Drop to 90%. I never read news from such people who anti-Bitcoin.
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.
Obviously, when his prediction doesn't work then he will say the reason bla bla bla. We already know Bitcoin has a volatile nature, price dependence is based on demand-supply market. With making like this Fud news, they wants to create panic in the market.
