I'm sorry for the term I'm going to use on the topic we're talking about; only a fool would believe that person. Everything that that person says is the opposite of what actually happens. Woe to those who believe in that person.
I remember before he said that its holders should sell Bitcoin when its price value was at 17k$, but after what he said, Bitcoin rallied. So those who believed in him sold bitcoin around 17k$ each will be blamed for the belief made in that person. So don't just believe anyone's prediction in this field.
