After watching many reviews of a8 and a9, I have summarized some rules:

1. Prepare enough trial and error costs; he invested in 10 projects, and the first 9 may have gone to zero, but the last one brought in a wave of a8.

2. Always maintain curiosity; after playing for so many years, this circle often rewards the first project, while the second may lead to losses.

3. Small victories rely on intelligence, large victories rely on virtue; stay away from short-term trading and contracts. A diamond hand is not about being smart enough, but about having a grand vision and ambition.

4. Opportunity: Every 3 to 5 years, there will be a significant opportunity in the cryptocurrency world; if you seize this opportunity, you can earn what you couldn't earn in the past 10 years.
