Whether a person makes money from trading can be seen in many aspects; in the end, trading is really just a projection of one's personality. Here are a few typical examples.

Those who believe whatever others say and have no independent thinking are the most basic newbies; they keep buying and keep losing, ending up confused about their losses, and eventually quit saying, “This game is too hard to play.”

People who are 100% certain about everything and leave no room for doubt, even getting annoyed at opposing views, will sooner or later get trapped in a single asset. When that happens, they’ll still insist it’s the market’s fault and repeat the same mistakes next time. These are the favorite targets of market manipulators.

Those with stubborn personalities who never turn back after hitting a wall, always solving problems with one lie after another, ultimately end up trapping themselves. This is typical of people who keep averaging down when their positions go underwater—the kind of person for whom “cutting losses” is even more painful than anything else.
