You are taking a risk coming out with these predictions. Sadly Bitcoin is a $3000-4000 coin without the banks wall street etc. They want Bitcoin at its cheapest price... and this means they will wait another 3-4 weeks if they have to.

Bitcoin went from $780 on Jan 11 2017 to 20k, that is 25x. If the same happens from $5000 it would be $125,000 in December. And this is possible. I dont know if you follow Trace mayer on Twiiter but he has be an investor since 2010 and this is around his prediction.

I am not a financial advisor. make your own decisions.
