Why does someone always make money with every rise and fall, but it's not you? The simplest reason: when everyone is not optimistic, you don't dare to buy; when everyone is optimistic, you can't bear to sell. That's why you lose. No one can buy at the lowest every time, and no one can sell at the highest every time. Even if it's Elon Musk or Donald Trump, and they handle it, it's the same. What you really need to learn is: when no one is paying attention, build your position gradually; when everyone is excited, be willing to sell. Don't aim for the bottom, don't gamble on the top. Know how to buy, and also know how to sell.
