anchored·2Fy2AF…Eke7Summary
Gemcoin was a fraudulent cryptocurrency launched in September 2014 by Steve Chen through his company US Fine Investment Arts (USFIA), operating out of Arcadia, California. The scheme falsely claimed that Gemcoin tokens were backed by billions of dollars in amber and gemstone mine holdings in the Dominican Republic, Argentina, Mexico, and the United States; those mines did not exist. The SEC filed fraud charges and obtained asset freezes in September 2015 when at least $32 million had been raised; a subsequent court-appointed receiver and DOJ criminal prosecution ultimately established total investor losses of approximately $147 million from around 70,000 victims, predominantly Chinese and Chinese-American investors. Steve Chen pleaded guilty in 2020 to conspiracy to commit wire fraud and tax evasion, was sentenced to ten years in federal prison in January 2021, and died in custody on November 19, 2022.
