The day before yesterday, I bought Brevis at a low price, and the next day I took advantage of the rebound to sell. On paper, I made a profit. However, upon reviewing my trading decision afterward, I discovered a very painful problem.

To put it simply, the reason I bought Brevis had almost no technical content. The project's fundamentals, founder background, core competitiveness, and ecosystem data—these are the factors that determine a project's long-term value, and I didn't seriously look into any of them. The reason I entered the market was very pure: I saw the market was rising, followed the trend to buy in, and then aimed for a short-term profit margin.

Thinking this way, although I made money on this trade, the issues it exposed are worth being cautious about. Making a profit itself masked the recklessness of my decision-making, leading to survivor bias. Even more dangerous is that this trading pattern, which relies purely on emotions and charts without fundamental support, can easily lead to a crash when encountering the next project.

In the long run, investors who can go far in the crypto space are never gamblers but those who truly understand project logic and have a clear trading system. This small profit is actually a reminder—to seriously review my trading methodology.
