South Korean regulators investigated roughly 40 cases of unfair trading in the virtual-asset market after the Virtual Asset User Protection Act took effect in July 2024. The enforcement push shows crypto market manipulation has become a central priority for Korean financial authorities.
The Financial Services Commission said more than 30 cases were referred to investigative agencies, with 25 suspects identified across the two-year period. The results give regulators an enforcement baseline for expanding surveillance, penalties and asset-freeze powers.

Manipulation Cases Reveal Large Illicit Gains
Regulators estimated average unlawful gains of about 1.4 billion won per case, equal to roughly $940,000. Eight cases involved illicit profits between 500 million and 5 billion won, while one case exceeded 5 billion won, showing substantial profit potential behind short-term crypto manipulation schemes.
Authorities also used penalty surcharges to recover proceeds. In at least two cases, they applied surcharges equal to 125% to 165% of illicit gains, making financial recovery part of the enforcement toolkit rather than prosecution alone.
Investigators documented several tactics adapted to crypto market structure. One was the “gathuri” method, where traders inflated prices around tokens whose deposits or withdrawals were suspended, exploiting temporary exchange frictions to distort market prices.
Another pattern was the “racehorse” strategy, involving rapid coordinated buying to create short, sharp price moves. Regulators also flagged API-key exploitation, issuer-trader collusion, overseas exchange coordination and social media-driven meme-token pumps, highlighting a widening range of manipulation vectors across retail-facing markets.
Authorities also identified arbitrage-style abuse involving linkages between USDT and BTC prices across platforms. That finding matters because cross-market pricing relationships can become manipulation channels when surveillance is fragmented.
AI Surveillance and Freeze Powers Move Forward
The enforcement results are now shaping South Korea’s next regulatory phase. Authorities plan to strengthen market monitoring with artificial intelligence, giving supervisors faster tools to detect suspicious order patterns and abnormal trading behavior.
Planned measures also include account and bank-account payment suspension mechanisms designed to block concealment of illicit proceeds. If adopted, those tools would give regulators a more direct route to interrupt suspect flows before gains disappear.
A reporting-and-reward system is also under consideration to encourage disclosure of unfair trading. That would extend enforcement beyond official surveillance by adding whistleblower incentives to South Korea’s virtual-asset oversight model.
Compliance teams will need stronger trade surveillance, tighter API-access controls, clearer escalation procedures and better monitoring of thinly traded tokens, making market-abuse detection a core operating requirement.
Market makers and liquidity providers may also face more scrutiny. Coordinated activity, wash-like patterns or sudden volume bursts around restricted tokens could trigger reviews, increasing counterparty-screening and settlement-friction risks during suspicious activity events.
The enforcement push raises the importance of transaction provenance and governance documentation. Firms will need to show how they monitor suspicious flows, respond to regulatory requests and manage exposure to manipulated markets.
South Korea’s next phase will likely combine AI surveillance, stronger freezing powers and rewards for reporting misconduct. For market participants, that means algorithmic strategies, API usage and cross-exchange liquidity behavior will face much closer regulatory examination.
