The so-called bull market will ultimately harvest the wealth of many people.

This is the law of nature.
It's too difficult to overcome human weaknesses. Saving others is hard, and speaking too much leads to misunderstanding and resentment.
What Duan Yongping called "duty" is actually managing yourself. I think regardless of bull or bear markets, frequently remembering duty is sufficient. These two characters are truly minimalist.
Investment duty requires three things:
1. Earn money from enterprise cash flows; in crypto, earn from super-tier companies that survive bull and bear cycles.
2. Earn money within your circle of competence; in crypto, only Bitcoin qualifies.
3. Stay away from the market; in crypto, stay away from FOMO.
Besides fulfilling investment duty, I think there are two more internal duties: "don't take yourself too seriously," don't obsess over face, and don't be jealous of others.
Investing is an individual competition. Achieve these requirements and you'll have tranquility and freedom. Fail to achieve them and you'll suffer, feel troubled, and be plagued by noise.
