Stefan He Qin is an Australian national who founded and operated two cryptocurrency hedge funds — Virgil Sigma Fund LP and VQR Multistrategy Fund LP — between 2016 and 2020, fraudulently raising approximately $90 million from over 100 investors by fabricating returns and misrepresenting fund strategy. He siphoned investor assets for personal use, attempted to raid a second fund to cover losses, and was arrested after SEC intervention in December 2020. Qin pleaded guilty to federal securities fraud in February 2021 and was sentenced to 90 months in prison in September 2021, making his case one of the largest individual crypto fraud prosecutions prior to the FTX collapse.
