Bithumb Apologizes for Incorrect Payment Incident and Reveals Compensation Plan Bithumb has issued an apology announcement regarding the erroneous payment incident. Bithumb stated that it failed to adhere to the primary principles of virtual asset trading platforms: "stability and integrity". After the incident, it has been reported to all relevant departments and we are fully cooperating with the investigation of the State Administration of Financial Supervision and Administration. Bithumb will prevent human errors from escalating into accidents by improving its systems and processes. To prevent such incidents from happening again, Bithumb has upgraded its internal control system and developed innovative measures. (1) Strengthening the asset verification system: We will enhance the verification of customer and company assets during the payment process based on events or company policies. (2) Improving the Multi Payment System: We will improve certain processes that were previously missing, ensuring that customer asset transfers and reward payments require at least two payment steps to be completed, in order to prevent similar incidents from happening again. (3) Strengthen the AI system for detecting and automatically intercepting abnormal transactions: Once abnormal transactions or data are detected, the system will immediately activate the "security guarantee" system, running 24 hours a day without interruption, to prevent incidents from occurring at the source. (4) External expert system audit: We will commission a global security expert organization to conduct a comprehensive system evaluation of Bithumb and publicly disclose the results in a transparent manner. 2. The company will bear full responsibility for preventing customer losses. Since the second announcement, there have been no direct customer asset losses caused by overpayment events. However, due to the sharp drop in prices, it was confirmed during the event that there were some transactions that were unfavorable to customers (panic selling). Bithumb believes that these transactions fall within its responsibility to protect its customers and plans to provide full compensation, including additional compensation, to affected customers. As of 4:00 PM on February 7, 2026, it is estimated that the customer's loss will be approximately 1 billion Korean won. The company plans to compensate for any additional losses. (1) Special compensation for panic selling: Users who sell at a low price during the event period (February 6, 2026, 19:30-19:45) will receive the full selling price plus an additional 10% compensation. (Automatic payment within one week after data verification.) (2) Compensation for all Bithumb users accessing Bithumb services during the event: All users accessing Bithumb services during the event will receive a compensation of 20000 Korean won within one week. (3) All users are exempt from transaction fees: the transaction fees for all trading varieties will be reduced to 0% for a period of seven days. (To be notified separately) (4) Establish a 100 billion Korean won "Customer Protection Fund": A special fund will be set up to immediately rescue customer assets in the event of an incident.
