Here are 15 core rules for survival in the cryptocurrency world:

1. Capital comes first! Protecting your capital is key to survival; it cannot be emphasized enough. Many people focus solely on making money and overlook risks, ultimately being taught a lesson by the market.

2. Reject greed and aim for steady profits. If you are not greedy, making money is not difficult; stable and moderate profits are more reliable, and slow is fast.

3. Diversify your investments, keep enough positions, and follow the trend. Never go all in; otherwise, you'll have no way out when the market reverses.

4. Avoid heavy positions, do not buy coins in a downtrend, avoid frequent trades, and do not chase high and sell low. These are all good habits for leaving yourself an exit.

5. Slow down your buying; accumulate gradually during sideways movement; be decisive when selling, and take action immediately when you reach your target.

6. Money can always be made, but it can also be lost. Don’t try to capture all profits; the market can counterattack at any moment.

7. Opportunities are frequent, but if the fundamentals deteriorate, you must stop losses immediately, or you could lose everything overnight.

8. For long-term views, look at weekly charts; for ultra-long-term views, look at monthly charts. When a trend reverses or enters a downtrend, it's best to take profits; what you've secured is the most stable.

9. The market will always reverse extremes; don't fantasize that trends won’t reverse.

10. Don’t trade without opportunity. Missing out is normal; just seize part of the opportunities without needing to capture all.

11. Waiting for opportunities is better than looking for them; patience is the core weapon of a trader.

12. Once you reach your target, stop. Energy is limited, and there’s no need to pursue continuous profits.

13. Stopping losses is a responsibility; profits are a gift from the market, which owes nothing to anyone.

14. Profits come from waiting rather than frequent trading; don’t think about high-frequency trading.

15. Desire destroys mindset, while execution is life-saving. Operate strictly according to your strategy, don’t be swayed by emotions, and achieve unity of knowledge and action.
