CEO dies holding only passwords to customers' $145-mn cryptocurrency

Digital-asset exchange QuadrigaCX can't retrieve around $145 million in Bitcoin, Litecoin, Ether and other cryptocurrencies held for its customers after its CEO Gerald Cotten, the only person with access to passwords, died. Cotten died aged 30 on December 9 from complications of Crohn's disease. To avoid being hacked, Cotten had moved majority of digital coins into cold storage.
