South Korea’s Bithumb said it retrieved 99.7% of Bitcoin mistakenly credited to users during a promotional reward error the same day. The remaining 0.3% — 1,788 BTC that had already been sold — was paid from company reserves to fully match customer balances. Bithumb said the incident was not a hack, deposits and withdrawals continued, affected accounts were restricted to stabilize trading, and compensation (cash, extra reimbursement for sellers, and seven days of fee waivers) was offered. The exchange did not disclose the total amount involved; some users estimated roughly 2,000 BTC was credited.

Facts: 99.7% of overcredited BTC was recovered same day; 0.3% (1,788 BTC) had been sold and was covered by company funds; Bithumb said it was not a hack, deposits/withdrawals continued, and trading was stabilized after restricting affected accounts. These facts show a resolved operational failure with a small realized sell-off that required corporate reimbursement, supporting a slightly negative sentiment but limited market-moving impact.
