Wouldn't the whole crypto world be way more healthy by removing anyone have a thought about making a well-deserved profit by selling it higher to some else? How do you think if I tell you that your car or your house worth nothing because you shouldn't look at it as "an investment"? How would anyone buy a car/house if it doesn't have a price tag? State-provided cars and houses? Think about it for a second and you will see crypto is almost the same. Even if I don't consider my bay as an investment or invest in it, I'm sure won't easily give it away.
wouldn't apply such rules to the real-world will make it a better place, but you can't simply control everyone, you are not in their situation to judge.
sure some actions can't be justified even in crypto world, but it is a world of imperfection.
what you need is to make your own rules to deal with such reactions, trying to be step a head so you don't every time get hit by same wave. and accept it when you make the wrong decision, try to learn from it and make better investment next time.
