QuadrigaCX was a Vancouver-based cryptocurrency exchange founded in 2013 by Gerald Cotten and Michael Patryn (later revealed to have a previous fraud conviction under the name Omar Dhanani). QuadrigaCX became one of Canada’s largest crypto exchanges before collapsing spectacularly in early 2019 after the reported death of Cotten — the sole person who allegedly knew the passwords to the exchange’s cold wallets holding $190 million (CAD) in customer assets. The collapse became one of crypto’s most bizarre and suspicious failure stories, with subsequent investigation by the Ontario Securities Commission (OSC) revealing the exchange was effectively a Ponzi scheme rather than a legitimate exchange.
Background
QuadrigaCX grew during the 2017 bull market, processing millions in transactions and serving hundreds of thousands of Canadian users. Cotten operated the exchange with minimal staff, reportedly keeping all important credentials himself. In December 2018, Cotten died in India of Crohn’s disease complications at age 30 — or so the official account states. His widow Jennifer Robertson filed for creditor protection in January 2019, claiming the firm owed $190M to approximately 76,000 users.
What the OSC Found
The Ontario Securities Commission’s 2020 investigation revealed:
| Finding | Detail |
|---|---|
| Fabricated trades | Cotten created fake accounts and fabricated trades to generate assets on the platform |
| Customer funds misused | Cotten used customer funds for personal spending, gambling losses, and real estate |
| The cold wallets were empty | The wallets allegedly holding $190M contained little to no Bitcoin — funds had already been spent |
| Operational fraud from inception | The exchange was never properly solvent; losses were hidden through manufactured trading entries |
The Death Mystery
Significant doubt surrounds Cotten’s death:
- Filed for creditor protection just 12 days after Cotten’s reported death (suggesting knowledge in advance)
- His will was reportedly signed two weeks before the India trip where he died
- Petition to exhume his body was filed by creditors in 2019; it remains unresolved
- Co-founder Michael Patryn’s criminal history was discovered after the collapse
