Sharing an interesting case from personal experience. I invested 200k in this coin, Laozi. At that time, the operations team of a major exchange was highly promoting this project in the community, even saying they were researching related cultural concepts internally. The overall atmosphere was very lively. As an early trader testing the waters, I didn't think too much and followed the trend, jumping in.

Where was the problem? When the price went up, I directly sold all 700k holdings. It looked like I made a good profit, but it became a psychological burden later on.

I later summarized a few lessons: **Buying low itself is not a problem, but never sell everything at once**. A smarter approach is to set a clear target price, sell in batches, and keep some chips to hold on. This way, you won't fall into the whirlpool of "sold everything but the coin is still rising" frustration.

The biggest test in trading is not market judgment, but managing greed. That feeling of "I could still earn more" is often the first step to breaking your plan.
