Why do you think I'm paranoid? It's my best guess. Despite my tender years I have seen many speculative bubbles in lots of asset classes and have traded them on a private and professional basis.

I agree there are plenty of people in bitcoin ready to be 'the greater fool' [1] but that's only if it fails... they will be self assured visionaries otherwise...
