1. The key to judging an expert is the length of time he/she keeps his/her position short: A true expert does not only make a profit when the market is rising, but more importantly, he/she knows that when the market is uncertain or the risk is high, he/she should choose to keep his/her position short. This patience and self-discipline are the core elements to success.

2. In a bear market, all purchases may fail: In a bear market, the overall market trend is downward, and any purchase behavior at this time is very likely to encounter a larger decline. Therefore, it is wise to maintain a cautious attitude and minimize or even avoid transactions before the market stabilizes or the bull market arrives.

3. In a bull market, all sales may be mistakes: In a bull market, prices continue to rise, and selling too early may miss out on more lucrative returns. Hold on, follow the trend, and consider selling when the market trend changes significantly.

4. The essence of investment is to buy low and sell high: It sounds very simple, but it is difficult to implement in practice. The key point is to have enough patience, wait for the right time to enter and exit the market, and not be swayed by short-term market fluctuations.

5. It is the main funds that determine the direction of the market: the main direction of the market is driven by large-scale funds. Understanding the dynamics of the main funds can help us follow the trend and avoid falling into the dilemma of going against the trend.

6. Both technical and fundamental analysis are no match for the general trend: Whether it is technical analysis or fundamental analysis, it seems insignificant in the face of the overall trend of the market. Going with the general trend is the key to achieving long-term profits.

7. Negative news at the top indicates the bottom, and you should sell decisively: When the market is at a high level, negative news often means that the market is about to reverse, which is an excellent signal to exit.

8. The negative news at the bottom actually means the bottom has been reached, so you need to buy boldly: At the bottom of the market, negative news usually reflects the extreme panic in the market, and this is precisely the best time to buy.

9. It is enough to be rich once in your life, and you must keep the wealth you have gained: do not be greedy, know how to take profits at the right time, and firmly guard the money you have earned. This is the key to achieving long-term success.

10. Bitcoin must be allocated, otherwise you may not make money in the bull market: As the leader of the cryptocurrency market, Bitcoin is often one of the currencies with the most impressive gains in the bull market. Reasonable allocation of Bitcoin can help us achieve stable returns in the bull market.

These valuable advices are the crystallization of wisdom from many years of practical experience, and are worthy of our careful consideration and strict compliance. I hope these suggestions can help everyone avoid detours in the market and move steadily towards success.
