The founder of major Canadian crypto exchange QuadrigaCX, Gerald Cotten, may have stored the exchange’s private keys on paper in a safety deposit box, Bloomberg reported on Feb. 15.
In an interview on the “True Bromance Podcast” in February 2014, Cotten warned of the danger of losing keys to cold wallet storage systems, and thus losing access to the assets stored on them. “Even the U.S. government, with the biggest computers in the world, could not retrieve those coins if you’ve lost the private key. It’s impossible to retrieve those," Cotten said.
