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 not ethereum prices declined
Previously we don't have any idea about the cryptocurrency market situation where many people failed to sell them at a higher price. During the last bull run, there are only very few fiat currencies, which nobody has any idea about converting for ETH to USDT. So it is always good to hold them in long term.
