Just checked the latest altcoin season index data and it's sitting at 19—basically confirming what we've all been watching unfold. Bitcoin's completely dominating right now, with only about a fifth of the top altcoins actually beating it over the last 90 days. The metric's pretty straightforward: CoinMarketCap tracks whether 75% of the top 100 alts outperform Bitcoin, and when you're at 19, well, that tells you everything. Macro factors are clearly winning over individual project narratives at the moment. Institutional money flowing through spot ETFs keeps giving Bitcoin a steady bid that alts just can't match, and the regulatory uncertainty around altcoins isn't helping either. The altcoin season index historically spikes above 75 when capital starts rotating into higher-risk assets, but we're nowhere near that yet. For traders, this means Bitcoin season is still firmly in control—playing it safer, focusing on the big names, and waiting for that shift. Most cycles eventually rotate, but the timing remains uncertain. For now, the data's pretty clear on what's winning.
