On the night of June 14, 2023, Delio users logged into the platform to withdraw Bitcoin or Ethereum, only to find their accounts locked. No warning, no announcement — the money simply couldn't be pulled out. From that night on, the name of this South Korean centralized crypto lending platform (CeFi) became inseparable from the word "fraud."
The Seoul Southern District Court this week sentenced Delio CEO Jeong (identified only by surname) to 15 years in prison. The court found that while running Delio, he obtained a virtual asset trading license through fraudulent means and embezzled roughly 70 billion won (about $50 million) in crypto assets from more than 1,100 investors. The method wasn't complicated: take in Bitcoin and Ethereum deposits, promise high returns, then shut the withdrawal gates entirely on that night in June.
Delio ultimately declared bankruptcy in November 2024.
What makes this case interesting isn't the crime itself, but the gap that emerged during the trial. Prosecutors originally sought a 20-year sentence and alleged as many as 2,800 victims. But the court excluded certain evidence that the defense had challenged on procedural grounds, ultimately narrowing the confirmed victim count to just over 1,100 and reducing the sentence to 15 years. Defense lawyers are expected to appeal. In other words, the same case saw its court-recognized "scale of fraud" cut by more than half depending on whether the evidence could hold up — yet even so, 15 years remains a severe sentence.
Placing Delio within South Korea's recent string of crypto fraud cases reveals a familiar pattern. TerraUSD (UST) and Luna, built by Terraform Labs co-founder Do Kwon, collapsed in May 2022, wiping out roughly $40 billion in investor funds in what's considered one of the largest fraud cases in financial history. That same year, seven executives at crypto exchange V Global were also convicted in a $1.7 billion fraud case, with former CEO Lee Byung-gul sentenced to 22 years. The Delio case isn't the largest in scale, but the playbook — promise high returns, then lock down withdrawals overnight — follows directly in the footsteps of these earlier cases.
