The SEC simultaneously sought emergency relief on grounds that the scheme was an ongoing fraud. On September 28, 2015, Judge R. Gary Klausner granted the SEC's request for an asset freeze and appointed Thomas A. Seaman as temporary receiver over USFIA and the related entities. At the time of the initial complaint, the SEC alleged that USFIA had raised more than $32 million from investors inside and outside the United States since at least April 2013. In March 2017, the court entered a final judgment ordering Steven Chen and related entities to pay $51.9 million in disgorgement of ill-gotten gains, $3.8 million in prejudgment interest, and a civil penalty of $16.7 million, for a total civil judgment of approximately $74 million.","heading":"SEC Enforcement Action and Asset Freeze","severity":"critical","sources":[{"credibility":1,"name":"SEC Press Release 2015-227: SEC Halts $32 Million Scheme That Promised Riches From Amber Mining","type":"regulatory","url":"https://www.sec.gov/newsroom/press-releases/2015-227"},{"credibility":1,"name":"SEC Litigation Release LR-23378: Steve Chen, et al.","type":"regulatory","url":"https://www.sec.gov/enforcement-litigation/litigation-releases/lr-23378"},{"credibility":2,"name":"CoinDesk: Gemcoin Ponzi Scheme Operator Hit With $74 Million Judgment (March 2017)","type":"news_article","url":"https://www.coindesk.com/markets/2017/03/15/gemcoin-ponzi-scheme-operator-hit-with-74-million-judgment"}]},{"content":"USFIA and Steve Chen operated in two overlapping phases. In the initial phase, beginning at least in July 2013, investors were recruited through a multi-level marketing structure and told that USFIA owned large and valuable amber mines in Argentina, the Dominican Republic, Mexico, and the United States. Investors paid between $1,000 and $30,000 each for USFIA membership or investment packages, with higher returns promised for recruiting additional participants. Chen and his associates falsely claimed that a lucrative initial public offering for USFIA was imminent, which never occurred. In September 2014, the defendants pivoted and claimed to convert existing investors' holdings into 'Gemcoins,' a virtual currency they described as secured by the company's amber and gemstone holdings. Promotional claims included assertions that Gemcoin's backing exceeded $15 billion, that the tokens had 'zero chance of devaluation,' and that they would grow exponentially every two months. Approximately 2,000 ATM platforms were falsely claimed to allow conversion of coins to currency. When independent appraisers examined the chunks of amber that USFIA physically distributed to investors, the amber proved to be nearly worthless fossilized tree sap. The SEC found no evidence of any legitimate gemstone mining business; between July 2011 and May 2015, approximately $32 million entered USFIA's primary bank account, of which approximately $19 million arrived via Asian wire transfers and $5.7 million through U.S. checks, with no significant legitimate business revenue. Court-appointed receiver Thomas Seaman's February 2016 report concluded that USFIA was purposefully designed to defraud investors from inception and that 'there is no indication there was any legitimate Gemcoin or other viable business operated by the Receivership Entities.'","heading":"Scheme Mechanics and False Claims","severity":"critical","sources":[{"credibility":1,"name":"SEC Press Release 2015-227: SEC Halts $32 Million Scheme That Promised Riches From Amber Mining","type":"regulatory","url":"https://www.sec.gov/newsroom/press-releases/2015-227"},{"credibility":2,"name":"BehindMLM: SEC — USFIA's GemCoin a $32 million dollar Ponzi scheme","type":"news_article","url":"https://behindmlm.com/mlm/regulation/sec-usfias-gemcoin-a-32-million-dollar-ponzi-scheme/"},{"credibility":2,"name":"The Merkle: Further Details Uncovered in $32 Million Gemcoin Ponzi Scheme (receiver findings)","type":"news_article","url":"https://themerkle.com/further-details-uncovered-in-32-million-gemcoin-ponzi-scheme/"},{"credibility":2,"name":"CoinDesk: GemCoin Investors Seek $100 Million in Class Action