It doesnt really have any sense if we do really talk about selling on loss or on a bear market but instead it would really be that sensible that you would rather be buying instead.Yes its not
really that simple because emotions will really be your main enemy on here which you cant really be that too confident on making such action.
Best time to buy is on when everyone is on fear, its really a very common market sentiment or sayings but applying it on such situation is never been easy.
Just act according into your risk taking because we do have different levels when it comes to this.
Selling at a loss is still a strategy so it can make sense for someone who get an advantage of doing it but maybe not for you because you haven't tried it. Those who use sell at a loss start will always buy back again when the price dips but there are people who simply sell at a loss because they badly need a money especially now that we are experiencing a problem outside but for those who are unaffected with that problem then they can use their money instead for buying more coins. It's possible to be over confident here.
It's not wrong as long as you know that you pick up the right coins. It's only not good if you are a person who gets easily disappointed when the coins you pick didn't move according to your expectations.
