Key Takeaways:
U.S. authorities are pushing for one of the toughest sentences yet in a crypto fraud case, arguing that Terraform Labs founder Do Kwon built his empire on calculated deception and triggered a chain reaction that rattled the entire digital asset market. His sentencing is scheduled for December 11, 2025, in Manhattan federal court.
Below is a breakdown of what prosecutors allege, why they say 12 years is justified, and what it means for crypto.

In a detailed filing to Judge Paul A. Engelmayer of the Southern District of New York, U.S. prosecutors describe Do Kwon as the architect of a “deliberate fraud” that powered Terraform Labs’ rapid rise and brutal collapse.
Between 2018 and 2022, Kwon marketed Terraform’s products including the algorithmic stablecoin TerraUSD (UST) and the LUNA token, as cutting-edge, decentralized finance tools that were transparent, resilient, and governed by code and community.
According to the government, the reality was the opposite:
At its peak in the spring of 2022, the Terraform ecosystem reached a market value of more than $50 billion. When UST depegged and the ecosystem unraveled, over $40 billion in value was wiped out, with retail and institutional investors bearing most of the losses.
Prosecutors argue these losses exceed the damage attributed to Sam Bankman-Fried’s FTX, Celsius’s Alexander Mashinsky, and OneCoin’s Karl Sebastian Greenwood combined, placing Terraform among the most devastating failures in crypto history.

A central pillar of the case is how UST was marketed versus how it actually functioned.
Kwon claimed the Terra Protocol could keep UST pegged to $1 through algorithmic incentives and market dynamics, no centralized support needed. But court documents say that when UST lost its peg in May 2021, the system did not recover on its own.

Instead, Kwon allegedly struck a secret deal with a high-frequency trading firm to buy large amounts of UST and force the price back to $1. Publicly, this rebound was showcased as proof that the algorithm and design worked as promised. Privately, it was a bailout that investors never knew about.
Prosecutors say this undisclosed intervention was not a minor detail: it went to the core risk of the product. Buyers were led to believe they were relying on a robust, autonomous mechanism when, in reality, the peg depended on hidden market support.

Authorities also argue that Kwon repeatedly misrepresented how “decentralized” and “independent” Terraform’s ecosystem really was.
In early 2022, Kwon launched the Luna Foundation Guard (LFG), a reserve fund that was supposed to defend UST’s peg using billions of dollars’ worth of assets, including Bitcoin. The public communications were made to focus on the fact that LFG was regulated by an autonomous governing body made of industrial experts but such is not the case, according to prosecutors:
Another aspect of the case that comes out is the way Kwon promised to deceive the investors regarding Terra-based applications:
