A brother added me on WeChat on Friday, saying that RFC had a maximum profit of 2 million, but now it's retraced by half. He called himself an idiot, but I know what he's regretting. Actually, there's no need for that. When it was 2 million, you might have thought it could be 4 million tomorrow. Everyone has greed, it's normal. You need to have your own trading plan, like doubling your principal or taking out half when it increases tenfold. Having your own trading plan is good; how much you gain or lose is a matter of luck. During the conversation, he also told me he has a mortgage and wants to wait for a rebound to cash out and pay off the mortgage in one go. I told him if he has this idea, then don't hold on. Half an hour later, he messaged me saying he cashed out completely. A mortgage is like a big mountain; when you have the opportunity, don't take it lightly. When there's no opportunity, there's no regret medicine. Today, RFC dropped like crap. Maybe in a parallel world, RFC doubled again compared to Friday, but so what? The casino isn't afraid of you winning, it's afraid of you not gambling. Properly cashing out is always the right choice.
