Just checked the Altcoin Season Index and it's sitting at 25 right now, which basically confirms what everyone's been noticing - Bitcoin's absolutely dominating the market while most altcoins are struggling to keep up. For context, the index only declares an actual altcoin season when 75% of the top 100 coins outperform Bitcoin over a 90-day period. We're nowhere near that threshold at the moment.

What's interesting is how CoinMarketCap measures this. They look at the top 100 cryptocurrencies but exclude stablecoins and wrapped tokens, so you're really seeing genuine price movement rather than noise. The methodology is pretty solid for tracking where capital is actually flowing.

Historically, these low Altcoin Season Index readings aren't necessarily bad news. Looking back at 2020-2021, Bitcoin dominated for months before capital rotated hard into altcoins. So this could actually be a consolidation phase where stronger projects build their base while weaker ones get filtered out.

The real question is what triggers the shift. Usually it's Bitcoin hitting a major price level and stabilizing, then fresh money starts chasing higher returns in altcoins. We're probably still early in that cycle. If you're thinking about positioning, this might be the time to identify which altcoins have solid fundamentals and real development activity, because when sentiment changes, rotation can happen fast.
