Well man I don't think 2k$ is possible now that the price of bitcoin is sitting at 668.2$. IMO It will sit at 750$ in the best in the coming block halving that is near because I don't think it will rise more now that halving is near.
$2000 is possible in January 2018. It will not be so high in January 2017. The price could be around $1000 then.
I think we will see 2k in january 2017 for sure
Maybe at the end of this year but sure for next one
I dont know, 2k it seems too high for such a short interval.
