In the bull and bear cycles, I have summarized some simple principles that I hope will help beginners:
1. In a bull market, buy more as prices drop, provided you manage your position well, and set several price points for gradual buying.
2. In the later stages of a bull market, only sell long positions, and exit in batches.
3. Capital is king; do not borrow money and control risks.
4. Wealth is accumulated over time; don't always think about getting rich overnight, which is basically impossible. That pile of wealth won't just fall onto you.
5. Buy when no one is paying attention, sell when the crowd is bustling.
