Thinking about the worst possible situation will always be our downfall. People on the world always thinks about the worst possible thing because we do live the worst possible situation quite frequently and that's understandable. I am not saying it's impossible to see bad situations but I bet we will have good results too.
So I agree with you, yes there is a chance, you are right but we shouldn't be too light on them neither, we should be careful and consider this as something that is a bit more difficult to handle if we are not careful. I know that it will take some time but it should not be taking this much time in the end, it should be normally considered a boring result and just grow constantly over course of some time.
It is natural to think about the worst possible scenario as if we do and it comes to happen then we would have done something in order to protect ourselves in the case it happens, if we did not do this and the worst scenario came to happen anyway then we will suffer all of its effects, and the current drop on the price of bitcoin is a good example of this, as many were expecting for the 30k resistance to be broken only for the opposite to happen and if someone was using leverage without a stop lose such a drop probably liquidated their account already.
