1. There are many opportunities in the market, so in your upcoming trading career, you will miss many selling opportunities. Missing the top is common.

2. Even if you don't sell at the top, it's very likely you won't achieve ten times your investment. Even if you sell while the price is rising, getting three times your investment would be a good outcome; think about it, you actually haven't lost that much.

3. 90% of the coins you miss selling will eventually drop; are you sure you can sell at the highest point?

4. What's wrong with missing the top? You just didn't maximize your profits. Those who are fully invested in the bull market, do they regret not using high leverage at the bottom?

5. None of us are perfect; we will always make mistakes. If someone could do everything "absolutely correctly", theoretically, that person could control the world within a week.
