#BTCvsETH Bitcoin (BTC) and Ethereum (ETH) are the two largest cryptocurrencies, yet serve distinct purposes. Bitcoin, often dubbed "digital gold," was created primarily as a decentralized peer-to-peer electronic cash system and a store of value, with a fixed supply of 21 million coins. Its focus is on secure, immutable transactions.

Ethereum, on the other hand, is a programmable blockchain platform. While it has its own native cryptocurrency, Ether (ETH), its core innovation lies in enabling "smart contracts" and decentralized applications (dApps). This makes Ethereum the foundation for vast ecosystems like DeFi, NFTs, and Web3, essentially acting as a global, open-source computer. Bitcoin prioritizes simplicity and security, while Ethereum emphasizes flexibility and utility.
