The Altcoin Season Index and CZ's Observations
• Alt Season Index, as highlighted by Binance founder CZ on July 23, 2025, shows a bullish signal for an imminent altcoin season.
• CZ pointed out on X (formerly Twitter) that CoinMarketCap's Altcoin Season Index was ticking upwards, reaching 54 out of 100 at that time, which indicates altcoins beginning to outperform Bitcoin after a period dominated by Bitcoin.
• This index measures the performance of the top 100 altcoins compared to Bitcoin over the past 90 days.
Defining Altseason and Index Methodology
• A score above 50 signals the start of altseason, where altcoins gain momentum and market participation increases, often driven by shifts such as Bitcoin dominance dropping below 60%.
• The Altcoin Season Index methodology states that if at least 75% of the top 100 altcoins outperform Bitcoin in the last 90 days, the market is in altseason.
Market Implications and Investor Sentiment
• CZ’s tweet suggested market participants might soon enter a period of "FOMO season," where altcoins experience significant price appreciation as the market rotates capital from Bitcoin to altcoins.
• Recent altcoins like Ethereum and Solana have shown strong performances and derivatives activity, supporting this bullish outlook.
• Thus, based on the Alt Szn Index movement and CZ’s commentary in July 2025, the market was signaling a potential altcoin season run shortly thereafter.
• Investors and traders were encouraged to watch for increasing altcoin momentum as Bitcoin dominance declined and liquidity flowed into altcoins.
• This summary provides an insight into the altcoin season forecast and its implications for crypto markets as of mid-2025.
