Bitcoin (BTC) and Ethereum (ETH) are the two leading cryptocurrencies in the world. BTC is known as digital gold, created for secure, decentralized peer-to-peer transactions and as a store of value. ETH, on the other hand, powers the Ethereum network—a smart contract platform that enables decentralized applications (dApps), DeFi, and NFTs. While BTC focuses on being a sound money system, ETH drives innovation and utility across the blockchain ecosystem. Both are key pillars of the crypto market.
