You may be panicing to sell all your crypto right now, but now may not a good idea and you should hold on to at least some of your coins. Remember a month or two ago when bitcoin crashed from 20000 to 6000 in a series of just weeks, well it sprang back up to 12000. Whoever decided to chicken out early made a BAD choice. The same is happening now, as bitcoin has just crashed to around 7000, although it could be possible to crash to 0, it is not likely, and I would advise you to hold on to at least some of your crypto, as it will probably spring up again real soon.
Note: In reality, its what you decide to do with crypto, good luck out there.
