It is still mysterious what will bring 2020 to bitcoin, make any prediction about the price what it will be by 2020, in fact very hard for anybody to tell the exact price but looking over the growth chart than it looking it will be around $9000 - $12000 as per my personal thinking.
of course it is really hard to predict what the prices of the bitcoin is going to be in the near future, i believe we might reach way bigger heights at like 50000 dollar per bitcoin
For the exact price is very difficult to predict because bitcoin continue to fluctuate and are affected by the situation. We're not in bitcoin on what the next 2 years and we could not get in bitcoin will rise or fall. But I believe bitcoin will continue to rise and many will adopt in 2020. Bitcoin will get to the heart of society.
