He tweeted this few days before his suspicious death:
The US believes I have hidden crypto. I wish I did but it has dissolved through the many hands of Team McAfee (your belief is not required), and my remaining assets are all seized. My friends evaporated through fear of association.
I have nothing.
Yet, I regret nothing.
We really don't know the truth. What's the point of his tweet? Maybe he is telling the truth that he don't have any hidden crypto. He already passed all the access to the someone or it's really seized. Or maybe his friends have it that's why they're all gone. I hope they will just take care of what McAfee left.
