#BTCvsETH Bitcoin (BTC) and Ethereum (ETH) are leading cryptocurrencies with distinct roles. BTC, launched in 2009, is a decentralized digital currency focused on store-of-value and peer-to-peer transactions, using proof-of-work for security. Its fixed supply of 21 million coins drives scarcity. ETH, launched in 2015, powers the Ethereum blockchain, enabling smart contracts and decentralized applications (dApps). ETH uses proof-of-stake, improving energy efficiency. BTC’s market cap dominates, but ETH’s versatility fuels DeFi and NFT growth. BTC is seen as "digital gold," while ETH is a platform for innovation. Price volatility affects both, with BTC often more stable. Investors weigh BTC’s simplicity against ETH’s broader utility for portfolio diversification.
