Gerald Cotten, the 30-year-old CEO of Canada's largest cryptocurrency exchange QuadrigaCX, dies while traveling in India. Cotten was reportedly the sole person with access to the exchange's cold wallet passwords, leaving approximately $169 million in customer funds locked and inaccessible. The exchange filed for bankruptcy in January 2019. An investigation later revealed Cotten had been misusing customer deposits for years in a Ponzi-like scheme. The case became the subject of a Netflix documentary and remains one of crypto's most bizarre and tragic scandals.
