South Korea's Financial Supervisory Service (FSS) has highlighted the structural risks in the crypto asset system following Bithumb's recent error, where over $40 billion worth of Bitcoin was mistakenly distributed to users. The FSS noted significant vulnerabilities in virtual asset electronic systems and emphasized the need for stricter regulations. In response, the agency plans to enhance relevant legislation and carefully assess the progress of Bitcoin spot ETF policies. An investigation revealed that approximately 620,000 BTC were mistakenly issued, of which 99.7% have been recovered. Additionally, about 93% of the sold portion has also been retrieved, according to the FSS.
