Bitcoin (BTC) and Ethereum (ETH) are the two largest cryptocurrencies, each serving distinct purposes in the blockchain ecosystem. Bitcoin, launched in 2009, is primarily a decentralized digital currency designed to store value and facilitate peer-to-peer transactions. Its limited supply of 21 million coins and strong security make it a “digital gold” favored by investors seeking a hedge against inflation.
Ethereum, launched in 2015, extends blockchain utility beyond currency by enabling smart contracts and decentralized applications (dApps). It powers DeFi, NFTs, and a vast developer ecosystem, earning it the title “world computer.” While Bitcoin focuses on stability and scarcity, Ethereum emphasizes innovation and programmability.
BTC’s network is simpler and highly secure, while ETH’s upcoming upgrades (like proof-of-stake) aim for scalability and energy efficiency. Investors often hold both, with BTC as a store of value and ETH as a platform for future blockchain growth.
