Ethereum is the second-most-owned cryptocurrency in the world and the chain almost every interesting application in crypto runs on top of. Buying ETH is mechanically the same as buying Bitcoin: pick an exchange, fund it, place an order, move it off. The differences are what you can do with ETH after you own it, which makes the self-custody and wallet decisions worth more attention than they get in most beginner guides.
Everything below assumes you’ve read or will read the how to buy Bitcoin guide for the shared mechanics. This guide covers what’s different for ETH and where the decisions actually matter.
Why buy ETH rather than just Bitcoin
Ethereum does something Bitcoin does not. It runs a general-purpose computing layer that most of stablecoins, DeFi, NFTs, and real-world-asset tokenization settle on. Owning ETH is a bet that this computing layer remains the default home for onchain finance. That bet has been contested repeatedly (by Solana, by various L1 rivals, by the “modular” roadmap that moved activity to L2s) and ETH has underperformed BTC for most of the last three cycles as a result. The bull case in 2026 rests on two things: real-world asset tokenization is happening primarily on Ethereum and its L2s because settlement assurance matters for anything involving traditional finance, and spot ETH ETFs with staking are now live, which gives traditional investors a regulated way to earn ETH-denominated yield.
If you’re optimistic on the future of programmable settlement, own some ETH. If you’re purely long a digital store of value, Bitcoin is the cleaner vehicle. Most sensible portfolios hold both at different weights.
Where to buy Ethereum
The exchange shortlist is the same as for Bitcoin because ETH is supported on every major venue. What changes is staking. If you plan to stake, that becomes a criterion.
In the United States, Coinbase and Kraken both offer integrated ETH staking with fees around 25%, meaning the exchange keeps about a quarter of the staking yield. Fidelity Crypto does not currently offer staking. If staking isn’t a priority, Kraken’s lower trading fees (0.16% maker, 0.26% taker on the pro interface) make it the economic choice for any serious purchase. Coinbase remains the friendliest onboarding and the easiest place to set up automated recurring buys. Binance.US is still skippable.
In the United Kingdom, Kraken UK has the best combination of Faster Payments rails, FCA registration, low fees, and staking availability. Bitstamp is the slower but more conservative alternative. Coinbase UK works; the simple interface is again where the unnecessary fees live.
In the European Union, Bitvavo is the fastest path to ETH for EUR-denominated buyers, with SEPA Instant deposits and low fees. Kraken’s EU entity is the better option for larger purchases or anyone planning to stake or trade futures. Bitstamp remains the oldest and most conservative option on the continent.
MiCA is now the operative regulation across the EU and means unlicensed venues are being pushed out of the market. For ETH specifically, any MiCA-compliant exchange handles the basics competently; the differentiation is fees, staking, and whether you want your money at a larger or smaller operator.
Making the purchase
Open an account. Complete ID verification. Fund the account by bank transfer (ACH in the US, Faster Payments in the UK, SEPA in the EU) rather than by card, which costs 3-5% versus 0%. Move to the advanced trading interface on whichever exchange you picked. Place a market buy on the ETH/USD, ETH/GBP, or ETH/EUR pair.
Two minutes. Done.
The simple buy flows on Coinbase, Binance, and a handful of others charge you 1.5-2% for the privilege of not clicking a different tab. On a $5,000 ETH purchase, that’s $100 you could have kept. Use the advanced interface.
One ETH-specific consideration: if you’re buying to stake, most exchanges let you enable staking directly from the ETH balance page after the purchase settles. The yield will appear in your account over the following week. This is the easiest way to dip into staking before committing to a more sophisticated setup.
Moving ETH off the exchange
This is where Ethereum diverges meaningfully from Bitcoin, because once your ETH leaves the exchange, there’s a lot more you can do with it and a lot more ways to lose it.
For a first position staying in cold storage, the setup mirrors Bitcoin: mobile wallet below $1,000, hardware wallet above that. MetaMask is the default Ethereum browser extension and mobile wallet; it supports ETH plus every ERC-20 token and L2 network. Rabby is MetaMask with better transaction-risk warnings and is the better default in 2026. Both pair with a Ledger or Trezor for the keys-in-hardware setup that keeps the private key off your computer. Safe (formerly Gnosis Safe) is the multi-signature wallet most DAOs and serious treasuries use; overkill for a $5,000 position, essential for a $500,000 one.
