Bitcoin's market dominance is approaching 60% in 2025 as altcoins lose influence, according to recent market trends. Analysts attribute this shift to Bitcoin's strong store-of-value narrative and institutional adoption, while many altcoins struggle with regulatory uncertainty and declining investor interest. The dominance level, last seen in 2021, signals a potential market consolidation around Bitcoin as the primary cryptocurrency asset. Experts note this trend could reshape the crypto landscape, with Bitcoin potentially absorbing capital from underperforming altcoin projects. The growing dominance coincides with Bitcoin's price stability compared to more volatile altcoins during recent market fluctuations.
