Thats a make me a hero prediction. If it happens hes the big hero. If it doesnt happen no one will remember he said it. If they do remember he can just say it might take a little longer do to bla bla bla.
I agree with you if he is right about his prediction he is a hero but if not going to happen then he is just a waste.
Also no one can predict bitcoin value if it is going to decrease or increase and no one can control the price of bitcoin. The funny thing about it he already predicted the price of bitcoin withouth any basis so its just a word came from mouth and nothing gonna happen.
