What is Bitcoin?

Bitcoin is the first cryptocurrency, created in 2009 by the pseudonymous Satoshi Nakamoto, and the largest by market capitalization (live ranking on CoinGecko). It introduced the blockchain and is used mainly as a store of value and a peer-to-peer payment network. Bitcoin uses Proof of Work consensus and has a fixed supply cap of 21 million coins.

What is Ethereum?

Ethereum is an open-source blockchain with smart contract support, launched in 2015 by Vitalik Buterin and co-founders. It is the base layer for most of DeFi and NFTs. Since The Merge in September 2022, Ethereum runs on Proof of Stake. It has no fixed supply cap, but EIP-1559 burns part of every transaction fee.

Key Differences

Bitcoin is designed as a decentralized store of value and payment network. Ethereum is a programmable platform for smart contracts, DeFi and dApps.

Bitcoin uses energy-intensive Proof of Work mining. Ethereum moved to Proof of Stake in September 2022, cutting its energy use by about 99.95% according to ethereum.org.

Bitcoin has a fixed supply of 21 million coins. Ethereum has no hard cap but burns part of every transaction fee, so its supply can shrink when the network is busy.

Ethereum confirms blocks about every 12 seconds, against roughly 10 minutes for Bitcoin.

Bitcoin's scripting language is deliberately limited for security. Ethereum's EVM runs general-purpose smart contracts, which enables complex applications.

Which Should You Choose?

Bitcoin and Ethereum serve different purposes and are often held together rather than as competitors. Bitcoin is mainly held as a scarce store of value: fixed supply and the longest track record in crypto. Ethereum is the settlement layer for most of DeFi and Web3, offering programmability that Bitcoin deliberately avoids. Many investors hold both as part of a diversified crypto portfolio.

Frequently Asked Questions

Is Bitcoin better than Ethereum?
Neither is objectively better; they serve different purposes. Bitcoin is primarily a store of value and digital gold, while Ethereum is a platform for decentralized applications and smart contracts. The better choice depends on whether you value scarcity and simplicity (Bitcoin) or programmability and ecosystem breadth (Ethereum).
Can Ethereum overtake Bitcoin in market cap?
This scenario, known as "the flippening," has been debated for years. Ethereum has a much larger ecosystem of dApps and DeFi protocols, but Bitcoin has kept a clear lead in market capitalization and is widely viewed as the main crypto store of value. As of September 2026, Bitcoin holds the number one position by market cap; check CoinGecko for the live ranking.
Why did Ethereum switch to Proof of Stake?
Ethereum moved to Proof of Stake with "The Merge" in September 2022 to cut energy consumption by about 99.95%, let ETH holders secure the network by staking, and prepare the ground for later scaling upgrades such as data blobs (EIP-4844) and danksharding.
Which has lower transaction fees, BTC or ETH?
Both networks have variable fees that depend on congestion. On-chain, fees on either chain can range from well under a dollar in quiet periods to tens of dollars at peak demand. Ethereum Layer 2 networks such as Arbitrum and Base process transactions for a few cents or less, while Bitcoin has the Lightning Network for cheap off-chain payments.
Should I invest in Bitcoin or Ethereum?
This is not financial advice. Many investors hold both because they play different roles. Bitcoin is often viewed as a macro asset similar to digital gold, while Ethereum offers exposure to the growth of DeFi, NFTs and Web3. Consider your risk tolerance and investment goals, and do your own research before investing.