Test withdrawals matter more on Ethereum than on Bitcoin because one mistyped character in a wallet address ends in a permanent loss and because more bad actors are dropping into Ethereum-using browser sessions than into Bitcoin-native apps. Send $20 of ETH from the exchange to your wallet, verify it arrives, and then move the rest.
Never sign a transaction you don’t understand. Rabby will flag most suspicious contract interactions; honor those warnings. MetaMask’s native warning surface is thinner, which is one reason to use Rabby.
Staking decisions
Stake if you understand what you’re signing up for. The yield is real (3-4% APR in ETH, denominated in ETH, not dollars) but it comes with mechanics you need to see clearly.
Exchange staking is the simplest: your ETH stays on the exchange, they stake it on your behalf, they take 25% of the yield as a fee, and you can unstake with a delay measured in days. You carry exchange custody risk the whole time. Kraken’s earn program and Coinbase’s staking feature both work this way.
Liquid staking via Lido or Rocket Pool issues you a tokenized claim on your staked ETH (stETH or rETH) that you can sell or use as collateral elsewhere. You keep self-custody, you avoid the exchange haircut on yield, and you take on the smart-contract risk of the staking protocol. The Lido protocol has been through multiple audits and has the most staked ETH of any entity, which is both an endorsement and a concentration risk worth thinking about.
Solo staking requires 32 ETH (roughly $100,000 at April 2026 prices) and a dedicated node. If you can afford it and you want to, it’s the most decentralization-positive option. If you can’t, don’t force it.
Taxes on staking rewards in most jurisdictions treat each reward as ordinary income at receipt and a cost-basis event for later sale. Track this properly from day one. Koinly and CoinLedger both handle staking rewards automatically from major exchanges.
Gas, L2s, and the part nobody explains
Ethereum mainnet gas costs real money. A basic ETH transfer might cost $1-2 at low congestion and $10-20 at peak. A DEX swap might cost $5-50. This is why most active onchain activity has migrated to Layer 2 networks.
You don’t need to understand L2s to hold ETH. You do need to understand them the moment you want to do anything onchain. Arbitrum, Base, Optimism, and zkSync are the four you’ll encounter most. Each runs ETH as its gas token, each inherits security from mainnet Ethereum by posting state back to L1, and each charges a small fraction of mainnet gas. Bridging ETH from mainnet to an L2 takes a few minutes and a small gas fee; bridging back takes seven days on optimistic rollups (Arbitrum, Optimism, Base) because of a challenge window built into the design, or minutes on zk rollups.
For a buy-and-hold ETH position that stays in a hardware wallet, L2s are not relevant. For anyone planning to stake, use DeFi, or interact with applications, L2s are where you’ll spend most of your time.
Fees and the real cost of owning ETH
A $1,000 ETH purchase on an advanced interface costs $1-4 in trading fees plus $1-5 in spread. Withdrawal to a self-custody wallet costs $2-20 in network fees depending on congestion. Total round trip: $5-30.
For staking, the ongoing cost depends on the route. Exchange staking takes a flat 25% haircut on yields. Liquid staking via Lido takes around 10%. Solo staking takes nothing but costs hardware, electricity, and your attention.
The mistakes that cost people money on Ethereum
Approving a token for unlimited spend by a malicious contract is the single most common Ethereum-native loss pattern and costs retail holders millions every quarter. When a wallet prompts you to approve a token, set a spending cap rather than unlimited approval where possible. Revoke approvals you don’t recognize using revoke.cash.
Signing a transaction without reading what it does. Rabby’s transaction preview shows you the net effect (what leaves your wallet, what arrives) and the contract being invoked. Read it. If the transaction claims to “claim an airdrop” but is actually transferring your NFTs, you’ll see it in the preview before you sign.
Leaving the bulk of a position on a DEX or lending protocol that hasn’t been audited. The worst DeFi exploits of the last two years have been against protocols that skipped audits, used unaudited forks, or introduced upgrades without review. Stick to Aave, Uniswap, Compound, and Lido for mainstream use; experiment elsewhere with small positions only.
