South Korean crypto exchange races to recover $40bn of bitcoin sent to customers by mistake

Bithumb, South Korea’s second-largest cryptocurrency exchange, initiated an emergency recovery operation in Seoul this week after a staff member accidentally distributed 620,000 bitcoins—valued at over $40 billion—to customers' accounts during a promotional event held last week. This massive financial blunder occurred when the employee mistakenly credited users with the digital currency instead of the intended 620,000 South Korean won, a sum equivalent to only a few hundred U.S. dollars. The exchange issued a formal apology for the administrative oversight, which briefly placed a significant portion of the global bitcoin supply in the hands of a small group of retail investors. The error took place during what was meant to be a routine marketing campaign aimed at increasing user engagement via modest cash rewards. However, the confusion between the domestic currency unit and the world's largest cryptocurrency created a massive discrepancy in the firm's ledgers. Upon realizing the magnitude of the error, Bithumb executives immediately froze withdrawal capabilities for affected accounts to prevent the permanent loss of the digital assets, which represent a staggering market value far exceeding the company's total capitalization. While Bithumb has reported that it successfully reversed the majority of the mistaken credits, the exchange confirmed that approximately 13 billion Korean won, or roughly $9 million, remains outstanding and has yet to be recovered. The company is currently working with legal experts and reaching out to individual users to secure the return of the remaining funds. This incident highlights ongoing concerns regarding the operational security and internal controls within the high-stakes cryptocurrency industry, particularly in South Korea's highly active trading market. Regulators in South Korea have been closely monitoring the situation to ensure that the exchange complies with financial safety protocols. Bithumb has assured its user base that its own holdings and the assets of uninvolved customers remain secure and unaffected by the glitch. Nevertheless, the scale of the potential loss serves as a stark reminder of the volatility and technical risks associated with managing digital asset platforms where a single clerical error can trigger multi-billion dollar consequences.
