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

We cannot really predict the future of bitcoin five years from now, but we can rely on statistical records of bitcoin annually. It can give us a track forecast of what could happen to bitcoins value in few couple of years. As we can see, the value of bitcoin seems to replicate and dominate its value from the previous year. If the trend continuous, it is surely a brighter five years ahead for bitcoin.
