Rich kids lost 5 million, that's called "paying tuition." Family members pat their heads: It's okay, buy a lesson, accumulate some experience. This also became his future bragging material about "continuous entrepreneurship." You lost 500,000, that's called "sin." The parents' retirement money is gone, the whole family's house is gone, even if you only lost this one time, the entire family can't turn things around for ten years. This is the most desperate gap: tolerance for error. Don't listen to those big shots brag about "wolf spirit" or "daring to gamble." He's playing a game, with countless lives to restart; you're playing Russian roulette, with only one bullet in the gun, but you can't afford to lose. The so-called "bravery" is just because there's an unsteady safety net behind. Without that net, don't jump from that height easily.
