Been looking at the Altcoin Season Index lately and it's pretty telling what's happening in the market right now. The score is sitting at 19, which basically means only about 19 out of the top 100 altcoins have actually beaten Bitcoin's returns over the past 90 days. That's a strong signal we're still deep in a Bitcoin-dominated cycle.

For those not familiar with it, the altcoin season index measures exactly this - how many of the top altcoins are outperforming Bitcoin. When the index hits above 75, that's when you see real capital rotation into alts. But at 19? We're nowhere near that yet.

What's interesting is that this isn't just random price action - it reflects actual market structure. Bitcoin's got institutional money flowing in through ETFs, macro factors are driving it, while altcoins are getting hit harder by regulatory uncertainty. The index basically quantifies what traders have been feeling.

So yeah, if you're waiting for that altcoin season to kick off, the data says it's not happening anytime soon. Bitcoin's still the main event.
