Cardano's smart contract progress, notably with Plutus V2 and upgrades like Alonzo and Vasil, enhances scalability and security, attracting developers to its energy-efficient platform. This has driven ADA’s value, with surges like the 139% rally post-Alonzo in 2021. However, declining wallet creation signals waning investor interest, potentially pressuring ADA’s price. Compared to Ethereum, Cardano offers lower fees and higher scalability via its eUTXO model, but Ethereum’s established DeFi and NFT ecosystems maintain its dominance. Cardano’s technical edge may challenge ETH long-term, yet adoption and market sentiment remain critical for ADA’s competitiveness.
