A court in Seoul has sentenced Delio chief executive Jeong Sang-ho to 15 years in prison after finding him guilty of embezzlement and of using false documents to register the company as a virtual asset service provider. The sentence was lower than the 20 years sought by prosecutors, but the court still described the conduct it upheld as extremely serious.

The Seoul Southern District Court at the same time acquitted Jeong on the case’s largest fraud allegation, which accused him of cheating about 2,800 people out of roughly 250 billion won, or $175.6 million. The court said key evidence from a search and seizure involving a server operator had been obtained illegally and could not be used.

What the court decided

According to the ruling, the surviving convictions centered on a scheme that prosecutors said caused losses of around 70 billion won, about $49.2 million, in crypto assets. Judge Jang Chan of the Seoul Southern District Court handed down the 15-year prison term and ordered Jeong detained, citing flight risk.

Although the court rejected the central fraud count, it did not minimize the offenses it did uphold. In its reasoning, the court said the crime was extremely grave, pointed to the scale of the damage, and noted that Jeong had not been forgiven by victims who suffered serious economic losses.

Why the main fraud charge failed

The biggest allegation in the indictment was that Jeong defrauded about 2,800 people of around 250 billion won. That charge would have made the case substantially larger than the conduct covered by the embezzlement conviction.

The court acquitted Jeong on that count because it found that evidence obtained through the search and seizure of a server operator was collected unlawfully. With that evidence excluded, the prosecution did not keep the core charge intact.

Delio’s collapse and the broader setting

Delio had presented itself as a digital asset bank that offered high returns on crypto deposits. The company suspended withdrawals in June 2023 and was later declared bankrupt in November 2024.

The case is unfolding as South Korea strengthens its crypto enforcement framework. After the 2024 Act on the Protection of Virtual Asset Users took effect, the Financial Services Commission built a dedicated virtual asset investigation division, giving regulators and prosecutors more capacity to pursue cases of this kind than existed when Delio first halted withdrawals.

A tougher regulatory era for Korea’s crypto market

South Korea is also preparing wider oversight changes beyond criminal enforcement. Blockhead reported in May that the country plans to begin taxing crypto capital gains in January 2027 after repeated delays, while an anti-money-laundering overhaul could sharply expand the number of flagged transactions, based on an industry warning cited in that report.

At the same time, ownership of the exchange sector is shifting. Mirae Asset Securities disclosed this week that it will put another $35 million into Korbit after acquiring the exchange in July, while OKX Ventures and Korea Investment & Securities each bought 19.6% stakes in Coinone in May for a combined $53 million. Those moves come as courts and regulators continue to work through cases from an earlier, less tightly regulated phase of the market.

What comes next

For now, the confirmed outcome is Jeong’s 15-year sentence, detention on flight risk grounds, and his acquittal on the largest fraud allegation because the court excluded key evidence. The ruling leaves in place serious convictions, but it also narrows the case well below the headline fraud amount originally alleged by prosecutors.

More broadly, the decision arrives at a time when South Korea is pairing stricter enforcement with a more institutional market structure. How effectively that combination reduces the chance of another collapse like Delio’s remains unresolved, but the legal and regulatory direction is becoming clearer.
