Your prediction bro is to high for the upcoming year 2018 maybe 10k is enough that is 5 times for the other prediction value? Cause if bitcoin reach that value its to hard to earn even satoshi think . Now a days even 6k is to hard to reach also. Haha and all of the investor will be rich in year 2018 if that prediction will happened.  But its impossible to reach cuase its to high . I have a prediction also it will reach 7-8k but it will fall again deeply and back to 4-5k . But i wish that it will become stable in the next year even 7k is enough for me. .
