If Bitcoin really reaches $8000 then people's confidence in crypto currency will decrease a lot. Many people have already lost faith in Bitcoin because of some coin scams.
Many people may panic if Bitcoin drops to $8000. But that doesn't mean all people will begin to leave Bitcoin. For those people who believe in Bitcoin future, it should be a time to buy Bitcoin at a very cheap price. More drops, real Bitcoin holders probably buy more. By the way, I assume only people with a weak trust in Bitcoin who are worried about Bitcoin and think it to drop to $8000. While for people who are confident with Bitcoin, I am sure they never think that Bitcoin price to drop below $10000, even if it is not impossible.
I have seen many people who are worrying a lot about what has not yet happened and this is not a good thing, it is not a healthy thing, and we must take into account that it can happen, but it does not mean that we have to decide what to do, to many of this would be the end and many would sell, which is a very bad decision, the correct thing in these cases is to take advantage of being able to buy in order to accumulate as much BTC as possible, because something that the BTC market has not taught us is that it will have a new ATH and very juicy, if people thought that this would happen, they would take advantage of buying at $8k because it would simply be a bargain.
