South Korea’s Crypto Crackdown Lands Delio CEO 15 Years

Court Finds Customer Assets Were Misused

According to regional reports, the Seoul Southern District Court issued the ruling Aug. 13 and ordered Jeong detained immediately, citing a risk that he could flee. Prosecutors had sought a 20-year prison term.

The court found Jeong guilty of embezzling about 70 billion won, or $49.2 million, in customer assets. It also convicted him of submitting false documents when registering Delio as a virtual asset service provider, a government-recognized category for crypto businesses.

An accounting firm report submitted for the registration overstated Delio’s coin holdings by about 47.6 billion won, or $34 million, according to the court. Judges said Jeong obtained the company’s license dishonestly and promoted services Delio lacked the capacity to provide.

Withdrawal Freeze Left Users Without Access

Delio operated as a cryptocurrency deposit and lending company, marketing itself as a digital asset bank. Customers deposited bitcoin, ethereum and other crypto assets in exchange for interest payments.

The company’s problems became public in June 2023, when it abruptly froze customer withdrawals. Thousands of users could no longer access assets they had entrusted to the platform.

The suspension came during a broader crisis for crypto lending firms. Delio had placed customer assets with outside counterparties that suffered losses linked to the 2022 collapse of crypto exchange FTX. Haru Invest, another South Korean yield platform, also halted deposits and withdrawals around that time.

Illegal Search Ruling Weakened Larger Case

A Newsis report notes that Jeong was acquitted on a larger allegation involving about 250 billion won, or $175.6 million, from roughly 2,800 customers. The judges ruled that key data from a server operator had been obtained illegally.

Investigators did not protect Delio’s right to participate in the search or provide a list of seized items, the court said. That meant the database and evidence derived from it could not be used, weakening the main prosecution case.

Still, prosecutors had separate fallback charges involving about 1,100 victims and 70 billion won. Those charges formed the basis for the conviction. Jeong was also acquitted on allegations involving 41 additional victims because supporting evidence was not submitted.

Tougher Crypto Oversight Faces a New Test

The ruling matters beyond Delio because South Korea has tightened crypto oversight following failures, including Terra-Luna and FTX. The Virtual Asset User Protection Act, which took effect in 2024, strengthened rules on custody, transparency and customer protections.

Delio was declared insolvent in November 2024, beginning liquidation proceedings to sell assets and distribute funds to creditors. Recovery for depositors remains uncertain, as it often does after crypto lending platforms fail.

Jeong may appeal the ruling. Depositors, investors and regulators will watch the liquidation process, any appeal and whether the case prompts closer scrutiny of crypto firms that hold customer assets.
