News: South Korean cryptocurrency exchange Bithumb accidentally sent over $44 billion worth of Bitcoin to users as promotional rewards. The exchange intended to distribute small cash rewards of 2000 Korean won or more, but 695 customers received at least 2000 Bitcoin each. Bithumb has recovered 99.7% of the 620,000 Bitcoin and restricted trading/withdrawals for affected users within 35 minutes of the error.
AI Analysis: This incident highlights the operational risks associated with cryptocurrency exchanges and the potential for significant financial losses due to human error. While Bithumb recovered most of the funds, the initial selloff triggered by the mistake demonstrates the market's sensitivity to such events.
