This site is actually a joke with such predictions, and I remember some of old predictions from this site who had been a complete failure. To rely on this kind of predictions really makes no sense and I think that most will agree with that. According to them, the biggest price in the next four years will be 33 000 $ in 2022, and with regard to how much is BTC advanced in its first ten years this is a very unrealistic price.

Of course, it should be mentioned that such predications do not take into account any good or bad events that may occur in the forthcoming period. If they were to be trusted then it would be best to sell our coins now since in next year they predict drop close to 3000$.
