I do not quite agree with you, because sometimes it would be right to sell at a lower price in order to save at least something
the opinions of different people are best done. selling at low prices may be safe, even if it's lost but loses a bit and not loses everything. maybe it's better to hold it back, because it hopes prices can rise again. all choices are good but sometimes circumstances that make it not good. The lessons in your life might make provisions in the future so do what you think is good because someone can only give advice or examples.
