The altcoin season is a time period during which 75% of the altcoins ranked in the top 50 cryptos by market capitalization outperform Bitcoin in a 90-day timeframe. Traders await the altcoin season every market cycle to take profits on alternative tokens as capital rotates from Bitcoin to other cryptos.
The ongoing market cycle has been different from the others as institutions back Bitcoin, Ethereum and top cryptocurrencies across various sectors of the industry, rather than rotating capital into altcoins. Meme coins, AI agent tokens and Ethereum Layer 2 chains have rallied in the last six months on different occasions, in a manner similar to the previous altcoin season.
The current market scenario with rising geopolitical tensions, mass market liquidations and Bitcoin price decline, could delay or potentially end the cyclical arrival of the altcoin season.
The altcoin season index, an indicator that measures on a scale of 0 to 100 whether it is altcoin season or not, reads 14. The value corresponds with a Bitcoin season where BTC gains are dominant for traders and Bitcoin outperforms altcoins ranked in the top 50.
When the indicator crosses 75, it is considered an altcoin season. The indicator shows that since mid-May, it has been Bitcoin season and the value is below 25.
