That's right, right now, when the price of bitcoin is in such a big decline. If it were me, I'd buy it!
Wait for 20K-25K in the next 15 day's.
If Bitcoin price revisit that price area, I'm sure that it will not stay long on that level because it's on critical level. It will go deeper than that and we will see the long bloodbath on crypto. But I'm sure going that level will be difficult since manipulation is strong while Institutional investors accumulate above that price. Its either it will go more deeper or reach new ATH.
