Is It Altcoin Season? Use Our Altseason Index Checker

Altcoin Season is one of the most anticipated phases in the crypto market — when altcoins surge past Bitcoin in performance.

Our Cryptocurrency Altseason Index Checker helps you identify early signs of altseason by analyzing how many top 100 alts are outperforming BTC — based on the same logic used by CoinMarketCap's Altcoin Season Index.

What Does “Altseason” Mean?

Altseason occurs when 75% or more of the top 100 cryptocurrencies (excluding stablecoins and wrapped tokens) deliver better returns than Bitcoin over a sustained period — typically 90 days.

When this happens, capital rotates from BTC into alts like Ethereum, Solana, Cardano, and emerging projects — creating massive growth opportunities.

How This Tool Works

While a true real-time index requires advanced data pipelines, our checker uses the official CMC methodology:

  1. Tracks price change of each top 100 coin vs. BTC over 90 days
  2. Counts how many outperform BTC
  3. If ≥75 (75%), altseason is ON

Since manual tracking is time-consuming, we provide a simplified version where you can input current stats or view weekly updates.

Why Traders Watch for Altseason

  • Huge Gains: Many alts rise 5–10x during strong altseasons
  • Diversification: Reduces reliance on BTC-only exposure
  • Early Signal: Helps time entries before FOMO spikes

Note: Ethereum is considered an altcoin in this index — so ETH rallies count toward altseason.

Pro Insight: Combine this with Fear & Greed analysis. Altseason often begins when sentiment shifts from fear to greed after a BTC rally.
Note: This tool currently displays a static estimate based on recent data. We update it weekly. Full automation coming soon.
