I think, the current price of bitcoin is still far from the price at the end of 2017, but bitcoin has the potential to reach that price again because bitcoin prices are difficult to predict and anything can happen
For me that won't happen in this year and we will need to wait for that unfortunately till 2019, but there are some possitives connected to that like we have some months more to invest in bitcoin when its price is still very low
In my opinion it is not possible. How the price will reach to $20000 tomorrow? There is a huge difference between the price of today and $20000. It will take long time, but I am sure that it will reach to that point in the long run. The market today is red and demand for bitcoin is very low because of the loses made by investors. Now they are ambiguous to invest or not.