Lawsuit","type":"news_article","url":"https://www.coindesk.com/markets/2015/10/08/gemcoin-investors-seek-100-million-in-class-action-lawsuit"}]},{"content":"Parallel to the SEC civil action, the U.S. Department of Justice, U.S. Attorney's Office for the Central District of California, pursued criminal charges against Chen and associates. Leonard Stacy Johnson, 54, of Huntington Beach, who served as USFIA's Vice President of Investor Relations and worked at Chen's direction to promote USFIA and Gemcoin, pleaded guilty in July 2019 to one count of tax evasion and one count of making a false statement on an immigration document. Johnson cooperated substantially with the government; his sentencing guideline offense level was reduced from 13 to 8 as a result, and he was sentenced to two years probation and ordered to pay $45,871 in restitution. Steve Chen himself agreed to plead guilty in February 2020 to one count of conspiracy to commit wire fraud and one count of tax evasion. At the time of his plea, the government's evidence showed that Chen had obtained approximately $147 million from approximately 72,000 victims between July 2013 and September 2015, constituting one of the largest pyramid schemes ever prosecuted in the Central District of California. On the tax evasion count, Chen had reported gross income of $138,015 for tax year 2014 when his actual income was approximately $4,816,193, resulting in $1,885,094 in unpaid taxes. On January 10, 2021, Judge John F. Walter sentenced Chen to 120 months (ten years) in federal prison — the mandatory minimum under the plea agreement — and ordered him to pay $1,885,094 in restitution to the IRS. A separate restitution hearing for victim investors was scheduled for July 16, 2021.","heading":"Criminal Prosecution and Sentencing","severity":"critical","sources":[{"credibility":1,"name":"DOJ USAO-CDCA: Bradbury Man Sentenced to 10 Years in Prison for Leading Role in $147 Million Mining and Digital Currency Fraud","type":"regulatory","url":"https://www.justice.gov/usao-cdca/pr/bradbury-man-sentenced-10-years-prison-leading-role-147-million-mining-and-digital"},{"credibility":1,"name":"DOJ USAO-CDCA: San Gabriel Valley Man Agrees to Plead Guilty to Conspiracy and Tax Evasion Charges in $147 Million Mining and Digital Currency Fraud","type":"regulatory","url":"https://www.justice.gov/usao-cdca/pr/san-gabriel-valley-man-agrees-plead-guilty-conspiracy-and-tax-evasion-charges-147"},{"credibility":2,"name":"CoinDesk: GemCoin Founder Sentenced to 10 Years for $147M Crypto Scheme (January 2021)","type":"news_article","url":"https://www.coindesk.com/markets/2021/01/11/gemcoin-founder-sentenced-to-10-years-for-147m-crypto-scheme"},{"credibility":2,"name":"BehindMLM: Leonard Johnson avoids prison for USFIA Gemcoin fraud","type":"news_article","url":"https://behindmlm.com/companies/usfia/leonard-johnson-avoids-prison-for-usfia-gemcoin-fraud/"}]},{"content":"The scheme disproportionately targeted Chinese and Chinese-American investors, particularly within Southern California's San Gabriel Valley communities, including the city of Arcadia. USFIA's offices were located in Arcadia, a city with a large Chinese-American population. Promotional events were conducted in Chinese-language settings and distributed to Chinese-language media. A $100 million class action lawsuit filed in October 2015 at Los Angeles Superior Court by the Liu Law Group on behalf of approximately 3,000 plaintiffs stated that the scheme 'defrauded thousands of Chinese and Chinese-American investors beginning in 2014.' Of the approximately $32 million tracked in USFIA's primary bank account during the SEC investigation period, approximately $19 million arrived via Asian wire transfers. The scheme's total victim count reached approximately 72,000 globally, with many investors based overseas. John Wuo, a former mayor and then-sitting Arcadia City councilman, appeared at USFIA events and made public endorsements of the scheme; he received approximately $1.8 million from USFIA according to subsequent disclosures. Wuo resigned from the city council in October 2015 following media scrutiny and received a $2,000 fine in 2016; he was not criminally charged in