South Korea’s financial regulator says it has investigated more than 40 cases of suspected unfair crypto trading since the Virtual Asset User Protection Act took effect, and it is now leaning harder on AI-based surveillance to catch the next wave of market abuse.
- 40+ cases investigated under the new crypto law
- 30+ cases referred to investigators
- 25 suspects identified by regulators
- AI surveillance is getting expanded
The Financial Services Commission (FSC) said the cases were uncovered in the first two years after the New Regulations for Virtual Asset Protection and Management took effect on July 19, 2024. FSC Chair Lee Eog-won laid out the figures as the law marked its second anniversary, and the message was pretty clear: South Korea is done treating crypto misconduct like a small-time headache.
According to the FSC, authorities have referred more than 30 of those cases to investigative agencies and identified 25 suspects tied to the alleged wrongdoing. The regulator also said the average alleged unlawful gain was about 1.4 billion Korean won, or roughly $940, 000, per case. That is not pocket change. That is the kind of number that turns “one bad trade” into “please have a seat.”
The law gives regulators a much firmer hand than they had before. It requires virtual asset service providers to keep customer holdings separate from company assets and to hold user deposits with banks. It also gives authorities power to inspect providers and act against insider trading, wash trading, and market manipulation.
Wash trading means buying and selling the same asset to create fake volume or false activity. Market manipulation is broader: any trading behavior meant to distort price or demand rather than reflect real market interest. In crypto, where thin liquidity can make some tokens easy to shove around, these tactics are not just possible, they are a recurring problem.
The FSC’s enforcement push is not happening in a vacuum. Earlier in the month, the regulator referred two suspected market manipulation cases to prosecutors, including a probe covered in Market Manipulation Tactics in Virtual Asset Trading Under. In one of them, a trader was accused of buying close to half of a token’s circulating supply before selling into rising demand. That is a pretty blunt reminder of how ugly things can get in low-liquidity markets when someone decides to play puppet master.
Lee said the agency will keep improving its market surveillance, investigation and monitoring systems using artificial intelligence.
“Today marks the second anniversary of the enactment of the Virtual Asset User Protection Act, ” Lee Eog-won said.
“We will continue to enhance market surveillance, investigation and monitoring systems based on AI, ” he added.
That AI angle matters because crypto manipulation often moves faster than a human compliance team can track. Regulators are increasingly using automated systems to flag abnormal trading patterns, suspicious bursts of activity, and price moves that do not fit normal market behavior. The goal is not magic. It is faster detection, better triage, and fewer places for bad actors to hide.
The FSC’s own framework shows how serious the regime has become. Under the Act on the Protection of Virtual Asset Users, virtual asset service providers must keep at least 80% of customer virtual assets in cold wallets, monitor abnormal transactions, and report suspicious activity. They also need liability insurance or reserves to cover customer losses in certain cases. This is not the old “trust us, bro” model. It is much closer to adult supervision, which the industry has needed for a while.
Cold wallets are storage systems kept offline, making them harder to hack than hot wallets connected to the internet. Keeping customer assets offline is not glamorous, but it is basic risk management. Sometimes the most important crypto innovation is just not losing people’s money.
South Korea is also preparing for a broader digital asset framework. The government is reviewing a Basic Act on Digital Assets that could bring crypto markets under rules more comparable to the capital markets, including tools such as account freezes and reward systems for reporting unfair trading. In plain English: the state is trying to put digital assets inside a proper rulebook instead of treating them like a side quest.
That approach has a clear upside. Stronger custody rules, better monitoring, and faster enforcement can make markets safer for ordinary users and harder for manipulators to game. It also gives legitimate exchanges and service providers a cleaner operating environment, which matters if crypto is going to function as more than a casino with a blockchain sticker on the door.
There is also a real counterpoint. Heavy regulation can absolutely smother experimentation if officials start treating every new token, wallet, or trading model like a criminal conspiracy. Crypto is still a young industry with real technical and commercial potential, and not every aggressive trade is fraud. But South Korea’s current focus is not on crushing Bitcoin or stifling honest builders. It is on cleaning up market abuse and forcing firms to handle customer funds properly.
The country is a useful test case because it has long been one of the more active crypto markets, with strong retail participation and close regulatory scrutiny. If AI surveillance and tougher custody rules reduce manipulation there, other jurisdictions will be watching. If they fail, the usual cynics will get another chance to say what many already know: rules on paper are easy. Enforcement is the hard part.
South Korea is not backing away from crypto. It is trying to impose adult supervision.
Key questions and takeaways
-
What did South Korean regulators find?
The FSC said it investigated more than 40 cases of suspected unfair crypto trading over the first two years of the South Korea flags 40 cases of crypto market manipulation. -
How many cases were referred for investigation?
More than 30 cases were referred to investigative agencies, and regulators identified 25 suspects. -
