Altcoins have spent a good part of 2025 playing catch-up, often trailing both Bitcoin (BTC) and major stablecoins. With Bitcoin’s dominance recently surging to 64%, it’s certainly raised some concerns across the broader crypto market. Now, however, new analysis points to a shift developing. Data from Alphractal indicates that recent patterns in market indicators point towards a possible turning point.

Altcoin Dominance, excluding stablecoins, has consistently found solid support at around 25%. This level has acted as a floor during times when Bitcoin dominates market sentiment. Whenever this metric dipped to the 24%–25.3% range in the past, altcoins soon rallied across several weeks. These rebounds suggest that support in this range may be a key reversal point. Significantly, altcoin rallies that followed have tended to come swiftly and with high volume. While there is no certainty, this pattern carries historical weight.

This figure typically holds around the 18% mark. Interestingly, Ethereum plays a critical role in supporting the overall altcoin market. Whenever this narrower dominance dips under 18%, Bitcoin’s market share has historically declined. Altcoins have stepped up to claim more space in such moments. Moreover, the current landscape features far more altcoins than in past cycles. Despite the growing competition, this metric continues to show consistency.
