Insufficient understanding leads to difficulty in preserving wealth. Walk through the simulated trading, practice your mindset and courage, and avoid being slapped by reality in real operations.

1. If your capital is not very large, for example, within 200,000, it is enough to catch a major upward trend once a year. Never be fully invested all the time.

2. A person can never earn wealth beyond their understanding. First, use a simulated account to cultivate your true mindset and courage. A simulated account can fail infinitely, but a single failure in real operations may cost you everything, and you might even distance yourself from the market.

3. When encountering significant positive news, if you don’t sell on that day, remember to sell the next day at a high opening. The realization of good news often turns into bad news.

4. When facing major holidays, reduce positions or even go to cash a week in advance. Historically, the market tends to drop during holidays.

5. The strategy for medium to long-term trading is to keep enough cash on hand, sell at highs, buy back during declines, and rolling operations are the best strategy.

6. Short-term trading mainly looks at trading volume and chart patterns. Actively trade on patterns with significant fluctuations, and avoid inactive ones.

7. If the decline slows down, the rebound will also be slow; if the decline accelerates, the rebound will be quick.

8. Acknowledge your mistakes when buying incorrectly, cut losses in a timely manner, and preserving your principal is fundamental to survival in the market.

9. Always refer to the 15-minute K-line chart for short-term trading. You can find better buy and sell points using the KDJ indicator.

10. There are countless techniques and methods for trading cryptocurrencies; it's enough to master a few rather than being greedy.
