I dont know how high it will go but that is how low it will go. Just a humble call made purely via pattern extrapolation. Since you so strongly believe it will not happen, that is exactly why it's going to happen. I have no further arguments.
Pattern extrapolation? Are you taking as reference the gradual decline of bitcoin after the pump in December 2013? That has been one of the most banal "predictions" I've heard relatively often, as if the conditions of the bitcoin market were similar to those of the time.
It is true that nobody knows what the future will bring, but even if the price were to fall to $3,000 by the end of this year, it would still be a splendid year for bitcoin, with a growth of 200% over last year.
