Probably
If you have the cash and you want to invest now and go for the long-term, then sure go for it, buying under 20k sounds like a good entry-point. Just remember that you'll try to catch a falling knife, price isn't stable and could go much lower, but hey if you want to buy cheap then at some point you gotta pull the trigger, right? Just understand the risks, once you know what to expect, buy and hodl until X price target
