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.

Well based on my observation, bitcoin will increase in the future but still it is so unpredictable because sometimes the value of it decrease. I guess that the highest price of the bitcoin is 45K dollars. But who knows, maybe after 10 years it will reach $1 Million.
