A good strategy in the crypto world is:

1. Focus on a small number of targets and filter them logically. Many strategic opportunities arise, and we need to evaluate similar opportunities: a brand new narrative, a strong background, clear expectations, and a clear communication path.

2. Buy targets that have been consolidating to a certain extent and are almost impossible to drop further, whether they are former blue chips or small coins that have gone to zero. Their margin of safety is very high, similar to Graham's "cigarette butt" strategy.

Abandon everything in between and adhere to value investing: intrinsic value + margin of safety + long-term holding with periodic profit-taking.
