The latest data from CoinMarketCap’s Altcoin Season Index indicates that the crypto market remains firmly in “Bitcoin Season,” with the index sitting at just 24 out of 100 — well below the threshold that would signal an altcoin-led cycle.
This means Bitcoin has outperformed most alternative cryptocurrencies over the past 90 days.
The contrast with late 2024 is stark: the index peaked at 87 in December, reflecting a strong altcoin trend, but dropped to a yearly low of 12 by late April 2025. Despite this, a few standout altcoins have managed to eclipse Bitcoin’s 30.1% gains over the same period.
Among the top performers are speculative newcomers like SYRUP (up 385%), PENGU (252%), and HYPE (228%), all of which have fueled talk of an approaching altcoin season. Others such as WIF, AAVE, BCH, ETH, and PEPE have also posted strong gains, outpacing BTC.
Still, the broader market sentiment remains cautious. The continued dominance of Bitcoin suggests capital is consolidating around the most established assets, and enthusiasm for altcoins has yet to hit critical mass. For now, the altcoin rally appears limited to select names, rather than reflecting a full market rotation.
