QuadrigaCX: CEO Dies Taking $190 Million in Customer Crypto to His Grave
What happened
QuadrigaCX, Canada's largest crypto exchange with 363,000 customers and ~$250M in assets, filed for creditor protection in February 2019. CEO Gerald Cotten had died in India, aged 30, allegedly taking sole custody of private keys to cold wallets holding $190M in customer assets. A subsequent OSC investigation found Cotten had operated the exchange as a fraud from at least 2016: trading against his own customers using fake accounts, using new deposits to pay withdrawals, and fabricating trades. The cold wallets existed and were empty.[1]
What went wrong
QuadrigaCX had no corporate governance, no external audits, and no technical redundancy. One person held sole custody of private keys to hundreds of millions in customer assets. The OSC found Cotten had created fake accounts under aliases to trade fictitious crypto balances against real customer orders. The exchange was effectively a Ponzi scheme: customer withdrawals in its final months required constant new deposits. Customer deposits had been spent or lost by Cotten through personal trading.[1]
Lesson learned
Cryptocurrency exchanges holding customer assets are custodians, subject to the same fiduciary obligations as traditional financial institutions. Single points of failure in custody are unacceptable. External audits of cold wallet holdings are the minimum standard. The QuadrigaCX case demonstrates how opacity, lack of regulation, and customer trust in a charismatic founder create conditions for fraud.
