South Korea’s Financial Intelligence Unit, operating under the Financial Services Commission, asked the country’s communications review authority on Oct. 30 to block domestic access to TetherMax and SuperTrust, including their online services. The request followed referrals by the Digital Asset Exchange Alliance against TetherMax, SuperTrust and Aegis Ventures for allegedly operating virtual-asset businesses without registration under the Specific Financial Information Act, also known as the Act on Reporting and Using Specified Financial Transaction Information. The latest referrals bring the number of unregistered cryptocurrency businesses reported to investigative authorities to 47. Aegis Ventures was excluded from the blocking request because it has no standalone website or mobile application. The existing record referred to the same entity as Eizis Ventures, while the latest report identifies it as Aegis Ventures. Upbit separately announced restrictions on deposits and withdrawals involving the three operators. Unregistered virtual-asset operations, including by overseas firms serving South Korean residents, can carry up to five years in prison or a 50 million-won fine. A joint June inspection found trading fees of 1.5% to 10% at identified operators, compared with an average of about 0.16% at South Korea’s five largest won-based exchanges. The FIU warned that platforms outside regulatory oversight could create money-laundering, fraud, hacking and personal-data risks.
