As June 2025 approaches, traders are debating: Is the long-awaited altcoin season finally here? New data and shifting market dynamics suggest we might be on the cusp of a breakout moment reminiscent of the iconic rallies in 2017 and 2021. The buzz comes from Alphractal’s analysis of the Altcoin Season Index, a metric tracking the percentage of top 100 altcoins outperforming Bitcoin over the past 90 days. This index has recently signaled a shift away from Bitcoin dominance, suggesting a neutral to transitional phase—a stage historically associated with sharp altcoin rallies. June is often an inflection point in recent years for altcoin performance, coinciding with increased dominance. With Bitcoin currently consolidating, this dynamic creates the perfect environment for altcoins to attract investor attention.
