The Altcoin Season Index Is Still Below 50: What Needs to Happen Before Altseason Begins?

The altcoin season index suggests that the long-awaited altseason is yet to come.

On CoinMarketCap, the altcoin season index is currently at 41, meaning that less than a half of altcoins beat Bitcoin’s performance over the last 90 days. The website considers 75% to be the threshold for altseason.

However, the BlockchainCenter altcoin season index is at 57. The reason for this discrepancy is that BlockchainCenter takes 50 largest eligible coins into consideration as compared to CoinMarketCap’s 100. Its threshold for altseason is same: 75%.

Bitcoin trades around $63,700 and controls more than half of total crypto capitalization. Ethereum is around $1,625, while Solana’s price hovers near $78. The market is showing strength in some areas, but not near enough to suggest a broad-based rotation into altcoins.

What Is the Altcoin Season Index?

The altcoin season index is a metric that seeks to estimate how many of the major altcoins have outperformed Bitcoin.

CoinMarketCap assesses which of the top 100 eligible cryptocurrencies have beaten the price performance of Bitcoin over 90 days. Stablecoins, asset-backed, and wrapped tokens are excluded.
