GERRY COTTEN, 30, was in India opening an orphanage, when he passed away taking the company’s passwords to his grave. Now Quadriga CX, based in HALIFAX, Nova Scotia, is in crisis mode. His wife is unable to find the passwords or keys that would unlock the wallets, worth about $250-million. “Cold wallets” are essentially offline storage systems that protect funds from hacking and theft. They’re locked solid without passwords. The company has about $375,000 in cash while owing the equivalent of $250-million to about 92,000 users. Mr. Cotten died on December 9th with complications from Crohn’s disease.
