What Plainyield is for

Plainyield exists to answer one search honestly: how to earn interest on crypto. Most sites answer it with a leaderboard of the highest APYs and an affiliate link. We answer it with the truth — that earning interest on crypto means lending your coins to a company or a contract, that a high rate is a signal of risk rather than reward, and that the biggest names offering it went bankrupt in 2022. We would rather you understand the danger than click a button.

What it will never do

We will never tell you which coin to buy, predict a price, or promise passive income. We will never present a yield product as safe, quote a “guaranteed” high APY, or touch a presale, meme token or fixed-high-yield scheme. What we do is explain the mechanics, name the failures as dated fact, and repeat the least profitable advice in crypto: if you do not understand where the yield comes from, you are the yield — and keeping your coins in self-custody, earning nothing, is a perfectly good choice.

Independent, and plain about it

Some providers pay us a commission if you sign up through a link, and we disclose it every time — but a payout never softens a warning, and the honesty is the entire product. The best recommendation on this site pays us nothing: hold your own keys. Start with whether crypto lending is safe, and read our affiliate disclosure so you know exactly how the site pays for itself. None of this is financial advice.

Common questions

Is earning interest on crypto safe?
No — treat it as high-risk by default. Earning a yield means handing your coins, and the keys, to a company or a smart contract, so on top of crypto's normal volatility you take on the risk that the platform itself fails. In 2022 the biggest names in the sector — Celsius, Voyager and BlockFi — froze withdrawals and went bankrupt, and customers became unsecured creditors owed billions. Some products are more honest than others, but none are 'safe' the way a bank savings account is.
Where does the yield actually come from?
Someone has to pay it, and that someone is usually a borrower, the platform's own trading, or freshly minted tokens used as an incentive. Custodial 'interest accounts' lend your coins out — often re-using the same collateral several times — and pass you a slice. DeFi protocols pay you from the interest borrowers pay, sometimes topped up with token rewards that can inflate away. If a provider can't clearly explain the source, the honest reading is that you are the yield.
Why is a high advertised APY a red flag?
Because yield is priced for risk: the higher the rate, the more risk is being taken with your money to produce it. A double-digit 'guaranteed' return on a stablecoin is not a free lunch — it usually means aggressive lending, leverage, or an unsustainable subsidy. Anchor Protocol advertised around 19.5% on the UST 'stablecoin' right up until UST collapsed in May 2022. A rate that looks too good to be true is information, not opportunity.
Is this the same as staking?
No. Staking means locking coins to help run a proof-of-stake blockchain and earning protocol rewards for securing it; lending or an interest account means handing your coins to a company or contract that lends them out and pays you interest. They carry different risks, and this site covers the lending side — the one with the heavier failure history. If you're researching staking, that's a separate topic with its own trade-offs.
What's the safest way to earn on crypto?
The lowest-risk option is not to lend at all: hold your own coins in self-custody and accept that they earn nothing. That removes the counterparty risk that sank the 2022 lenders entirely. If you still want yield, the honest guidance is to prefer large, regulated, transparent providers, use only money you can afford to lose completely, understand exactly where the return comes from, and never treat any advertised rate as guaranteed. Earning nothing safely beats earning a headline rate you can lose.
