Trading in the secondary market tests not whether a person is smart, but rather tests a person's ability to summarize patterns, as well as personal character. As long as you observe more, practice more, and remember, keeping a long-term watch on the market, after experiencing a bull and bear cycle, you will naturally become an expert. Whether you can make big money in the market is entirely determined by your character.
This market is unfair, but for ordinary people, the secondary market is already a relatively fair market. If you trade BTC, ETH, or large-cap mainstream altcoins, at least you are standing on your own abilities to either lose money or make money.
Instead of relying on insider information or connections to engage in front-running, which is something that ordinary people generally will never encounter due to their lack of positional advantage throughout their lifetime.
