#BTCvsETH

Bitcoin (BTC) and Ethereum (ETH) are the two largest cryptocurrencies, but they serve different purposes. BTC, created in 2009, is primarily **digital gold**—a store of value and hedge against inflation. Its supply is capped at 21 million, ensuring scarcity.

Ethereum, launched in 2015, is a **decentralized platform** for smart contracts and dApps (decentralized applications). ETH fuels transactions and operations on its blockchain. Unlike BTC, Ethereum focuses on **programmability**, enabling DeFi, NFTs, and more.

**Key Differences:**

- **Purpose:** BTC = digital money/store of value; ETH = smart contract platform.

- **Supply:** BTC is deflationary; ETH has no hard cap (but issuance is controlled).

- **Speed:** ETH processes transactions faster; BTC prioritizes security.

While BTC leads in adoption as "digital gold," ETH dominates in utility and innovation. Both are strong but serve different roles in crypto.
