Bitcoin and Ethereum are the two most established cryptocurrencies in the world. If you're buying crypto for the first time, chances are you're wondering which one to start with — or whether you should own both. Here's the honest answer.
Before comparing them, it helps to understand what each one actually is. They are fundamentally different things built on similar technology.
Bitcoin was created in 2009 by an anonymous person (or group) known as Satoshi Nakamoto. It was designed to be digital money — a way to transfer value between people without a bank or government in the middle. That's it. Bitcoin does one thing, and it does it very well.
There will only ever be 21 million Bitcoin. This fixed supply is built into the code and cannot be changed. Because of this scarcity, many people compare Bitcoin to digital gold — a store of value that cannot be inflated away.
Ethereum was created in 2015 by Vitalik Buterin. It is a programmable blockchain — a platform on which developers can build applications (called "smart contracts" and "dApps"). Think of Bitcoin as a calculator and Ethereum as a smartphone. The smartphone can run apps; the calculator cannot.
ETH is the fuel that powers the Ethereum network. Every transaction and every application running on Ethereum requires ETH to pay for processing. This creates ongoing demand for ETH as the ecosystem grows.
Simple version: Bitcoin = digital gold / store of value. Ethereum = programmable blockchain / digital oil. Neither is "better" — they serve different purposes.
| Feature | Bitcoin (BTC) | Ethereum (ETH) |
|---|---|---|
| Created | 2009 | 2015 |
| Primary purpose | Digital money / store of value | Programmable blockchain platform |
| Supply | Fixed at 21 million | No hard cap (but partially deflationary) |
| Market cap (Apr 2026) | ~$1.4 trillion | ~$270 billion |
| Volatility | High | Higher |
| Staking / passive income | No | Yes (~4–5% APY) |
| Institutional adoption | Very high (ETFs, corporate treasuries) | Growing (ETFs, DeFi) |
| Regulation clarity (EU) | Very clear (MiCA: commodity) | Clear (MiCA: commodity) |
| Energy use | High (Proof of Work) | Very low (Proof of Stake since 2022) |
| Complexity for beginner | Simple to understand | More complex ecosystem |
Bitcoin makes sense as your first crypto purchase for several reasons. It is the easiest to understand — digital money with a fixed supply. It has the deepest liquidity, meaning you can buy or sell large amounts without moving the market. It has the most regulatory clarity globally. And it has 13+ years of track record, having survived multiple 80%+ crashes and recovered to new all-time highs each time.
Institutional adoption is also at an all-time high. US spot Bitcoin ETFs now hold over $100 billion in assets. Several major companies hold Bitcoin as a treasury asset. Central banks in multiple countries have discussed Bitcoin reserves. This level of institutional legitimacy did not exist five years ago.
Buy Bitcoin first if: You want simplicity, the best track record, and maximum regulatory clarity.
Ethereum's strongest argument is utility. It is not just a store of value — it is the infrastructure that powers most of decentralised finance (DeFi), NFTs, stablecoins, and an enormous range of applications. As long as these applications continue to grow, demand for ETH as their fuel grows with them.
The staking argument is also compelling. Since Ethereum switched to Proof of Stake in 2022, ETH holders can stake their coins and earn approximately 4–5% APY. This is passive income on a volatile asset — something Bitcoin cannot offer.
Buy Ethereum first if: You want exposure to the programmable blockchain ecosystem, passive staking income, and are comfortable with a somewhat steeper learning curve.
Many investors — including experienced ones — hold both Bitcoin and Ethereum. This makes sense for a simple reason: they serve different purposes and don't directly compete with each other.
A common beginner allocation is 70% Bitcoin / 30% Ethereum. This gives you:
The honest truth: For most beginners, starting with Bitcoin alone is perfectly reasonable. Once you're comfortable — you've been through at least one price correction, you understand how exchanges work — adding Ethereum makes a lot of sense. There's no rush.
For the absolute beginner, Bitcoin is the simpler and safer starting point. It's the most widely understood, the most liquid, and the most regulated. If you only ever own one cryptocurrency, Bitcoin is the right choice.
If you want to go further — and most people do — Ethereum is the natural second step. Together, BTC and ETH represent the two most established, most liquid, and most institutionally accepted cryptocurrencies in the world. Everything else carries significantly more risk.
Start simple. Bitcoin first. Ethereum when you're ready.
Both Bitcoin and Ethereum are available on all major exchanges. For European investors, we recommend:

In relative terms, yes — Bitcoin has a longer track record, larger market cap, and higher liquidity. Both are highly volatile compared to traditional assets. Neither is "safe" in the traditional sense, but Bitcoin is generally considered the lower-risk crypto option.
The "flippening" — Ethereum's market cap surpassing Bitcoin's — has been discussed for years. As of 2026, Bitcoin's market cap is approximately 5x Ethereum's. It remains possible in theory but has not happened, and many analysts consider Bitcoin's monetary premium too entrenched to be easily displaced.
Yes — absolutely. Bitcoin is divisible to 8 decimal places (the smallest unit is called a satoshi: 0.00000001 BTC). You can buy €10 or €50 worth of Bitcoin and own a fraction. The same applies to Ethereum. You don't need to buy a whole coin.
Altcoins like Solana, XRP, BNB, and others can offer higher returns but also carry significantly more risk. For beginners, we strongly recommend starting with Bitcoin and/or Ethereum before considering anything else. See our guide on investing in new cryptocurrencies for more context.
Yes — many investors buy both from the start. A simple 70/30 BTC/ETH split is a common approach. The advantage is immediate diversification across the two most established cryptos. The disadvantage is added complexity for a first-time buyer. Starting with Bitcoin only and adding ETH later is equally valid.
