Major Canadian crypto exchange QuadrigaCX accidentally transferred nearly $500,000 in Bitcoin (BTC) to its cold wallets earlier this month, according to a report published by Ernst & Young on Feb. 12.
The founder of QuadrigaCX, 30-year-old Gerald Cotten, died in December 2018. The exchange has been unable to access its cold wallets since, as Cotten was solely responsible for the wallets and corresponding keys.
