Staking

Staking is the process of locking cryptocurrency in a blockchain network to help validate transactions and maintain network security, in return for rewards — typically paid in the same token. For most retail users, staking happens through an exchange (like Coinbase or Kraken) which handles the technical process and pays out rewards after taking a commission. Staking yields vary by asset and carry liquidity, smart contract, and market risk.

In plain terms, staking is a way to earn passive income on certain cryptocurrencies by 'locking them up' to support the network. Think of it like earning interest on a savings account — except the 'interest' is paid in crypto, fluctuates, and the value of what you earn (and what you staked) can go up or down significantly.

Staking can generate yield on assets you intend to hold long-term, but the commission taken by exchanges varies significantly — Coinbase retains 25-35% of rewards, while competitors often charge 10-15%. The headline APY shown by exchanges is after their commission, but this is not always clearly disclosed. Additionally, lock-up periods mean you cannot sell or transfer staked assets during volatile markets, which is a meaningful liquidity risk.

When comparing exchanges on staking, evaluate: commission rate on rewards (Coinbase 25-35%, Kraken varies by asset, Crypto.com varies), supported assets for staking, lock-up periods and flexibility, clarity of disclosed APY (is it before or after commission?), and whether staking is available for UK users on that specific asset. Some assets are restricted from exchange staking in the UK under FCA rules.

• Staking assets you may need to sell during a market decline — lock-up periods prevent exit.

• Not accounting for exchange commission when projecting staking returns.

• Confusing staking APY with a guaranteed return — it is variable and paid in a volatile asset.

• Assuming all assets can be staked: only proof-of-stake coins are stakeable (Bitcoin cannot be staked).

Risk note: staking involves locking up volatile assets. The value of rewards and staked principal can fall significantly. There is no compensation scheme for staking losses.

You stake 1 ETH on Coinbase with an advertised APY of 3.5%. Coinbase retains ~30% of raw rewards, so the true network yield is closer to 5%. Over a year, you receive approximately 0.035 ETH in rewards. If ETH's price has fallen 30% over the year, the combined value of your ETH and rewards is lower than your starting position, despite earning staking income.
