Been watching the altcoin season index lately and it's sitting at 19—basically screaming that Bitcoin is having its moment right now. For context, this metric tracks how many of the top 100 altcoins actually beat Bitcoin's returns over the last 90 days, and when you're only seeing 19 out of 100 doing better, that tells you everything about where capital is flowing.

What's interesting is how this ties into the bigger cycle. We've seen this pattern before—Bitcoin dominance spikes, institutions pile in through ETFs and spot products, and the altcoin season gets delayed. Right now with Bitcoin's market share sitting strong and macro factors driving most of the action, retail money that would normally chase moonshots is sitting on the sidelines or rotating into Bitcoin itself.

The altcoin season index being this low doesn't mean alts are dead, but it's a clear signal that selective, research-backed positions make more sense than broad bets. The narrative is still Bitcoin-centric, and until we see that index push closer to 50 or higher, the structure favors conviction in the leading asset. Worth keeping tabs on when sentiment might shift, but for now the data is pretty unambiguous.
