QuadrigaCX — CEO Died with the Keys, $190 Million Frozen

QuadrigaCX, Canada’s largest cryptocurrency exchange at its peak, collapsed in early 2019 after co-founder and CEO Gerald Cotten died in Jaipur, India on December 9, 2018, leaving 115,000 users locked out of wallets holding approximately C$215 million in cryptocurrency and cash. The platform had operated since December 2013, growing to serve hundreds of thousands of registered users across Canada and internationally. The exchange announced Cotten’s death publicly on January 14, 2019, claiming no other employee possessed the encryption passwords to the cold wallets. The exchange filed for creditor protection under Canada’s Companies’ Creditors Arrangement Act on January 31, 2019.

Subsequent investigation by the Ontario Securities Commission, completed in April 2020 and published June 11, 2020, determined that what appeared to be a tragic accident was in fact a long-running fraud. Cotten had been operating a Ponzi scheme for years: he created accounts under aliases, credited himself with fictitious cryptocurrency balances, traded against his own customers, and covered accumulating losses with incoming client deposits. The OSC calculated that C$169 million of the asset shortfall was attributable to Cotten’s fraudulent conduct, with approximately C$115 million arising directly from his fake-balance trading. No criminal conviction has ever been recorded — Cotten is officially deceased — and no assets approaching the scale of the losses have been recovered.

The 115,000 users who held active balances at collapse were predominantly ordinary Canadian retail investors, many of whom had deposited savings, retirement funds, and money exchanged from national currency into Bitcoin and Ethereum on a platform that projected institutional legitimacy. As of May 2023, creditors received an interim distribution of 13 cents on the dollar, calculated on claims worth C$303.1 million — a figure that reflects continuing losses in real terms as cryptocurrency prices moved over the intervening years.
