Bitcoin (BTC) and Ethereum (ETH) are two of the most well-known cryptocurrencies.
Bitcoin, launched in 2009 by the pseudonymous Satoshi Nakamoto, is primarily seen as a store of value and a decentralized digital currency. It's often referred to as "digital gold."
Ethereum, launched in 2015 by Vitalik Buterin and others, is more than just a cryptocurrency. It's a decentralized platform that allows developers to build and deploy smart contracts and decentralized applications (dApps). Ethereum introduced the concept of "smart contracts," which are self-executing contracts with the terms of the agreement directly written into code.
Both have different purposes in the crypto space—Bitcoin as a digital currency and store of value, and Ethereum as a platform for decentralized applications and smart contracts.
