Staking is often sold as “earning interest on crypto.” That description is close, but it leaves out most of the risk. This guide explains what crypto staking actually is, using Ethereum as the main example, and how to think about the trade-offs.
What is crypto staking?
Blockchains need a way to agree on which transactions are valid. Bitcoin uses proof-of-work: miners spend electricity to compete for each block. Ethereum switched to proof-of-stake in September 2022 (the “Merge”). Instead of using electricity, validators lock up, or stake, ETH as collateral. They propose and confirm blocks, and they earn rewards for doing it honestly.
If a validator breaks the rules, for example by signing two conflicting blocks, part of its stake can be destroyed. This is called slashing. Because validators have money at risk, they have an incentive to behave honestly.
According to >ethereum.org, rewards come from newly issued ETH plus transaction fees and tips. They are variable, not fixed. They depend on how much ETH is staked overall and on network activity.
Four ways to stake
| Method | What you need | Control | Main risks |
|---|---|---|---|
| Solo staking | 32 ETH, your own hardware, technical skill | Full | Slashing, downtime, operational mistakes |
| Staking as a service | 32 ETH; a provider runs the node | You keep withdrawal keys | Operator mistakes, trust in provider |
| Pooled / liquid staking | Any amount | You hold a token such as stETH | Smart-contract bugs, depeg, protocol governance |
| Exchange staking | Any amount, an exchange account | The exchange holds your coins | Custody, platform failure, terms changes |
Since Ethereum’s Pectra upgrade in 2025, a single validator can hold more than 32 ETH, up to 2,048 ETH. This helps large stakers consolidate, but 32 ETH is still the minimum to run your own validator.
Liquid staking, briefly
Liquid staking protocols such as Lido take your ETH, stake it, and give you a token (stETH) that represents your stake plus rewards. You can use that token in DeFi, for example as loan collateral, while still earning staking rewards.
It is convenient, but it adds layers of risk. The token can trade below the value of ETH during market stress, and you depend on the protocol’s smart contracts and governance. Lido, which has more than $25 billion in stETH, has just proposed its own lending market (our coverage), which shows how deeply liquid staking tokens are now embedded in DeFi.
The risks most people underestimate
- Price risk. Rewards are paid in ETH. If ETH falls 9% in a week, as it did this week to $2,486.58 at 15:25 UTC on Oct. 9 per CoinGecko (our report), a few percent of annual yield won’t make up the difference.
- Liquidity risk. Unstaking on Ethereum requires going through a withdrawal queue, which can take days or longer when many people are exiting.
- Slashing and penalties. These are rare for well-run operators, but they happen.
- Counterparty risk. With exchange staking, you are trusting the exchange. Platform collapses in 2022 locked up many users’ “staked” coins.
- Tax. Many countries tax staking rewards as income when you receive them. Greece’s new draft law, for example, would tax them at 10% as interest (our report).
Is staking regulated?
It depends on where you live. In the United States, the SEC’s Division of Corporation Finance said in a May 2025 >staff statement that protocol staking activities, as described in the statement, generally do not involve the offer or sale of securities. Liquid staking and restaking were outside that statement, and it is staff guidance, not law. Elsewhere, rules vary. In the EU, staking services are increasingly handled within MiCA-licensed providers.
A crypto staking checklist
- Can I afford for this ETH to be locked up for weeks?
- Do I understand who holds the keys: me, a protocol or an exchange?
- What happens to my stake if the provider fails?
- How will my rewards be taxed where I live?
- Is the stated yield realistic? Ethereum staking rewards have been in the low single digits per year. Much higher advertised rates usually mean extra risk, or a scam (how to spot one).
CryptoVank’s take
Staking is a reasonable way for long-term ETH holders to earn a modest return on coins they planned to hold anyway. It is not a savings account. Start with a small amount, choose the simplest option you fully understand, and keep the keys yourself where you can. Our self-custody guide covers the basics.
Crypto staking FAQ
How much do I need to stake ETH?
32 ETH to run your own validator. Pooled, liquid and exchange staking accept smaller amounts.
Can I lose money staking?
Yes, through price drops, slashing, smart-contract failures or the failure of a custodian.
Are staking rewards guaranteed?
No. They vary with network conditions and are paid in ETH, whose price changes.
What is slashing?
A penalty that destroys part of a validator’s stake if it breaks protocol rules, such as signing conflicting blocks.
