If you are at a loss because you bought at a price, why sell? If you are at a loss, it is better to wait for it to recover and then you decide what to do. People sell more when they are at a loss because of panic and comments that this will go to 0. If you sell, you will have less crypto and less money and you will want to buy when it is rising again and there you will see that the best thing was to wait for it to recover. This is normal for the market to go down. I say this from experience that I lost until I understood the market.
