Delio CEO Jeong Sang-ho receives 15-year sentence for crypto fraud

Delio CEO Jeong Sang‑ho was sentenced to 15 years in prison on Friday for fraud related to the crypto platform he co‑founded, a verdict handed down by Seoul’s Central District Court. The ruling follows a 2023 indictment that accused Jeong of embezzling client funds and falsifying transaction records to inflate the company’s token sales. The sentence is the longest ever imposed on a Korean crypto executive and signals a hardening stance by authorities on digital asset fraud.

Delio, launched in 2019, positioned itself as a hybrid exchange‑wallet service that offered low‑fee trading and a proprietary token, D‑Token. Within two years the platform had attracted roughly 300,000 users and managed more than 1.5 billion won in deposits. In late 2022, the Financial Services Commission (FSC) opened a probe after whistleblowers reported irregularities in the company’s accounting. Prosecutors alleged that Jeong and his co‑founders siphoned off approximately 1.2 billion won—about 900 million USD—by creating phantom accounts and issuing fake receipts, then used the proceeds to purchase luxury goods and offshore investments.

The court’s decision was based on a 12‑month trial that included testimony from former employees, forensic audits, and digital evidence of transaction logs. Jeong denied wrongdoing, claiming the funds were part of a legitimate liquidity‑pool scheme. However, the judge found the evidence compelling, noting that Jeong’s personal accounts were linked to the same wallets used by the company’s “internal” accounts. Investors reacted with sharp sell‑offs; Delio’s token price fell 45 % in the week after the indictment, wiping out nearly 200 million won of market cap. The FSC announced it would review all pending crypto‑exchange licences and consider stricter audit requirements.

Jeong is expected to file an appeal within the next month, but the Seoul court’s ruling is likely to deter other crypto operators in South Korea. Regulators are already drafting a new framework that would require real‑time monitoring of token transactions and impose harsher penalties for misappropriation. Industry observers say the case underscores the need for clearer compliance standards and stronger investor protections as South Korea continues to position itself as a leading hub for digital asset innovation.
