What is altseason and how to identify it? Altseason is characterized by: An increase in the share of altcoins: The share of Bitcoin in the total market capitalization (Bitcoin Dominance) falls below 50%, while altcoins such as Ethereum (ETH), Solana (SOL), XRP, Cardano (ADA), etc., grow faster. Metrics: Bitcoin Dominance: Decrease from 50-60% to 40-45% or lower. Altseason Index: CoinMarketCap and other platforms show an increase in altcoins by 50-200% over a short period (1-3 months). On-chain activity: An increase in transactions, active addresses, and TVL (total value locked) in DeFi protocols on platforms like Ethereum, Solana, Binance Smart Chain. Duration: Historically, altseason lasts from a few weeks to 3-6 months, after which a correction or return to Bitcoin dominance occurs. Status as of May 2025: Bitcoin Dominance is ~48-50%, which is below the peak of 60% in January 2025, but does not yet signal a full-blown altseason. Altcoins like SOL, XRP, and ADA have risen 20-50% since the beginning of the year, but meme coins (Dogecoin, Shiba Inu) have lost 6-37% due to a correction after the late 2024 boom. The Fear and Greed Index (~72) indicates optimism but not the extreme euphoria typical of the peak of altseason.
