I dont think it will happen exactly what you are saying in the op..It can happen the opposite of that..Now a days every country is becoming aware of bitcoin's potential ,so why would they ban such a good currency? Sorry but I dont agree with your thoughts..
We really can't if there's a big crash coming or there's none. As long as the good things that are happening with bitcoin is reliable and true.
Then we don't need to be worried about op says about a big crash. Because the price now is really going up and for sure no reason for it to become lower.
the good things are happening to bitcoin now and for the last few months. The recent price crash is not worrying.
