South Korea has sentenced Delio CEO Jeong Sang ho to 15 years in prison after the Seoul Southern District Court found him guilty of defrauding customers of about 70 billion Korean won, roughly $49 million, in cryptocurrency. The ruling marks a major development in the case surrounding the collapse of Delio, a crypto deposit platform that halted withdrawals in 2023 and was declared bankrupt in 2024.
The sentence is five years shorter than the 20 year term prosecutors requested. The court also acquitted Jeong of the larger fraud allegation involving approximately 250 billion won and about 2,800 customers after ruling that key evidence obtained during a server seizure was illegally collected.

Court Finds Delio CEO Guilty Over $49 Million in Crypto
The Seoul Southern District Court found Jeong guilty on several charges linked to Delio’s handling of customer assets. Prosecutors had accused the executive of misleading customers while the company’s financial position deteriorated and sought a 20 year prison sentence. The court ultimately imposed 15 years, describing the conduct covered by the conviction as extremely serious because of the number of victims and scale of the financial losses.
The ruling also included convictions related to embezzlement and the use of falsified documents when Delio registered as a virtual asset service provider. Prosecutors alleged that a false accounting report overstated Delio’s cryptocurrency holdings by approximately 47.6 billion won. The court ordered Jeong to remain detained, citing concerns that he could flee.
Why the Larger Fraud Charge Was Dismissed
One of the most significant aspects of the ruling was the court’s decision to acquit Jeong on the larger allegation involving approximately 250 billion won and 2,800 customers. The dispute centered on evidence obtained during a search and seizure involving Gabia, the company hosting Delio’s servers. Jeong’s legal team argued that investigators had failed to protect his procedural rights during the search and had not properly provided an inventory of the materials seized.
The court agreed that the evidence had been unlawfully obtained and therefore could not be used to support the primary fraud charge. This significantly narrowed the case against Jeong. Prosecutors had originally alleged that he took approximately 250 billion won in cryptocurrency from customers between August 2021 and June 2023. Earlier in the year, prosecutors had requested the 20 year sentence based on those allegations. The ruling therefore demonstrates how the handling of digital evidence can become decisive in major cryptocurrency criminal cases.
Delio’s Collapse Began With a Withdrawal Freeze
Delio operated a cryptocurrency deposit and lending business that promised customers returns on assets including Bitcoin and other cryptocurrencies. The company promoted itself as a digital asset banking platform and offered yields of up to around 10% on some products. The business came under severe pressure in June 2023. Delio abruptly suspended withdrawals on June 14 after problems involving Haru Invest, another South Korean crypto yield platform with which Delio had a business relationship.
Customers were subsequently unable to access their deposited assets, triggering complaints and legal action. Delio later sought rehabilitation, but the Seoul Rehabilitation Court rejected the application after determining that liquidation was more appropriate given the company’s financial position. The court eventually declared Delio bankrupt in November 2024.
What the Sentence Means for Crypto Platforms
The 15 year sentence sends a strong warning to operators of centralized crypto platforms that hold customer assets. Unlike decentralized protocols, deposit and lending businesses take direct control of users’ cryptocurrency. That creates additional risks involving custody, asset management, liquidity and counterparty exposure. Delio’s collapse illustrates how quickly customers can lose access to their assets when a centralized platform encounters financial problems.
For South Korean crypto businesses, the ruling also reinforces the potential criminal consequences of misleading customers, misusing assets or providing inaccurate information during regulatory registration.
For investors, the case highlights the need to look beyond advertised yields when evaluating centralized crypto platforms. Asset segregation, proof of reserves, withdrawal conditions and the financial health of the company holding the assets can be just as important as the return being offered.
Conclusion
Jeong Sang ho’s 15 year prison sentence closes a major chapter in the criminal case surrounding Delio, but it does not resolve the broader question of how affected customers will recover their assets. The court’s decision to uphold convictions over approximately 70 billion won while rejecting the larger 250 billion won allegation also shows how procedural safeguards and digital evidence can significantly shape cryptocurrency fraud prosecutions.
For South Korea’s crypto industry, the Delio case is likely to remain a reference point for how courts treat executives responsible for customer assets, particularly when platforms combine high yield products with centralized custody.
