I think it can still happen, but now is a turning point if we consider the past. Bitcoin is a bit down already, and it can go for stabilization somewhere around $15k-$16k; it might go up again after this correction and reach $20k even before the end of 2020; it might go down and down, like it did the previous time back in 2018.
If you look at all the markets you can see that there is a
small dump across all of them. This is part of a correction and I'm positive that it won't last longer than 1-2 days.
I think the stabilisation following this small correction will be around 17-19K and I think the attempt to reach over 20K is still in sight. Christmas rush is approaching and with restrictions in place people will turn to other ways of investing including crypto.
Needles to say that
I believe there is still hope.
