How to Earn Interest on Crypto: Staking, Lending or Earn?

To earn interest on crypto, choose a mechanism that fits the asset you intend to keep and when you need it back: network staking, lending, or an eligible platform Earn product. A higher advertised percentage can come with a different asset exposure, withdrawal process or cost.

“Interest” is often used loosely. Borrowers fund lending returns, network participation earns staking rewards, and platform rewards follow product-specific arrangements. The first step is identifying which mechanism you are actually using.

Keep the asset decision separate from the yield decision

Ethereum’s official documentation describes staking as putting ETH at stake to secure the network and earn rewards. It is a route to evaluate if you already intend to hold ETH. Buying ETH just to stake it when your goal was to retain USDT changes the principal’s price exposure.

USDT is not Ethereum’s native staking asset. A USDT earning product needs to be evaluated by its actual financial mechanism. The crypto staking guide explains the network role behind staking rewards.

These are mechanism categories. Products within one category can still have different risks and withdrawal conditions.

What each earning route requires

Staking: commit the network’s native asset

Ethereum users can operate a validator or use pooled or service-based staking. Ethereum’s withdrawal documentation notes that exit timing depends on network demand, while pools have their own handling rules. Selling a liquid staking token and redeeming it for underlying ETH are different exits. Staking retains ETH price exposure and can add validator, operator or smart-contract risks, depending on the route.

Lending: supply liquidity to borrowers

Aave’s Supply Tokens guide describes transferring supported assets into a smart-contract liquidity pool. Borrowing utilization and governance parameters affect the supply rate, so returns can change with market conditions.

Its withdrawal guide makes access conditional on sufficient pool liquidity. If your supplied assets support an active borrowing position, withdrawing them may require debt repayment or additional collateral. Wallet control does not make supplied assets immediately spendable.

Platform Earn: qualify under the account’s rules

MEXC’s Futures Earn page describes interest on eligible futures-account funds after activation, while normal futures trading can continue. The asset, account and balance must meet the product’s current requirements.

Check how earnings are recorded, too. The guide to yield-bearing stablecoins versus account rewards distinguishes credited account rewards from changes in a token position’s redemption value.

Calculate returns over your actual holding period

Consider a hypothetical $1,000 position earning a constant 5% simple annual rate, using 365 days. Over 30 days it generates approximately $4.11 before costs: $1,000 × 0.05 × 30 ÷ 365.

If entering and exiting costs $12 in total, the net result is about -$7.89. Earning back that $12 would take about 88 days at the unchanged rate and principal. The example excludes compounding, taxes and asset-price changes; it is not a current product quote or a forecast.

MEXC’s editorial assessment is that a short-duration yield comparison should include the complete entry and exit cost. Network charges, conversion spreads or withdrawal fees can outweigh a small position’s earnings well before differences between quoted annual rates become meaningful.

Risk warning

Crypto yield can involve asset-price losses, smart-contract failures, custody risk, penalties or delayed withdrawals. A yield feature does not protect a leveraged trading position from liquidation.