connection with the scheme.","heading":"Victim Demographics and Community Targeting","severity":"high","sources":[{"credibility":2,"name":"CoinDesk: GemCoin Investors Seek $100 Million in Class Action Lawsuit","type":"news_article","url":"https://www.coindesk.com/markets/2015/10/08/gemcoin-investors-seek-100-million-in-class-action-lawsuit"},{"credibility":2,"name":"BehindMLM: John Wuo, former Arcadia mayor, received $1.8 million from USFIA","type":"news_article","url":"https://behindmlm.com/mlm/regulation/john-wuo-former-arcadia-mayor-rcvd-1-8-mill-from-usfia/"},{"credibility":2,"name":"BehindMLM: SEC — USFIA's GemCoin a $32 million dollar Ponzi scheme","type":"news_article","url":"https://behindmlm.com/mlm/regulation/sec-usfias-gemcoin-a-32-million-dollar-ponzi-scheme/"}]},{"content":"Steve Chen controlled USFIA Inc. and at least six other California-based companies sharing the same Arcadia address, all of which were named in the SEC complaint. USFIA operated as the domestic subsidiary of Alliance Financial Group (AFG). Chen also held interests in two real estate trusts, a consulting business, and a golf course holding company; the $74 million civil judgment covered Chen and these related entities collectively. Other named defendants in the class action lawsuit included John Wuo, Solomon Yang, Leonard Johnson, John Zhang, and Kun Jiang, as well as four corporations: USFIA, UCCA, AmKey Inc., and Alliance Financial Group. The receiver, Thomas Seaman, found that aside from income from hotel and rental properties, the entities had no significant source of income other than money raised from investors, confirming the absence of any legitimate underlying business.","heading":"Corporate Structure and Related Entities","severity":"high","sources":[{"credibility":1,"name":"SEC Press Release 2015-227","type":"regulatory","url":"https://www.sec.gov/newsroom/press-releases/2015-227"},{"credibility":2,"name":"CoinDesk: GemCoin Investors Seek $100 Million in Class Action Lawsuit","type":"news_article","url":"https://www.coindesk.com/markets/2015/10/08/gemcoin-investors-seek-100-million-in-class-action-lawsuit"},{"credibility":2,"name":"CoinDesk: Gemcoin Ponzi Scheme Operator Hit With $74 Million Judgment","type":"news_article","url":"https://www.coindesk.com/markets/2017/03/15/gemcoin-ponzi-scheme-operator-hit-with-74-million-judgment"}]},{"content":"Steve Chen, age 65, died on November 19, 2022 while serving his ten-year federal prison sentence. The Bureau of Prisons' inmate search records confirmed his death. His cause of death has not been publicly disclosed. Chen had been sentenced in January 2021 and would have been approximately two years into his sentence at the time of death. Chen had also been known by the aliases 'Li Chen' and 'Boss,' and was noted by observers for theatrical behavior at company events, including portraying himself as the 'Sheriff of GemCoin' at public appearances with security personnel dressed as police officers.","heading":"Death of Steve Chen While Incarcerated","severity":"medium","sources":[{"credibility":2,"name":"BehindMLM: USFIA Ponzi founder Steve Chen dies in prison","type":"news_article","url":"https://behindmlm.com/companies/usfia/usfia-ponzi-founder-steve-chen-dies-in-prison/"}]},{"content":"Following the September 2015 asset freeze, court-appointed receiver Thomas Seaman managed recovery efforts for victim investors. By February 2016, Seaman had recovered approximately $21.9 million in investor funds. The total losses were ultimately established at approximately $147 million through the criminal proceedings, meaning the recovery represented a fraction of total investor harm. Offshore entities connected to the scheme remained under investigation as of early 2016 reports. The civil judgment of approximately $74 million entered in March 2017 included $51.9 million in disgorgement plus interest and a civil penalty, though recovery from Chen personally remained uncertain given the dissipation of funds.","heading":"Asset Recovery","severity":"medium","sources":[{"credibility":2,"name":"The Merkle: Further Details Uncovered in $32 Million Gemcoin Ponzi