I believe bitcoin will test and overpass ATH as a psychological target too besides the fact that big money is already in the game. As I don't see any valid reason why the price may significantly decline I expect it will be higher than $20k by the end of 2020 unless some total crash happens on all market and whales start dumping their bags which I really doubt.
remember that the end of the year is still more than a month and it could possibly happen because if we see bitcoin making some unusual maneuvers. he can go down drastically and go up with a matter of days, even have made a sharp increase in just a day.
so the possibility of going down again could happen and this is the way bitcoin is profitable to play short-term investments that have rarely been done so far.
Price predictions that may be worth bearing at the end of the year, around $ 16K are already good value to continue in the following year.
