[South Korean Exchange Coinone Sues Financial Intelligence Unit, Seeks to Halt Regulatory Penalty] Odaily Planet Daily reports that South Korean cryptocurrency exchange Coinone has filed a lawsuit against the South Korean Financial Intelligence Unit (FIU) over its penalty measures. Coinone has also submitted an application to the Seoul Administrative Court to suspend the enforcement of these measures, aiming to pause the sanctions before they take effect on April 29. The core of the sanctions involves restricting new users from depositing and withdrawing crypto assets to and from external exchanges. Previously, the FIU imposed a three-month partial business suspension and a fine of 5.2 billion KRW on Coinone for violating the Specific Financial Information Act. (Naver)
