ThunderCore’s TT token surged 211% from the previous day around 6 p.m. on Aug. 31 before falling more than 70% within a day as Upbit ended trading support at 9 a.m. on Sept. 1. The move followed an earlier reported price of 0.577 won, up 253.99%, and a later account placing TT at about 0.538 won. Trading-support terminations can restrict deposits and withdrawals across exchanges, reducing liquidity and making prices more vulnerable to manipulation through wash trading and bots. The Financial Supervisory Service said it operates an AI-based market-surveillance system, but pump-and-dump schemes involving virtual assets are not clearly covered by current law because such assets are not classified as financial investment products under the Capital Markets Act. Penalties may apply when intent is proven, although establishing deliberate manipulation remains difficult.
