#BTCvsETH Bitcoin (BTC) and Ethereum (ETH) are the two largest cryptocurrencies, but they serve different purposes. Bitcoin, launched in 2009, was designed as a decentralized digital currency and a store of value, often called "digital gold." Ethereum, introduced in 2015, is more than just a currency—it supports smart contracts and decentralized applications (dApps). While BTC has a fixed supply of 21 million coins, ETH has no hard cap but uses a burn mechanism to reduce inflation. Bitcoin is generally seen as more secure and stable, while Ethereum offers greater flexibility and innovation. Both play vital roles in the evolving blockchain ecosystem.
