Bitcoin $BTC e Ethereum $ETH are the two largest cryptocurrencies, but with distinct purposes. BTC is seen as "digital gold", focusing on store of value and secure transactions. On the other hand, ETH is a platform for smart contracts and decentralized applications (DApps), with its programmable blockchain. While Bitcoin prioritizes security and scarcity (21 million units), Ethereum seeks innovation, transitioning to the proof-of-stake (PoS) model with ETH 2.0, aiming for scalability and energy efficiency. BTC dominates in market value and adoption as an asset, but ETH leads in utility and the DeFi ecosystem. Both have volatility, but ETH tends to fluctuate more due to its use in complex projects. Choosing between them depends on the goal: store of value (BTC) or innovation ecosystem (ETH).#BTCvsETH
