The actual BTC price is above 18600$ and it is expected to keep rising, so this milestone is already done this year, before the end of 2017. Maybe even it will reach the $20k before the Christmas. We just need to hold and watch the price going up.
The most accurate prediction for bitcoin was breaking $20,000 this year and we're almost there. We're very close to $19,000 then Christmas will come to take bitcoin to higher regions.
