The most fatal way to lose in the crypto world is not not knowing how to choose coins, but in one word: hold. As soon as the coin starts to fall, 99% of people’s first reaction is not to stop loss, but to self-hypnotize – "let's wait and see, I'll sell when it rebounds." As a result, they don't sell on the first day's rebound, and when it falls again the next day, they continue to wait, with the reasoning always being: "It's not at my psychological price yet." The market doesn't need to cut you off in one go; it only needs to grind slowly to drag your rationality, profits, and principal down with it. What really destroys people is not a single fall, but the repeated unwillingness to admit mistakes. It's tolerable to fall two points, but when it falls five points, they start to feel conflicted, and only when it falls thirty or forty points do they realize: the profits are gone, and the principal is locked up. This isn't a problem with the market, it's that the operational logic was wrong from the start. Mature traders always think about one thing before placing an order: what to do if they're wrong. Once the trend goes bad, they immediately exit, not arguing about right or wrong, just preserving their life. They allow for small losses, but never allow a single mistake to wipe out all their efforts. If you look at those who make money in the long run, their stop losses are brutal. Because they understand: if you don't stop loss, no matter how much you earn, it will all be given back in one pullback. Only those with unchanged logic, sufficient funds, and a long enough cycle can truly discuss "buying more as it falls"; while most people just can't bear to admit they were wrong. Trading is not about who predicts correctly, but about who can still stand after making mistakes. The market is always there, and opportunities won't be scarce; what you need to do is leave yourself a way out with every order. Don't mistake luck for strategy; if you want to last in this market, first learn to admit mistakes gracefully. Get the rhythm right, and the turnaround will come. Follow Wang, and don’t keep holding a losing position with your life.
