Ethereum (ETH) and Cardano (ADA) are leading a significant capital reallocation away from Bitcoin, highlighting a growing investor preference for altcoins with advanced functionalities. Ethereum's move to proof-of-stake and Cardano's Alonzo upgrade have increased their attractiveness, especially in decentralized finance (DeFi) and decentralized applications (DApp) sectors. This trend indicates a maturing cryptocurrency market where utility and technological innovation are becoming more valued than traditional store-of-value assets like Bitcoin.
