My best guess is that the fraud angle is most likely. Especially the 'fortunate' emergence of draft contracts showing that the guy has claim to a huge stash of bitcoins (but conveniently he can't access them until 2020). Perhaps he hoped that by appearing to be 'doxxed' it would lend more credence to his claims that he owned/controlled this wealth. A fraudster could get a lot of mileage out of a "I will pay you back later, look I've got all this future wealth" claim.
