After 7 years of cryptocurrency trading, I've made over 30 million, and now I rely on it to support my family. This process has led me to realize six key insights, though brief, they are profound!

1. When trading cryptocurrencies, focus on the strong ones. If unsure, look at the 60-day moving average; buy or add when above it and withdraw when below. This method works most of the time.

2. If something suddenly rises over 50%, don't rush to chase it; it can easily lead to panic. It's better to enter at a lower position for stability, reducing risk, and potentially gaining more.

3. Before a big rise, there are always signals, such as small price fluctuations of 10% to 20%, but with low trading volume. At this time, slowly buy at low levels, and you will likely catch the upward momentum.

4. When a new market hotspot emerges, it will definitely be hot in the first few days. Seize this opportunity and follow the large investments for easy profits.

5. When a bear market arrives, you must restrain yourself; don't trade for at least six months. In a poor market, reduce your trades; knowing when to rest is a sign of a true expert.

6. Every week, take a moment to reflect, not to see if you made a profit, but to assess if your strategy is correct. If it's right, stick with it; if wrong, adjust. After a few months, your trading strategy will stabilize.

Remember, success does not fall from the sky; it is for those who are prepared.
