70% of Korean cryptocurrency exchanges have failed to repay their customers after closing down operations. The Financial Intelligence Unit (FIU) of South Korea's Financial Services Commission (FSC) revealed this alarming statistic, emphasizing the lack of proper procedures and resources during the closure process. Many crypto investors have been left in limbo, unable to retrieve their funds due to the exchange's inability to handle the situation effectively. This issue underscores the need for stricter regulations and guidelines to protect investors' interests in the event of an exchange closure, ensuring a smooth and transparent process for returning customer assets.
