Just checked the altcoin season index and it's sitting at 19 right now. For those not familiar, this basically tracks whether the top 100 altcoins (minus stablecoins) are beating Bitcoin over a 90-day window. When 75% of them are outperforming BTC, we're in altcoin season. At 19, we're definitely not there yet.

What's interesting is how much this single number actually tells you about market structure. It's not just a random metric—it's showing that Bitcoin is just crushing everything else in relative performance. The institutional money flowing in through spot ETFs, macro economic factors, regulatory uncertainty around smaller projects... it all adds up to this one clear signal: Bitcoin season is still firmly in control.

Historically, we've seen altcoin season index readings spike above 75 during those crazy bull cycles where retail money chases the moonshots. But right now? Capital is being way more selective. Developers are feeling the pressure, trading volumes are concentrated in Bitcoin and major blue-chips, and the broader ecosystem outside of Bitcoin and Ethereum is moving slower. The real question is when this shifts. The altcoin season index will probably be our clearest indicator when it happens, but for now it's telling us to stay patient and watch the macro picture closely.
