KCEX Unregistered Exchange Evades South Korean Ban: iOS App Store Loophole Exposed

KCEX, an unregistered overseas crypto exchange, continues to operate in South Korea by using an iOS App Store distribution loophole, undermining the FSC/KoFIU registration regime and exposing gaps in enforcement. The app remained accessible to South Korean users as of April 22, 2025, despite KCEX being flagged for unregistered activity in August 2024. The case raises investor-protection and market-stability concerns — unregistered platforms can offer higher leverage, weaker custody controls and greater manipulation risk — and may push regulators to press app stores for takedowns, seek stronger international cooperation, or mandate technical monitoring. Market effects could include increased regulatory scrutiny on crypto apps, potential restrictions on app distribution, and short-term flight of retail users to unregulated venues, heightening counterparty and liquidity risks for crypto markets.
