Cotten, co-founder and CEO of Quadriga , died of complications in December 2018 arising from Crohn's Disease while traveling in India, the company said on Facebook . At the time, Quadriga -- once Canada's biggest cryptocurrency exchange -- said it was unable to gain access to his digital assets. Cotten's death plunged Quadriga into crisis and left it struggling to figure out how to refund more than 100,000 users of the currency. Many of the digital currencies held by Quadriga are stored offline in accounts known as "cold wallets," a way of protecting them from hackers. Cotten was the only person with access to the wallets, according to the company.
