I believe bitcoin will at least hit 5000 in 2017. If it can move 50% in 1 month like it just did, it has plenty of time to move + 100% within 6 months.
I believe we moved 100% in 1 month. But yeah I am of the belief that $5000 is reachable in 2017, it all depends on what the smart money decides to do going forward. We could just stay around $2000 moving forward until some big news drop or we could go back down to $1000. It sure feels like it's up in the air at the moment.
Right now its on the downwards side on the graph and hitting with a dump. Lowered near to 300$ in just 1-2 hours and lots of people are going crazy about it. I too hope and wish that it will reach 5k$ one day but i dont think it is a possible future in this year.
