When a token surges dramatically but still has 10% of its total supply sitting around the sub-$5K zone, that's usually a red flag. Why? Because it means the project's upside potential might already be priced in. The sheer availability of coins at those lower price levels creates a massive supply wall—essentially, it becomes a ceiling for future growth. Holders who got in early will likely take profits, and new buyers face resistance. That's when you know the momentum's running on fumes. A healthy token typically tightens its lower-tier supply as it climbs. If it doesn't, it often signals the party's over.
