$20k may even be possible by the end of 2017 now.
Due to the arrival of institutionalised money.
No, It's too hard. I don't think that bitcoin can reach the 20k$ by the end of 2017. I think that you are too optimistic about bitcoin. By the way, I think that bitcoin will reach the 8.500 or maybe the 9000$ in the end of this year, Also when we talk about the 20k$, I believe that will happend next year.
You have to understand how much money Wall street will bring in.
Did you not see the announcement from CME on Bitcoin futures?
There will be a correction at the SWx2 fork but then its on. $10k by end of year minimum.
