Cardano's smart contract progress, notably with Plutus V2 and upcoming upgrades like Hydra, enhances its scalability and DeFi potential, potentially boosting ADA's value. Its energy-efficient proof-of-stake mechanism contrasts with Ethereum's higher-cost model, positioning Cardano as a strong competitor. However, Ethereum's established ecosystem and developer base (using Solidity) give it an edge, while Cardano's Haskell language may slow adoption. ADA’s value could rise with growing dApp usage, but competition from Ethereum’s upgrades (e.g., sharding) and rivals like Solana may challenge its market position. Long-term success depends on ecosystem growth and user adoption.
