“Unless they enacted remarkably different practices in the last year, I would be very surprised to learn of a cold storage ether address based on what I’ve seen so far,” Monahan told CoinDesk. “Almost all of the largest transactions are either sent to exchanges or amongst three ‘primary’ addresses (1, 2, 3). I haven’t seen anything indicating a large reserve or cold storage mechanism being used on the Ethereum chain.” All told, the analysis of QuadrigaCX’s ether wallets doesn’t look optimistic for the users who have their funds stuck on the exchange, with cryptos bleeding in the direction of other exchanges.  Kraken CEO commented on the situation in Twitter, writing "thousands of wallet addresses known to belong to QuadrigaCX” and the team is now investigating “the bizarre and, frankly, unbelievable story of the founder’s death and lost keys.”
