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.
He had a wife, though. They've been on the run together for a long time. I'm not entirely sure he'd trust his money to her, as he, indeed, was more of an introvert. He didn't even call any of his relatives to say goodbye, many of his actions came out as a surprise to the close ones. But I find him as an awesome guy. He is cool.
But, nevertheless, there is a possibility he trusted her more than anyone else.
