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.

I expect the bitcoin price will hit $ 1M in the year of 2030,the chart shows three years earlier but anyways bitcoin will hit $ 1M in ten years.But anything can be possible in crypto currency so we have to keep alive the bitcoins by keep investing on them then the price will increase by more investors.
