Bitcoin and Ethereum are the two largest cryptocurrencies, but they were built for different goals. Bitcoin is digital money designed to be a store of value; Ethereum is a programmable platform for apps and smart contracts. This guide compares them.
What Bitcoin is
Bitcoin, launched in 2009, was the first cryptocurrency — a decentralized digital money that lets people transfer value without banks [1]. Its supply is capped at 21 million coins, and its network is secured by Proof of Work. Many people treat Bitcoin as a long-term store of value, sometimes called "digital gold" [2].
What Ethereum is
Ethereum, launched in 2015, is a programmable blockchain: beyond payments, it runs smart contracts and decentralized apps [1]. Its native coin, ether (ETH), pays for computation ("gas"). Ethereum moved to Proof of Stake in 2022 and, unlike Bitcoin, has no fixed maximum supply [2].

Bitcoin aims to be sound, decentralized money; Ethereum aims to be a platform for applications. They are complements as much as competitors, and many portfolios hold both. To keep learning the fundamentals, follow more from Bitbase Academy.
