Definitely bitcoin will be come at $2000, But now it is not a right time for bitcoin to come at this price in this year, I mean in 2017, it is hard for bitcoin to come achieve at this price $2000.
But i could predict easily that in this year 2017, bitcoin definitely will be come at $1400 to $1500. But about the 2018, may be in the end of 2018, bitcoin will be reached at $1800 to $2000.
