Having worked in the crypto market for many years, I have seen too many people lose everything in the market. Instead of blindly chasing trends, it's better to clarify your trading logic.

Based on years of practical experience, these rules are worth remembering:

1. For a principal of less than 100,000, never fully leverage your position. Controlling your position size means leaving room for maneuver, and one major upward wave can change the game.

2. Armchair strategizing can be deadly. Don't rush into real trading before developing a stable mindset on a demo account.

3. The moment good news is announced is often a signal to sell. If the market opens high but doesn't rise, exit decisively.

4. Declines around holidays are almost predictable. Reduce your holdings in advance to at least ensure the safety of your principal.

5. Mid- to long-term trading requires sufficient cash reserves. Sell at highs, buy back at lows, and cycle through these to make profits.

6. For short-term trading, focus on active popular coins (like XRP with good liquidity). Ignoring less-known coins wastes time and opportunity costs.

7. The rebound after a sharp decline is more powerful; rebounds during a downtrend are often traps. This point is critical.

8. Stop-loss is not about admitting defeat; it's the bottom line for survival. As long as you have bullets, new opportunities will appear at any time.

9. The key to short-term trading is to monitor the 5-minute K-line combined with the KDJ indicator; buy and sell points become very clear.

10. Trading skills are not about fancy tricks. Master one or two methods thoroughly; familiarity and proficiency are more reliable than trying to know everything and losing.

The crypto market is like this — either watch others eat meat with your eyes wide open, or find a reliable logical system and stick to it. Those who survive long in this market are never relying on luck.
