20 minutes, with trading and withdrawals on affected accounts fully blocked by 7:40 p.m. local time.
- Bithumb says 618,212 BTC was recovered and 93% of the roughly 1,788 BTC sold was reclaimed, leaving about 125 BTC outstanding to be covered by corporate funds.
- The exchange will reimburse users who sold at unfavorable prices at 110% of their loss, grant 20,000 KRW to active users during the incident, and waive fees for a week.
- The company says no hack occurred and customer assets remain secure, while authorities from the FSC, FSS, and FIU conduct on-site reviews of controls and custody practices.