Scheme","type":"news_article","url":"https://themerkle.com/further-details-uncovered-in-32-million-gemcoin-ponzi-scheme/"},{"credibility":2,"name":"CoinDesk: Gemcoin Ponzi Scheme Operator Hit With $74 Million Judgment","type":"news_article","url":"https://www.coindesk.com/markets/2017/03/15/gemcoin-ponzi-scheme-operator-hit-with-74-million-judgment"}]}],"sources_used":[{"credibility":1,"name":"SEC Press Release 2015-227: SEC Halts $32 Million Scheme That Promised Riches From Amber Mining","type":"regulatory","url":"https://www.sec.gov/newsroom/press-releases/2015-227"},{"credibility":1,"name":"SEC Litigation Release LR-23378: Steve Chen, et al.","type":"regulatory","url":"https://www.sec.gov/enforcement-litigation/litigation-releases/lr-23378"},{"credibility":1,"name":"DOJ USAO-CDCA: Bradbury Man Sentenced to 10 Years in Prison for Leading Role in $147 Million Mining and Digital Currency Fraud","type":"regulatory","url":"https://www.justice.gov/usao-cdca/pr/bradbury-man-sentenced-10-years-prison-leading-role-147-million-mining-and-digital"},{"credibility":1,"name":"DOJ USAO-CDCA: San Gabriel Valley Man Agrees to Plead Guilty to Conspiracy and Tax Evasion Charges in $147 Million Mining and Digital Currency Fraud","type":"regulatory","url":"https://www.justice.gov/usao-cdca/pr/san-gabriel-valley-man-agrees-plead-guilty-conspiracy-and-tax-evasion-charges-147"},{"credibility":2,"name":"CoinDesk: GemCoin Founder Sentenced to 10 Years for $147M Crypto Scheme (January 2021)","type":"news_article","url":"https://www.coindesk.com/markets/2021/01/11/gemcoin-founder-sentenced-to-10-years-for-147m-crypto-scheme"},{"credibility":2,"name":"CoinDesk: Gemcoin Ponzi Scheme Operator Hit With $74 Million Judgment (March 2017)","type":"news_article","url":"https://www.coindesk.com/markets/2017/03/15/gemcoin-ponzi-scheme-operator-hit-with-74-million-judgment"},{"credibility":2,"name":"CoinDesk: GemCoin Investors Seek $100 Million in Class Action Lawsuit (October 2015)","type":"news_article","url":"https://www.coindesk.com/markets/2015/10/08/gemcoin-investors-seek-100-million-in-class-action-lawsuit"},{"credibility":2,"name":"BehindMLM: USFIA Ponzi founder Steve Chen dies in prison","type":"news_article","url":"https://behindmlm.com/companies/usfia/usfia-ponzi-founder-steve-chen-dies-in-prison/"},{"credibility":2,"name":"BehindMLM: Leonard Johnson avoids prison for USFIA Gemcoin fraud","type":"news_article","url":"https://behindmlm.com/companies/usfia/leonard-johnson-avoids-prison-for-usfia-gemcoin-fraud/"},{"credibility":2,"name":"BehindMLM: John Wuo, former Arcadia mayor, received $1.8 million from USFIA","type":"news_article","url":"https://behindmlm.com/mlm/regulation/john-wuo-former-arcadia-mayor-rcvd-1-8-mill-from-usfia/"},{"credibility":2,"name":"BehindMLM: SEC — USFIA's GemCoin a $32 million dollar Ponzi scheme","type":"news_article","url":"https://behindmlm.com/mlm/regulation/sec-usfias-gemcoin-a-32-million-dollar-ponzi-scheme/"},{"credibility":2,"name":"The Merkle: Further Details Uncovered in $32 Million Gemcoin Ponzi Scheme","type":"news_article","url":"https://themerkle.com/further-details-uncovered-in-32-million-gemcoin-ponzi-scheme/"},{"credibility":2,"name":"Finance Magnates: Founder of $147M Crypto Ponzi Scheme Gets 10-Year Prison Sentence","type":"news_article","url":"https://www.financemagnates.com/cryptocurrency/news/founder-of-147m-crypto-ponzi-scheme-gets-10-year-prison-sentence/"},{"credibility":2,"name":"LeapRate: Founder of $147 million GemCoin crypto Ponzi scheme sent to prison for 10 years","type":"news_article","url":"https://www.leaprate.com/financial-services/ponzi-scheme/founder-of-147-million-gemcoin-crypto-ponzi-scheme-sent-to-prison-for-10-years/"},{"credibility":2,"name":"The Register: Alleged $32m Gemcoin crypto-bucks scam busted by Feds","type":"news_article","url":"https://www.theregister.com/2015/10/02/gemcoins/"},{"credibility":3,"name":"Cryptopolitan: Gemcoin founder confesses to $147M fraud","type":"news_article","url":"https://www.cryptopolitan.com/gemcoin-founder-pleads-guilty/"}],"summary":"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 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.
