Everyone who conducts crypto trading must already have principles and know about profit or loss. My principle is that I will never sell when I see the results will lose, I better hold when the coins that I have bought are decreasing in price (holding is not afraid of losses) but part of the strategy. And I will sell when I increase, although I will definitely sell a little. Never be afraid to experience a loss, because loss is one of the risks in trading. But you must have a strategy.
Nah there are people who trade without having any strategy at all, and I have seen a lot of them. Some people just jump on trades and they don't even know what they are doing, yep that happens a lot here. One thing you have to know is that no one wants to be a loser, if there is anyone that wants to be a loser, which I have never seen before, then that' would be really weird. So the same thing you have in mind is what others have in mind as well, which is - profit. Whenever I invest, if I'm going to hodl then I make up my mind and take the risk, but I don't take stupid risks, I will first of all research about the coin I'm investing and know what experts thinks about it, whether it is going to grow in the nearest future or not. And I don't buy just any coin, I prefer to buy the top coins in the market.
