US prosecutors have asked a judge to give Do Kwon, Terraform Labs co-founder, a 12-year prison sentence for his role in the remarkable $40 billion collapse of the Terra and Luna tokens. The request also seeks to finalize taking away Kwon’s criminal earnings.

The court filing came in New York’s Southern District on Thursday. This is about four months after Kwon admitted guilt on two charges: wire fraud and conspiracy to defraud. Prosecutors said Kwon caused more losses than Samuel Bankman-Fried, Alexander Mashinsky, and Karl Sebastian Greenwood combined.

U.S. prosecutors have asked a New York federal judge to sentence Terraform Labs co-founder Do Kwon to 12 years in prison, calling his role in the 2022 TerraUSD collapse a “colossal” fraud that triggered broader crypto-market failures, including the downfall of FTX. Sentencing is…

Terraform Collapse Shakes Crypto Market

Authorities explained that Terraform’s collapse affected the entire crypto market. They said it helped trigger what is now called the ‘Crypto Winter.’ The filing stressed that Kwon’s conduct harmed many investors and the broader crypto world. On Thursday, prosecutors said Kwon must give up just over $19 million. They added that they will not ask for any additional restitution.

They said:

“The cost and time associated with calculating each investor-victim’s loss, determining whether the victim has already been compensated through the pending bankruptcy, and then paying out a percentage of the victim’s losses, will delay payment and diminish the amount of money ultimately paid to victims.”

Authorities will sentence Do Kwon on December 11. They charged him in March 2023 with multiple crimes, including securities fraud, market manipulation, money laundering, and wire fraud. All connections are tied to his role at Terraform. After Terra fell in 2022, authorities lost track of Kwon until they arrested him in Montenegro on unrelated charges and sent him to the U.S.

Do Kwon’s Legal Case and Sentencing

In April last year, a jury ruled that both Terraform and Kwon committed civil fraud. They found the company and its co-founder misled investors about how the business operated and its finances. Jay Clayton, U.S. Attorney for the Southern District of New York, submitted the sentencing request in November.

TERRA STATEMENT: “We are very disappointed with the verdict, which we do not believe is supported by the evidence. We continue to maintain that the SEC does not have the legal authority to bring this case at all, and we are carefully weighing our options and next steps.”

The news of Kwon’s sentencing caused Terraform’s token, LUNA, to jump over 40% in one day, from $0.07 to $0.10. Still, this rise remains small compared to its all-time high of more than $19, which the ecosystem reached before collapsing in May 2022.

In a November court filing, Do Kwon’s lawyers asked for a maximum five-year sentence. They argued for a shorter term partly because he could face up to 40 years in prison in South Korea, where prosecutors are also pursuing a case against him. The legal team added that even if Kwon serves time in the U.S., he would not be released freely. He would be moved from prison to an immigration detention center and then sent to Seoul to face pretrial detention for his South Korea charges.
