A certain coin has reached the end of its trend; why not just short it directly? This question is actually quite typical, representing our common desire to buy low and sell high, which is a feel-good but harmful system.

1. The bottom and top are hypothetical; they are only predictions beforehand. Only after the fact do we know what happened. If we're wrong, do we have a contingency plan?

2. Suppose this place is indeed a high or low point as you predicted. There are many subsequent changes that can occur: consolidation, reversal, patterns... Once you enter the market, how do you respond to these changes?

3. Everyone wants to achieve profitable results, but how can this be done? The key is to control the process and protect your mindset. How to achieve this? Formulate a protection strategy; what to do if you're right? What to do if you're wrong?

4. Many times, giving up means giving up on what exactly? This is a question that needs to be answered by oneself.
