Re: The question is when: Bitcoin at $2000. 2017 or 2018?
I think it will happen in 2017 
I think it already happen, and it happen too fast I think you didn't notice it, try and check the price more often and you would realize the value now of bitcoin it is really outstanding that it reached the expected mark value that is $2000 and a lot are now expecting the price to really goes up a bit more and I think when it reached the $2500, I speculate that it is safe to really stay in the $2000 mark value,
The value mark has been occuring already and the latest prediction for now is at 2500$-3000$ and theirs a huge possibilities that we can see the price to reach that since theirs still some positive aspects and provabilities that this current rally will still continue to soar. And we should speculate for more since I think fearless prediction of individual can truly help for reaching some good happenings for it.
