It will reach $20000 somewhere next week. At the end of this year it will most likely be closer to $25000 if not more.
I also voted by the end of 2017 in the poll, and I have no doubt the pump will continue up higher than $20k but I'm not sure yet sure if it will reach $25k. The CME is the big wildcard here it could either bring bitcoin to a trillion dollar market cap very fast or it could crash it hard.
