Why are you going to buy something so expensive and later sell it for lower price, it's either you don't know how Bitcoin price grow over the years or the person bought because other people bought and never really understand the importance of Bitcoin.
It's mostly due to a lack of knowledge, which causes fear and panic among investors who believe they are going to lose their money if they don't sell right now because they haven't done any research, they don't know much about the past cycles or the history of Bitcoin, they don't know anything about the bear markets and bull runs, all they know is that they can make money if they invest in Bitcoin because someone told them this or they might have read it somewhere, and they went ahead and invested, but as soon as they see the price dropping and their portfolio losing value, panic begins.
This is why it's not advisable for people to make investments when they are not really sure in what they are making their investments in and how it generally works. If I have some money that I want to invest, I will make sure that I find something which I can trust, and to know whether you can trust something or not, you have to do some research about it, gain some knowledge, at least basic knowledge, and then you decide whether you should go ahead and make the investment or not. If you do it without any research, you will end up panic-selling your assets when you see a temporary dip.
