It feels heavy for bitcoin to reach 20k in 2019, but to reach 10k it seems that it can be achieved, the market is still in poor condition and to make a 20k increase, it will be achieved in 2020-2021.
This year if it will jump at least by 15k then 20k is possible, same with when price approaches increase at least now which seems to be impossible at the moment.
Do not be in haste for some quick jump or some growth first, as you need to realize that this is something that would need to take some time as far as I am concerned. The rate at which a lot of people are just expecting what happened last year to happen all of a sudden again this year, is so funny, but the truth of it all is the fact that you cannot get to see the market just pop up all of a sudden as there is always what they call some little bit of calm even after the storm.
We have been in a downtrend for a while now, so it is a normal thing to note that, this is not something that would just immediately convert to an uptrend, it will develop into it, and no one can actually tell what the price would ever be in the short term or even in the long term.
