John McAfee left his assets to none I guess. He never trust anyone, He never used the antivirus he made. He admitted it in some point. So I guess he never left that wealth also because of trust issue. His coin will be useless forever. Or if someone will discover all his secrets hidden in some vault, that includes all the keys that will lead an access to that. Just my opinion. 
But I find him as an awesome guy. He is cool.

If that's the case then I feel pity for his family. Let's say that they have enough wealth to survive but Mcafee's coin isn't a small amount so it should've been helping his entire family in so many ways. That's actually one of the reasons why we're always advised to trust at least a single person about our personal funds and wallet keys so we'll know where our funds would go if unexpected things happen.
