Altcoins are booming again: Is a true altseason here, or is this all a mirage?

While social media is calling for liftoff, some are throwing cold water on the altseason narrative.

According to a post by Marktquant, the 200-day breadth index sits at a tepid 15 — well below the 30 level typically seen before major altcoin expansions.

Meanwhile, the 50-day breadth is rising, but still hasn’t broken decisively above 50, a key marker for short-to-midterm momentum.

Historically, altseasons have been backed by both indicators moving in tandem; signaling participation across a wide range of assets. Right now, that’s just not the case.

This isn’t a broad-based rally; it’s a pocketed, selective environment where only a handful of technically or fundamentally strong alts are outperforming. For now, the trend favors patience over parabolic bets.
