If you think you are good in cracking passwords, try your luck on this one. Its a major exchange site in Canada called Quadriga. It's really surprising that only 1 person holds the key to a business like this.
Maybe they can offer you a good reward if you are able to unlock the password on their exchange site where funds we're transferred to a dead guys wallet.
Might have some luck with this given the opportunity but I doubt that's what actually happened. I've been following the story and it's a really suspicious situation overall.
