Yes bitcoin drops in this month but before that, bitcoin goes so up high.  In the middle of this month, bitcoin starts dropping a little but it goes back in 17K USD. as the Christmas comes near, that starts dropping much more. It drops until it is around 13K USD. I hope your 7K USD prediction will not happen. it recoved but now it back again in 13k USD range. I expected drop when bitcoin hits 19K USD. But I did not expect that it will drop up to around 13K USD. I think this will continue to happen until this year end then start and continue recovering in 2018. 20K is the prediction of the most of us in here by the next coming year
