The crypto fraudster responsible for the infamous stablecoin has been handed his sentence. Do Kwon, the former crypto entrepreneur who was behind two digital currencies that collapsed and lost an estimated $40 billion (£29.9 billion) has been sentenced by a New York judge to 15 years in prison for an “epic” fraud.
Do Kwon, a South Korean entrepreneur, co-founded Terraform Labs in Singapore in 2018 with Daniel Shin. He had studied computer science and briefly worked in tech and fintech before entering the cryptocurrency space. Terraform Labs developed the Terra blockchain, which hosted TerraUSD (UST), an algorithmic stablecoin, and its sister token Luna. TerraUSD was designed to maintain a $1 peg through an algorithmic mechanism: when UST lost value, Luna could be minted or burned to stabilize the price.
U.S. District Judge Paul A Engelmayer, who handed down the sentence, said the Stanford graduate had repeatedly lied to investors who trusted him with their money.

“This was a fraud on an epic, generational scale,” he said during Thursday’s court hearing in Manhattan.
“In the history of federal prosecutions, there are few frauds that have caused as much harm as you have.”
The system initially attracted investors through platforms such as Anchor Protocol, which offered high-yield savings programs. The algorithm relied on continuous investor confidence and inflows of capital; it lacked external collateral.
In May 2022, UST lost its dollar peg, and Luna’s price collapsed. The crash wiped out roughly $40 billion in market capitalization. Regulators and prosecutors later alleged that Kwon and Terraform Labs misled investors about the stability and risk of TerraUSD, including overstating the algorithm’s reliability.
Kwon was extradited from Montenegro in 2025 and pled guilty to conspiracy to defraud and wire fraud.
Kwon — who pleaded guilty in August to conspiracy to defraud and wire fraud — expressed remorse to the judge.
“I have spent almost every waking moment of the last few years thinking of what I could have done different and what I can do now to make things right,” he said.

It is uncertain how much of the lost investor funds will ultimately be recovered, and the broader regulatory impact on cryptocurrencies and algorithmic stablecoins is still evolving. Some analysts suggest the case may influence stricter oversight, but the extent and timing of such changes remain unclear.
The TerraUSD and Luna collapse highlights risks in algorithmic cryptocurrencies and the importance of investor protection. While Kwon’s conviction provides accountability, the full consequences for the crypto industry are still developing.
Algorithmic stablecoins, by design, can be highly sensitive to market sentiment and liquidity conditions, making them vulnerable to sudden collapses. The incident has prompted discussion among regulators, industry participants, and policymakers about the need for clearer rules and accountability in the cryptocurrency space.
The case underscores the need for robust investor protections, clearer oversight, and greater public awareness of digital asset risks.
The TerraUSD and Luna collapse offers lessons for both regulators and investors about the balance between innovation and accountability in the rapidly evolving crypto ecosystem.
