Earning interest on crypto: how it works, and why it's dangerous

What “earning interest on crypto” actually means

Earning interest on crypto means giving your coins to someone else — a company or a piece of software — that puts them to work and pays you a share of what it makes. It is not like leaving cash in a bank. A bank deposit is a regulated, insured claim; a crypto interest account or lending position is an unsecured loan you make to a private business or a smart contract, with no deposit insurance behind it. That single difference is the whole story of this page, and it is why we treat the entire category as high-risk by default.

There are a few flavours of this: custodial “interest accounts” run by centralised firms (CeFi), lending through decentralised protocols (DeFi), and “stablecoin yield” that pays you for parking a dollar-pegged token. People often lump in staking, but staking is a different mechanism with different risks. Before any of it, read the honest answer to whether crypto lending is safe — in short, mostly no. The rest of this guide explains why, and what to check if you decide to do it anyway.

Where does the yield come from?

The yield comes from someone paying to borrow, from the platform trading with your coins, or from freshly printed tokens handed out as an incentive. Interest is never created from nothing. When a provider offers you a return, trace it back: a borrower is paying interest, the company is lending or trading your assets (sometimes re-using the same collateral several times over, a practice called rehypothecation), or a project is minting new tokens to lure deposits. Each of those sources can dry up or blow up, and when it does, your principal — the coins you deposited — is what is on the line.

This is the single most useful habit you can build: before depositing anything, make the provider’s explanation of the yield concrete. “We generate returns through market-neutral strategies” is not an answer. Our full guide to why high crypto yields are a red flag walks through the common sources one by one, and how to tell a real one from a Ponzi that simply pays old depositors with new deposits.

The main ways to earn — and how they differ

The four approaches below differ mainly in who holds your coins and what can go wrong. Custodial (CeFi) lending is the most convenient and the one with the worst failure record; DeFi lending replaces the company with code, trading counterparty risk for smart-contract risk; stablecoin yield adds the risk that the “stable” part fails; and staking is a genuinely different thing we include only to keep it separate. The table compares them on the axes that actually matter — not the headline rate.

The CeFi–DeFi split is worth understanding before you choose, because the risk you are taking is genuinely different in kind. Our guide to CeFi vs DeFi lending risk compares the two head-on: with CeFi you trust a company’s solvency and honesty; with DeFi you trust code, and code can be exploited in seconds and cannot be reasoned with.

Why a high advertised rate is a warning sign

A high advertised APY is a signal that more risk is being taken with your money, not that you have found a better deal. Yield is the price of risk: safe, liquid, well-collateralised lending pays little, so a double-digit “guaranteed” return has to be manufactured somewhere — through leverage, through lending to riskier borrowers, or through token subsidies that cannot last. When you see a rate that dwarfs anything a bank or bond offers, the correct response is more suspicion, not more enthusiasm. The rate is information about the risk, and the risk is the part that can take your principal to zero.

Advertised rates are also not guaranteed, and they change constantly. A platform can cut its rate the day after you deposit, apply it only to a small “intro” balance, or gate the best tier behind holding its own token. Because these numbers move so often and mean so little about safety, this site deliberately does not publish live APYs — anyone quoting a fixed, guaranteed high yield on a volatile asset is telling you something important about themselves. Always check the provider’s current, advertised, not-guaranteed rate yourself, and weigh it against everything else here.

What happened in 2022 — the history you can't unlearn

In 2022 the largest crypto “interest” businesses collapsed within months of each other, and retail customers lost billions. This is not ancient history or a fringe event — it was the mainstream of the sector, the companies with the biggest ad budgets and the most trusted names, and they went to zero for their depositors. Any honest guide to earning interest on crypto has to put this record first, because the marketing that preceded each collapse looked exactly like the marketing you will see today.

Celsius froze withdrawals in June 2022 and filed for bankruptcy owing customers about $4.7 billion; its founder was later sentenced to 12 years for fraud. Voyager and BlockFi followed. Terra’s UST — a “stablecoin” paying around 19.5% — lost its peg and wiped out roughly $50 billion.

“Not your keys, not your coins” applies to earning too

To earn a yield you must give up control of your coins, and control is the thing that keeps them yours. The old crypto maxim — not your keys, not your coins — is usually said about exchanges, but it applies just as hard to lending: the moment you deposit into an interest account or a protocol, you no longer hold the keys, and you are trusting someone else to give the coins back. The ladder below shows the trade-off. More yield almost always means handing control to someone with more ways to lose it, and our guide on why “not your keys” applies to lending goes deeper.

If you still want to earn: a harm-reduction checklist

If you decide to earn a yield anyway, treat it as speculation with money you can afford to lose entirely, and run through this list first. None of it makes the activity safe — it only reduces how badly a failure can hurt you.

• Can you explain where the yield comes from in one plain sentence? If not, stop.
• Only commit money whose total loss would not change your life — rent, savings and emergency funds are off-limits.
• Prefer large, transparent, regulated providers over anonymous ones promising the biggest number.
• Assume any advertised rate can be cut or the product paused at any time, and that withdrawals can be frozen exactly when you most want out.
• Check whether the product is even legal and available where you live — eligibility differs by country and changes.
• Remember that any interest you earn is likely taxable as income in your country, even if you never sell the coin.

The providers people ask about — with the caveats attached

A handful of large, still-operating firms offer earn products, and none of them are “safe” the way a bank is. Nexo survived 2022 but settled with the SEC and state regulators for $45 million in January 2023 over its US Earn Interest Product, withdrew from the US, and only returned in April 2025. Coinbase is a large US-listed exchange offering USDC rewards and other earn features, but those rewards are not bank interest and are not insured. Crypto.com likewise offers earn products with the same counterparty and platform risk. Those three links are affiliate links — if you sign up we may earn a commission at no cost to you, and it changes nothing on this page. We would rather you read the risks first, and we say plainly that keeping your coins in self-custody and earning nothing is a legitimate, often better choice that pays us nothing.

The honest alternative: earn nothing, keep control

The lowest-risk way to hold crypto is to hold your own coins and earn no interest at all. It sounds anticlimactic, and it is exactly the point: by not lending, you remove the counterparty risk that sank every failed lender in 2022. There is no company that can freeze your withdrawal, no contract that can be drained, and no yield that can evaporate — just the underlying volatility of the asset, which is risk enough. For many people the right amount of crypto yield to chase is zero, and choosing that on purpose is not missing out; it is refusing to hand your coins to the next Celsius.

If a return looks too good to be true on an asset this volatile, it is telling you the truth about the risk, not offering you a shortcut. The safest yield in crypto is often the one you decline.
