Do Kwon was sentenced to 15 years for fraud tied to the TerraUSDLuna collapse, which wiped out about $40B in 2022. Prosecutors said he misled investors about how UST held its $1 peg and secretly propped it up through a trading firm. He agreed to an $80M fine and a crypto ban under a $4.55B SEC deal and may seek transfer after serving half his U.S. term.
