Why bitcoin start going down and down will it goes below 10000$?
I think its because today is end of the year going to christmas season and new year i think that was the reason why bitcoin was dump but after this bitcoin will go back to normal again.
I agree with you, by the end of 2017, our chance to invest in bitcoin, Because the price of the end of this year with the price of dump, then next year 2018 we will get more profit, So we better bit hold bitcoin for long term.
