I think a lot of people are afraid when the market goes down, even in a matter of hours the price can change dramatically, this is just the same when you want to sleep and buy a few coins then when you wake up you are surprised to see prices change drastically.
I myself was very afraid if I was holding a coin then left it without regard to the price.
why should you be afraid? when you buy an asset you have calculated the time and price at which you will sell it. because it's also part of the research that you do. if you buy with origin, you have to be careful.
