In early 2025, Bitcoin's market dominance has surged to approximately 62%, a peak not observed since February 2021. This ascent is attributed to several factors, including institutional investments, favorable regulatory developments under President Donald Trump's administration, and the introduction of spot Bitcoin ETFs. Notably, while Bitcoin's dominance strengthens, altcoins have experienced significant declines, with Ethereum's market share dropping to 10.2% from 17% the previous year. Despite the current trend, some analysts anticipate a potential altcoin resurgence, contingent upon increased blockchain activity and clearer regulatory frameworks.
