In the last few days bitcoin plays around 16K USD up to 19kUSD, but starting yesterday bitcoin is down up to 14K USD. I think this is the major fall. There are still eight (8 ) days before this year end. I still hope that bitcoin will recover and continue recovering until early January. Every week bitcoin’s direction changes so there’s a possibility.
By the middle of 2018, I think its price is already in the range of 20K USD. Everybody expects that bitcoin will reach 20K USD in first quarter of 2018 so as I. By the end of 2018, I am thinking about 23-25K USD. but my prediction may change according to what is going happen next year.
