bitcoin is five years time in my opinion there will be a lot of hard forks from the original bitcoin blockchain and the value of bitcoin would increase by 300 percent today's price. if transaction's speed and price remains the same, bitcoin's not improving and maybe the price wont grow that much
I'm very optimistic about future of bitcoin.
2 years ago value of bitcoin was only $200 and last year around $700.
Today, even with this recent big drop, btc price is still much higher than last year.
So, regardless of the occasional higher falls, bitcoin prices are constantly increasing every year.
I expect that such trend will continue and that we will reach price of $10 000 very soon

In five years from now bitcoin will be super expensive, it will reach anywhere between $40k - $50k.
If you look at the present bitcoin growth this year 2017 - bitcoin gained over 800% increased in value this year alone.
So, if bitcoin can manage to grow by 500% every year in 5 years, then the value of bitcoin could definitely reach what I was saying.
