I'd like to be optimistic for what I've seen so far this year.
I suspect in April 2018 the price should be around 5000-6000 if not more.
It can also go down depending on forks, SegWit, etc... But I rather keep positive!
The price of bitcoin could go down when the fork takes place as big investors might pull their funds and might wait till everything is over and it is a really crucial time for traders to see how these sort of things will play out in the coming weeks.I am sure if there is any correction ,it will recover with time.
