According to The Block's data and insights report, Bitcoin's share of the crypto market has fallen from a peak of 62% to 55%, indicating the market is entering the early stages of a capital rotation from Bitcoin to altcoins. Ethereum (ETH) and Solana (SOL) are attracting renewed attention from both institutional and retail investors, while several digital asset treasuries are raising funds and purchasing assets through publicly traded entities, supporting the potential rise of altcoins. The report indicates that if the market continues to favor riskier assets, altcoins have further room for growth in the fourth quarter, but the key lies in whether genuine physical demand can be generated, rather than relying solely on short-term derivative-driven rallies.
