Summary

QuadrigaCX was a Canadian cryptocurrency exchange founded in 2013 that collapsed in early 2019 following the death of its CEO Gerald Cotten in India in December 2018. The Ontario Securities Commission concluded in June 2020 that the exchange had operated as a fraud and Ponzi scheme, with Cotten using fictitious balances and customer funds for personal enrichment, causing losses of at least C$169 million across approximately 76,000 affected users.

Overview and Founding

QuadrigaCX (operated through Quadriga Fintech Solutions) was founded in November 2013 in Vancouver, British Columbia, by Gerald Cotten and Michael Patryn. At the time of its collapse, it was considered Canada's largest cryptocurrency exchange by trading volume. The platform allowed users to buy and sell Bitcoin and other digital assets and held funds in both hot (online) and cold (offline) wallets on behalf of its approximately 115,000 registered customers.

Death of Gerald Cotten

Gerald Cotten, age 30, died on December 9, 2018, at Fortis Escorts Hospital in Jaipur, India, where he and his wife Jennifer Robertson had traveled for their honeymoon. According to hospital records, Cotten was admitted on December 8 at 9:45 p.m. IST and suffered two cardiac arrests before dying at 7:26 p.m. the following evening. The hospital cited a diagnosis of septic shock, perforation, peritonitis, and intestinal obstruction; Robertson later stated he died from complications of Crohn's disease, with which he had been diagnosed around age 24. No independent autopsy was performed in India at the time of death. Notably, Cotten signed a new will on November 27, 2018, just twelve days before his death, leaving his estate entirely to Robertson. The combination of a recently updated will, no autopsy, and the subsequent discovery that exchange wallets were empty has fueled persistent but unverified speculation that Cotten staged his death.

Empty Cold Wallets and Missing Funds

Following Cotten's death, QuadrigaCX claimed it could not access approximately C$250 million (approximately US$190 million) in cryptocurrency held in offline cold wallets, because only Cotten possessed the passwords. Ernst and Young (EY), appointed as court monitor and later trustee in bankruptcy, conducted a forensic review and located six cold wallet addresses associated with the exchange. All six were found to be empty and had held no cryptocurrency since April 2018 — more than eight months before the exchange publicly disclosed the access problem. This finding indicated that the narrative of inaccessible cold storage was false: the funds had been removed long before Cotten's death. Of the approximately C$190 million owed to users, roughly C$53 million was tied up in a separate ongoing dispute with the Canadian Imperial Bank of Commerce, and the remainder was in cryptocurrency that could not be located.

OSC Fraud and Ponzi Scheme Findings

In June 2020, the Ontario Securities Commission (OSC) published a comprehensive investigative report concluding that QuadrigaCX was a fraud and that its co-founder and CEO Gerald Cotten had operated it as a Ponzi scheme. The OSC found that Cotten opened at least five fake customer accounts under aliases (including 'Chris Markay,' 'Aretwo Deetwo,' and others) and credited himself with fictitious cryptocurrency and fiat balances, which he then used to trade against real, unsuspecting customers. When crypto asset prices moved against him, he sustained real losses, creating a growing shortfall in customer assets. To cover these shortfalls, he used new customer deposits — the classic structure of a Ponzi scheme. The OSC determined that approximately C$115 million of total losses arose directly from Cotten's fraudulent trading activity, and that he lost an additional C$28 million trading client assets on three external platforms without client authorization or disclosure. Collectively, the collapse caused losses of at least C$169 million to approximately 76,000 investors in Canada and internationally. The OSC also found that a complete absence of internal controls, independent oversight, and proper record-keeping enabled the fraud to persist undetected.

Bankruptcy Proceedings and Creditor Recovery

On February 5, 2019, QuadrigaCX filed for creditor protection under Canada's Companies' Creditors Arrangement Act (CCAA) in Nova Scotia Supreme Court. Ernst and Young was appointed as court monitor. On April 8, 2019, the court appointed EY as Trustee in Bankruptcy, and on April 15, 2019, the company was formally assigned into bankruptcy under the Bankruptcy and Insolvency Act. The case was subsequently transferred to the Ontario Superior Court of Justice (Commercial List) in September 2019. A claims process was established, and a first interim dividend of approximately C$0.13 per dollar of claim value was declared in March 2023. Of the approximately C$215.7 million in liabilities, EY recovered approximately C$28 million in assets for distribution.

Jennifer Robertson Settlement

Jennifer Robertson, Cotten's widow, reached a settlement with the bankruptcy trustee. Under the agreement, Robertson surrendered approximately C$12 million in assets, including real estate properties, a boat, and a Cessna 400 airplane that had been transferred to her or inherited from Cotten's estate. She was permitted to retain more than C$90,000 in cash, her Jeep Cherokee, and her wedding ring. Robertson has publicly stated she was unaware of the fraudulent nature of the exchange's operations during Cotten's lifetime.

Exhumation Request

In December 2019, lawyers representing QuadrigaCX customers filed a formal request with the Royal Canadian Mounted Police (RCMP) to exhume Cotten's remains and conduct an independent autopsy. The stated rationale was to verify both Cotten's identity and the cause of death, given the suspicious circumstances. Robertson's legal team opposed the request, stating Robertson was 'heartbroken' and questioning how an exhumation would assist in asset recovery. As of the available public record, no exhumation had been carried out, and no formal criminal charges have been filed in connection with the QuadrigaCX collapse.

Co-Founder Michael Patryn — Criminal History and Subsequent Actions

QuadrigaCX co-founder Michael Patryn was identified by The Globe and Mail and Bloomberg as Omar Dhanani, a convicted criminal who had been one of 28 individuals arrested for operating an identity theft ring called 'Shadowcrew.' Dhanani pleaded guilty and served 18 months in a U.S. federal prison. He changed his name to Omar Patryn in British Columbia in 2003 and again to Michael Patryn in 2008. Patryn has stated he departed QuadrigaCX in 2016, prior to the period identified in OSC findings as the fraudulent trading period. In January 2022, Patryn was identified as '0xSifu,' the pseudonymous treasury manager of the DeFi protocol Wonderland, triggering that project's collapse after his criminal background became public. In March 2024, British Columbia filed an unexplained wealth order against Patryn, seeking to compel him to explain the origins of approximately C$1 million in cash, 45 gold bars, luxury watches, and jewelry seized from a safety deposit box. In December 2025, British Columbia secured a default judgment forfeiting the assets after Patryn declined to contest the action.

Netflix Documentary

On March 30, 2022, Netflix released 'Trust No One: The Hunt for the Crypto King,' a feature-length documentary directed by Luke Sewell. The film follows a group of QuadrigaCX investors who lost money in the collapse and their efforts, through a self-organized group called 'The Committee,' to investigate the circumstances of Cotten's death and recover their funds. The documentary received mixed reviews: CoinDesk noted it captured the human dimension of the losses and investor frustration but that it leaned into conspiracy framing and raised more questions than it resolved about whether Cotten actually died.
