Do Kwon #

Introduction #

Kwon Do-hyung (born September 6, 1991), widely known as Do Kwon, is a South Korean former businessman who co-founded and served as CEO of Terraform Labs, the parent company of the crashed TerraUSD stablecoin and Luna cryptocurrency. TerraUSD and Luna collapsed in May 2022, wiping out almost $45 billion in market capitalization in one week. He was arrested in Montenegro on March 23, 2023, on falsified travel documents, extradited to the United States, and in December 2025 sentenced to 15 years in prison for fraud.

Background Information #

Kwon was born in Seoul on September 6, 1991, attended Daewon Foreign Language High School, and received a bachelor’s degree in computer science from Stanford University in 2015. He worked briefly as a software engineer for Microsoft and Apple before returning to South Korea to launch a startup that later drew scrutiny over government funding obtained through a co-founder’s parents.

In January 2018, Kwon co-founded Terraform Labs with entrepreneur Daniel Shin. The company released its Luna cryptocurrency that year and began selling TerraUSD (UST) in 2020, with the stablecoin’s value meant to stay near $1 through an algorithmic link to Luna’s supply.

The Controversy or Incident That Led to Their Cancellation #

In May 2022, TerraUSD started to break its peg to the dollar. Over the next week its price plunged to 10 cents as Luna fell from an all-time high of $119.51 to virtually zero, wiping out almost $45 billion of market capitalization. Roughly 200,000 South Korean investors were harmed; class actions followed in South Korea, the United States and Singapore, and Seoul pursued criminal charges against Kwon.

The regulatory response escalated quickly. The SEC began an investigation in June 2022 and charged Kwon and Terraform Labs with fraud in February 2023. On April 5, 2024, a jury in the Southern District of New York found Kwon and Terraform liable for defrauding investors; the SEC had argued that Kwon secretly sought third-party financing after TerraUSD slipped from its peg and then falsely claimed the recovery was due to algorithmic stability.

By then Kwon was a fugitive. A South Korean court issued an arrest warrant in September 2022, prosecutors sought an Interpol red notice, and by December 2022 Seoul said it believed he was hiding in Serbia. On March 23, 2023, he was arrested at Podgorica Airport in Montenegro attempting to fly to Dubai on falsified Costa Rican documents, and was also found carrying falsified Belgian documents. A federal grand jury in Manhattan then charged him with eight counts, including securities fraud, commodities fraud, wire fraud and conspiracy. In June 2023, a Montenegrin court sentenced Kwon and Terraform’s former finance officer to four months in prison for the forged passports; he appealed but lost in Montenegro’s highest court.

Public Reaction and Consequences #

The Terra collapse was one of the defining disasters of the 2022 crypto downturn, destroying billions in investor savings. Kwon’s flight became an international manhunt: Montenegro, which had no extradition treaty with Seoul or Washington, spent more than a year weighing competing requests. In December 2024, Justice Minister Bojan Bozovic ordered Kwon’s deportation to the United States, and he was extradited on December 31, 2024. Terraform Labs filed for Chapter 11 bankruptcy protection in the United States in January 2024.

In August 2025, Kwon pleaded guilty in Manhattan federal court to two fraud charges: one count of conspiring to commit commodities fraud, securities fraud and wire fraud, and a second count of wire fraud. He agreed to forfeit over $19 million in ill-gotten proceeds and give up his interest in Terraform; prosecutors agreed not to seek more than 12 years, even though federal sentencing guidelines recommended about 25 years. U.S. Attorney Jay Clayton said Kwon “used the technological promise and investment euphoria around cryptocurrency to commit one of the largest frauds in history.”

Current Status #

On December 11, 2025, U.S. District Judge Paul A. Engelmayer sentenced Kwon to 15 years in federal prison, exceeding the 12-year term prosecutors had agreed to seek. “This was a fraud on an epic, generational scale. In the history of federal prosecutions, there are few frauds that have caused as much harm as you have, Mr. Kwon,” Engelmayer said during the hearing in Manhattan federal court. In yellow prison garb, Kwon apologized to victims, including hundreds who wrote letters to the court: “All of their stories were harrowing and reminded me again of the great losses that I’ve caused. I want to tell these victims that I am sorry.”

Prosecutors said that when the coin slipped below its $1 peg in May 2021, Kwon told investors a computer algorithm known as the Terra Protocol had restored its value — when he had actually arranged for a high-frequency trading firm to secretly buy millions of dollars of the token to prop up its price. At his plea, Kwon admitted: “I made false and misleading statements about why it regained its peg by failing to disclose a trading firm’s role in restoring that peg. What I did was wrong.” He had already agreed in 2024 to pay an $80 million civil fine and accept a crypto ban as part of a $4.55 billion SEC settlement.

Kwon also faces charges in South Korea; prosecutors will not oppose his transfer abroad after half of his sentence, and he may return there to face a possible second trial.

Impact on Their Career/Life #

Kwon’s fall was among the most spectacular in crypto history: he went from a Forbes 30 Under 30 honoree and the celebrated founder of one of the industry’s most hyped projects to a convicted felon serving 15 years for what the judge called a fraud on an epic, generational scale. The collapse destroyed everyday savings worldwide: victim Ayyildiz Attila, who wrote to the court, said he lost between $400,000 and $500,000. “My savings, my future, and the results of years of sacrifice disappeared,” he said.

The personal fallout predated the legal reckoning. Kwon named his daughter, born in April 2022, Luna — “my dearest creation named after my greatest invention” — weeks before that invention unraveled, and days after the crash an investor who said he lost roughly $2 million trespassed into Kwon’s condo building demanding an apology. South Korean prosecutors later said Kwon had withdrawn approximately $35 million worth of cash even after his arrest in Montenegro. With a 15-year federal sentence, charges still pending in South Korea, and Terraform Labs in bankruptcy, the career that once made Kwon the face of algorithmic stablecoins is over.
