#BTCvsETH Bitcoin (BTC) is primarily a digital gold, designed as a decentralized store of value and a peer-to-peer electronic cash system. It has a fixed supply of 21 million coins. Ethereum (ETH), on the other hand, is a programmable blockchain platform. While ETH is also a cryptocurrency, its main purpose is to power smart contracts and decentralized applications (dApps). This makes Ethereum a broader ecosystem for innovation, enabling everything from DeFi to NFTs, unlike Bitcoin's more focused use case as a digital currency.
