No, trading isn't a dangerous profession. Don't see it that way. The only way someone could become rich today from trading and then poor tomorrow from it is if they became over confident from their winning and then jettison their trading strategy and plan. The market has a way of disciplining traders like that. It doesn't like traders getting over confident. Every trader should learn how to stay down and humble while winning. It helps take off pressure and impatience from them.
You are right, trading is not a dangerous activity, but it is a risky activity. The main risk is losing money, but the reward is gaining profit from it. If traders really want to be successful and get rich from it, then they must be disciplined and not force their will on the market too much. We cannot dictate the market, meaning the market can change at any time even if we have to go against the trend.
Traders who are greedy and overconfident will basically find it difficult to develop, they may have to go home empty-handed. If they are disciplined, then they will probably succeed, but still with the right approach and strategy.
