What is the difference between Bitcoin and Ethereum?
Quick Answer
Bitcoin is digital money — a simple, secure store of value and payment network with a fixed 21M supply. Ethereum is a programmable blockchain powering DeFi, NFTs, and smart contracts. They serve different purposes.
TL;DR
Bitcoin = digital gold, store of value. Ethereum = programmable platform for DeFi apps. Both are legitimate but different.
Key Takeaways
- 1Bitcoin has a hard cap of 21 million; Ethereum has no supply cap
- 2Bitcoin uses proof-of-work; Ethereum switched to proof-of-stake in 2022
- 3Bitcoin prioritizes security and simplicity; Ethereum prioritizes programmability
- 4DEXs like Hyperliquid are built on Ethereum-compatible technology
- 5Most investors hold both as different parts of a crypto portfolio
Full Explanation
Bitcoin and Ethereum are the two largest cryptocurrencies by market cap, but they were designed for fundamentally different purposes.
Bitcoin was created in 2009 as 'peer-to-peer electronic cash.' Over time it has become primarily valued as a store of value — 'digital gold.' Its protocol changes extremely rarely and conservatively. This deliberate simplicity is a feature, not a limitation: Bitcoin prioritizes security and predictability above all else.
Ethereum was launched in 2015 by Vitalik Buterin as a 'programmable blockchain.' It supports Turing-complete smart contracts — self-executing code that can represent financial agreements, NFT ownership, DAO governance, and thousands of DeFi applications. Protocols like Uniswap, Aave, and the technology underlying Hyperliquid's HyperEVM trace their heritage to Ethereum's architecture.
Key technical differences: Bitcoin's block time is ~10 minutes; Ethereum's is ~12 seconds. Bitcoin has a hard supply cap of 21 million; Ethereum has no cap but burns transaction fees to reduce circulating supply. Bitcoin's scripting language is intentionally limited; Ethereum is Turing-complete.
