Many times I came across the fact that some people hold coins that should have been sold. At one time they were quite successful, but then they reached their price peak and then their price began to decline. It is very important to be able to take profit on time.
that also happened to me, when ethereum prices were very high, and I did not immediately sell them when ethereum prices began to show a decline, because at that time I was sure that ethereum prices would return to normal but in fact no, ethereum would go down
