Chart from 2014, when Bitcoin was $300, predicted price of $10k for today Nov 22nd, 2017.
We're at $8,200. (If we add Bitcoin Cash and Gold prices, we'll get close to $10k).
Next milestone on chart: $100k in summer 2021. And next: $1M in 2027.

Maybe it will happen but we don't know when it will happen because as of now we are facing a down trend or bear market so no one can tell if after years we hit a 1million per bitcoin.
