As per Crypto researcher ZachXBT, five wallets belonging to the defunct Canadian Crypto exchange QuadrigaCX have moved around $1.7 million worth of Bitcoin after years of dormancy. Blockchain records reveal that these wallets had not sent BTC since April 2018. QuadrigaCX declared bankruptcy in Apr. 2019 following the death of its CEO, Gerald Cotten, who had the private keys to the exchange's wallets.
