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.
Those who are just taking the first steps in the crypto currency are afraid of this, the rest are already accustomed to falling prices and they know that the price can easily rise to the previous level in a couple of days
