TL;DR: Staking lets your crypto work for you while you hold it. You earn rewards just for participating in a blockchain network. Think of it like interest on savings, but for crypto.Here's how it actually works.

Crypto staking explained simply: you lock up a portion of your cryptocurrency to help run and secure a blockchain network. In return, that network pays you staking rewards: extra crypto credited to your wallet over time.

It's not magic. The network needs your coins to function, and it compensates you for contributing them. The more you stake, the more you can earn.

Not every cryptocurrency supports staking. It only works on blockchains that use a system called Proof of Stake (PoS). More on that below.

Why does staking exist? Proof of Stake, explained.

Bitcoin uses "mining": thousands of computers racing to solve puzzles to validate transactions. It works, but it burns an enormous amount of energy.

Proof of Stake is the smarter alternative. Instead of computing power, it uses economic commitment. Validators lock up their own coins as collateral. That gives them the right to validate transactions and add new blocks to the chain.

Here's how it plays out:

• Validators are selected at random, but proportionally. The more you stake, the better your odds.

• Selected validators confirm transactions and earn staking rewards (new tokens minted by the network).

• Validators who go offline or try to cheat get "slashed" and lose part of their stake as a penalty.

Proof of Stake powers Ethereum, Cardano, Solana, and many others. It uses a fraction of the energy Bitcoin mining requires. At scale, that's a significant difference.

How staking rewards work

Here's the flow, step by step:

1. You lock up your coins via a staking wallet or a platform like bunq.

2. The network selects validators based on how much is staked.

3. Validators confirm transactions and add them to the blockchain.

4. Rewards are distributed to validators and to everyone who delegated coins to them (that's you).

Rewards are typically quoted as an APR (Annual Percentage Rate): the percentage of your staked amount you'd earn over a year, assuming the rate holds. Rates vary by coin and change with network conditions. They're never guaranteed.

Is staking crypto safe?

This is the question worth asking before you start. The honest answer: staking carries real risks, and it's important to understand them.

Risks to know

Price volatility

Staking rewards are paid in the same crypto you staked. If that coin's market value drops significantly, your rewards and your principal are both worth less in euro terms. Staking doesn't protect you from market moves.

Lock-up periods

Many staking protocols require you to lock your coins for days or weeks. During that window, you can't sell, even if prices move sharply.

Validator risk and slashing

If the validator your coins are delegated to goes offline or breaks the rules, part of your stake can be slashed (penalized). Choosing a reliable platform matters.

Technical and security risks

Staking happens on online platforms, which means software bugs, outages, or hacking attacks are possible. No platform is immune to these risks entirely.

No regulatory protection (yet)

Staking is currently unregulated in the EU/EEA. Unlike a traditional savings account, there is no deposit guarantee scheme or legal protection if something goes wrong.

What makes staking safer in practice

• Use a regulated platform. bunq is a licensed European bank. Crypto staking through bunq is provided by Kraken (Payward Europe Solutions Limited), authorized by the Central Bank of Ireland.

• Don't stake more than you can afford to hold. Price swings are real. Only stake an amount you're comfortable keeping for a while.

• Understand what you're staking. Different coins, different rules. Ethereum's staking mechanics are well-documented and worth reading before you start.

The benefits of staking

The risks are real. So are the benefits, when you go in with eyes open.

Passive income in crypto

You earn staking rewards simply by holding coins you were planning to keep anyway. You don't need to trade actively to grow your position.

You're supporting the network

Your stake contributes to the security and efficiency of the blockchain. It's a direct way to participate in the ecosystem, not just observe it.

More energy-efficient than mining

Proof of Stake uses vastly less electricity than Bitcoin's Proof of Work. If the environmental footprint of crypto matters to you, PoS coins are the cleaner option.

Flexible staking with bunq and Kraken

One thing that sets bunq apart: no lock-up period.

Most staking protocols tie up your coins for days or weeks. With bunq and Kraken, staking is flexible. You can unstake and withdraw at any time. You keep access to your crypto while still earning staking rewards.

That matters most when markets move quickly, or when you simply want to stay in control of what you own.

bunq lets you start investing in crypto from as little as €1. Staking is available directly in the app alongside your other crypto holdings.

Common staking terms

FAQ: Crypto staking explained

What is crypto staking in one sentence?
You lock up crypto to help secure a blockchain, and the network pays you staking rewards for it.

Which cryptocurrencies support staking?
Only those using Proof of Stake, including Ethereum, Cardano, and Solana. Bitcoin does not support staking.

How much can you earn from staking?
It depends on the coin, the network, and current conditions. Rates are variable and not guaranteed. Always check the live rate in the app before staking.

Can you lose money staking crypto?
Yes, if the price of the coin drops, or if the validator is slashed. Staking rewards don't offset a significant price decline.

Do I need technical knowledge to start?
Not with bunq. Staking is built into the app, so there are no wallets to set up and no validators to choose manually.
