After three rounds of bull and bear markets, I have summarized some truths:

1. Buy more as the market falls during the bull market cycle, provided that you control your positions well.

2. In the late bull market, only sell long-term positions and do not buy.

3. Capital is king, control risks.

4. Moreover, wealth must be accumulated. It is basically impossible to get rich overnight. This pile of shit will not fall on you.

5. Buy when no one cares, and sell when everyone is talking.
