If nobody is buying cryptocurrency, then the price can as well crash to zero but it is impossible. There are much more sellers than buyers and everyone can clearly see that at the moment. This is probably because some potential buyers feel that the price may still fall further more.
Of course, the price may still fall. The price will go down to $ 1,500, it will stop on this threshold, it will stay for some time and only then it will go up. This is obvious, at least for me.
