Why do people who actually make money usually only share their opinions frequently in small inner circle groups, but stay silent in larger groups? In groups full of pros, if someone shares a judgment and everyone acts on it—if they lose money, no one complains; if they make money, they’ll even send red envelopes to celebrate. But in some lower-quality retail investor groups, when they make money, they’re nowhere to be seen; when they lose money, they start cursing everything and blaming everyone. One is positive feedback, the other is negative feedback. If you’re someone who makes money, where would you choose to speak?
