Bitcoin vs Ethereum: What Is the Difference? A Beginner's Guide
Bitcoin is a digital currency and store of value with a fixed maximum supply of 21 million coins. Ethereum is a programmable blockchain where developers build apps called smart contracts, and its coin, ether (ETH), pays for using the network. Bitcoin is simpler and more focused. Ethereum is broader and changes more often. Both are volatile, and you can lose money in either.
What is Bitcoin?
Bitcoin was created by a person or group using the name Satoshi Nakamoto. The idea was published in a nine-page paper in 2008, and the network started in 2009. Its goal is to let people send value to each other over the internet without a bank in the middle. You can read the Bitcoin whitepaper explained in plain English.
- The maximum supply is fixed at 21 million bitcoin.
- It uses proof of work: computers called miners compete to add new blocks, roughly one about every 10 minutes.
- New bitcoin issued to miners is cut in half about every four years, an event called the halving.
- Many people hold it as a long-term store of value, sometimes called digital gold. Others use it for payments.
What is Ethereum?
Ethereum was proposed by Vitalik Buterin in a whitepaper in 2013 and launched in 2015. It is a blockchain that can run programs called smart contracts. These are pieces of code that run automatically when conditions are met, so developers can build apps without a central company running them. Read the Ethereum whitepaper explained.
- Its coin, ether (ETH), pays the fees for using the network.
- It moved from proof of work to proof of stake in 2022, in an upgrade called the Merge. Holders can stake ETH to help secure the network.
- It does not have a fixed maximum supply like Bitcoin.
- It is used for decentralised finance (DeFi), stablecoins, digital collectibles and many other apps.

| Supply | Fixed at 21 million | No fixed maximum |
| How it is secured | Proof of work (miners) | Proof of stake (validators) |
| Programmability | Limited by design | Broad, a full programming language |
| Pace of change | Slow and cautious | Faster, with regular upgrades |
Which one should a beginner learn first?
Start with Bitcoin to understand the core ideas: blockchains, wallets, keys and scarcity. Then learn Ethereum to understand smart contracts, DeFi and stablecoins. You do not need to own either to learn how they work, and many people learn first with no money at risk.
How can you research them with AI?
Use AI as a thinking partner, then verify. Our prompt guide has 15 ready prompts: 15 ChatGPT prompts for crypto research. Here is one for this topic:
What are the risks?
- Price swings. Both can fall sharply in a short time.
- Custody. If you lose your keys or seed phrase, no one can recover your coins. Never share a seed phrase with anyone.
- Scams and impersonation. Many scams use the names of famous coins.
- Regulation and tax. Rules differ by country and change over time.
- Technology risk. Bugs, hacks and design changes can affect any network.
You can also get exposure through regulated funds. See Bitcoin ETFs and BlackRock's IBIT explained.
