CEX.IO Earn Review: Licence-First Staking and Savings

Two products, deliberately kept apart

Almost every exchange in this market has an Earn tab that lists assets and percentages in a single column. Staking sits next to lending, protocol rewards sit next to borrower interest, and nothing on the screen tells you which is which. It is the most common design in the category and it is a genuine information failure.

CEX.IO splits them. Staking covers proof-of-stake assets and pays rewards minted by those networks, distributed monthly. Savings is described plainly as a lending service, with interest accruing daily, currently offered as a flexible account with no fixed-term tier. Where an asset appears in both — SOL at 5% staking and 4% savings, ADA at 1.5% staking and 2% savings — you can see both numbers and choose knowingly.

That ADA pairing is worth dwelling on, because it is the kind of thing this separation makes visible. Savings pays more than staking on Cardano. A blended interface would show you 2% and you would take it. Here you can see that the 2% comes from lending and the 1.5% comes from protocol issuance, and decide whether half a percentage point is worth introducing borrower credit risk. Most people, told the difference, would take the 1.5%.

The no-lock-up question, and why it matters more than it looks

Cosmos imposes a 21-day unbonding period at the protocol level. Polkadot imposes 28. These are not platform choices — they are consensus rules designed to stop a validator misbehaving and immediately withdrawing its stake. Almost every venue passes that delay straight through to the customer, and a few add their own on top.

CEX.IO states that there is no lock period and staked coins can be withdrawn at any time. That means the platform is maintaining a liquidity buffer and absorbing the timing mismatch itself. It is a real cost to the business, and it explains why the published rates sit below what direct nomination would yield — 6% on DOT here against roughly 10% to 13% nominating directly and accepting the 28-day exit.

Whether that is a good trade depends entirely on you. If you are a committed long-term holder who genuinely will not need access, direct nomination pays considerably more. If there is any realistic chance you will want to move within a month — and in an asset class this volatile, there usually is — then 6% you can exit is worth more than 12% you cannot. Our Polkadot page works through that arithmetic in detail.

Licensing, stated entity by entity

"Regulated" is the most abused word in crypto marketing. It is usually deployed without naming the entity, the regulator or the scope — and in this market those three details are the entire substance of the claim.

CEX.IO is specific. CEX.IO Markets UK Limited holds a cryptoasset registration with the UK Financial Conduct Authority, which also permits it to communicate qualifying cryptoasset financial promotions to UK consumers under the country's updated standards. CEX.IO Limited is authorised and regulated by the Gibraltar Financial Services Commission as a DLT provider under authorisation number FSC0686FSA. CEX.IO Corp has been registered with FinCEN as a money services business since 2015. The group also holds a CySEC CIF licence in Cyprus and Bank of Spain virtual asset service provider status, and has been building out a Lithuanian presence including a dedicated money laundering reporting officer.

Every one of those is verifiable on a public register, which is the point. We checked the Gibraltar authorisation number against the FSC's own listing, and the FCA registration against the financial services register.

The necessary caveat applies here as everywhere: none of these registrations means a regulator has approved the earn products. Registration is an anti-money-laundering and conduct framework, not a product endorsement, and there is no deposit insurance behind any of it. In the European Union specifically, MiCA authorisation does not extend to crypto lending programmes at all — the European Commission has named lending and staking as gaps beyond MiCA's original scope, with a consultation running to 30 September 2026. That caveat applies to every platform in this market equally; it is simply easier to state here because the underlying facts are actually disclosed.

Why Bitcoin pays 0.25% here, and why that is informative

The BTC savings rate is the lowest number on the whole rate card and the first thing critics point at. We read it differently.

Bitcoin interest rates are low everywhere, because almost nobody wants to borrow BTC — the demand in crypto lending is overwhelmingly for dollars. A platform paying 5% on Bitcoin is running an aggressive lending book against customer BTC or subsidising the rate for acquisition. A platform paying 0.25% is largely holding it.

For an asset most people intend to keep for years rather than optimise for yield, that is a defensible product decision, and it is consistent with everything else about how this platform is positioned. If Bitcoin yield specifically is what you want, Ledn pays up to 5.25% below 0.5 BTC with published proof-of-reserves attestations, and we cover the full landscape on our earn Bitcoin page. Just be clear that you are buying a different product with a different risk profile, not finding a better version of the same one.

Verdict

CEX.IO Earn is the platform we point people to when they ask where to start. It scores 4.6 out of 5 — the highest in our database — not because it pays the most, but because it does the unglamorous things properly. Staking and lending are presented as two separate products with separate rates, so you always know whether your yield is minted by a protocol or owed by a borrower. Staked coins carry no lock-up, which quietly removes the single biggest practical objection to staking. Savings interest accrues daily from the first dollar with no minimum and no tier table to decode. And the licence position is stated entity by entity rather than as a vague claim of being regulated. The trade-offs are real and clearly visible: Bitcoin savings at 0.25% is deliberately conservative, there is no fixed-term tier for savers who want to commit capital for a higher rate, and the asset menu is smaller than the largest global exchanges. For anyone chasing a 9% headline, this is not the venue. For anyone who wants to understand exactly what they have bought, it is the best-documented product we have reviewed.

The facts, on one page

Licence and registration details are as published by the provider and, where possible, checked against the relevant public register. Registration of a firm does not mean a regulator has approved, endorsed or guaranteed its earn products — in the EU, MiCA authorisation specifically does not extend to crypto lending programmes. Verify current status on the FCA register or the relevant authority for your jurisdiction.

Who this platform is not for

Anyone whose primary criterion is the highest available number should look elsewhere and will be happier for it. Nexo advertises up to 9.5% on USDT and 13% on DOT at its top tier; YouHodler reaches into the teens on stablecoins; Ledn pays 8.5% on USDC above $100,000. Those rates are real, and this platform does not compete with them.

Anyone wanting a fixed-term savings tier is also out of luck for now — the platform's own FAQ states it does not currently provide a locked savings option, though it points at future features. Savers who want to commit capital for 90 days in exchange for a higher rate will need to look at Bitget or OKX, and should read our flexible versus locked analysis first, because the premium on offer across the market is often smaller than it should be.

And anyone holding a long tail of smaller tokens will find the menu narrow. Thirteen staking assets and around twenty savings assets is respectable, but KuCoin supports well over two hundred. That breadth comes with its own costs, which we cover in our KuCoin review.
