South Korean lawmakers questioned Bithumb CEO Lee Jae-won on Wednesday about a $4 billion Bitcoin erroneous transfer caused by human error. The incident occurred during a promotional event last week when an employee mistakenly processed customer payments in Bitcoin instead of Korean won, resulting in counterfeit Bitcoin circulating in the market. Democratic Party lawmaker Min Byeong-deok stated that Bithumb gifted Bitcoin that the company did not own, constituting naked short selling. The Financial Supervisory Service has launched an investigation into the compliance system and risk management of the country's second-largest digital asset platform. Financial Services Commission Vice Chairman Kwon Dae-young stated that the government believes this incident exposed risks associated with virtual assets and vulnerabilities in internal control systems, and will seek institutional reforms through an emergency response team, including inspections of all exchanges.
