According to Michaël van de Poppe (@CryptoMichNL), the Altcoin season indicator has reached its lowest level in two years as of June 2025. Historical data shows similar lows occurred in June or July each year from 2019 to 2024, suggesting a seasonal pattern. This cyclical behavior is critical for traders as it may signal upcoming shifts in altcoin (ALT) market momentum. Monitoring this indicator can help anticipate potential rotations from Bitcoin (BTC) dominance to altcoin rallies, providing actionable insight for portfolio allocation. Source: Twitter/@CryptoMichNL.
