As of early June 2025, the cryptocurrency market is not currently experiencing an altcoin season. According to the Altcoin Season Index, only 25% of the top 100 altcoins have outperformed Bitcoin over the past 90 days, indicating that we are still in a Bitcoin-dominated phase .
However, analysts suggest that an altcoin season may be on the horizon. Historically, altcoin seasons tend to follow significant Bitcoin rallies, as investors seek higher returns in alternative cryptocurrencies. With Bitcoin's dominance currently at 63.9%, a potential decrease in this dominance could signal the beginning of an altcoin season .
Some experts predict that the latter half of 2025 could usher in an altcoin season, especially if market conditions shift favorably. Factors such as increased institutional interest in altcoins, regulatory clarity, and technological advancements could contribute to this shift .
In summary, while we are not currently in an altcoin season, market indicators suggest that one could emerge later in 2025, contingent on various economic and market factors.
