In crypto, yield does not mean money generated from thin air.

When a protocol offers returns on digital assets, that value usually comes from a specific activity: transaction validation, lending, liquidity provision, fees paid by users, or incentives distributed by the protocol itself.

Before seeking yield, it is worth understanding where it comes from, what costs may arise, and what risks are involved.

A high APY may grab attention, but on its own, it does not show factors like asset volatility, smart contract risk, exit liquidity, network fees, or impermanent loss.

For those who are still getting familiar with the universe of digital assets, the belo app can be a starting point to follow the options to receive, convert, and move assets.

Where the money that crypto "generates" comes from

When you see a protocol offering high yields on a crypto deposit, the first question should be: who is paying for this? 

If the answer doesn't appear in less than two minutes of research, the risk is probably greater than the yield justifies.

Every yield in crypto assets has a concrete origin. It fits into some mechanisms that work similarly to the traditional economy, only without the banking intermediaries.

Main yield mechanisms in crypto

• Staking: you lock your tokens to help validate transactions on the network, and the network rewards you with new tokens for this service.

• Protocol lending: you deposit crypto into a pool, and another person borrows it by paying interest, which is distributed among depositors. The rate varies according to the supply and demand for that asset.

• Liquidity provision on DEXs: you deposit token pairs into a pool that allows other people to make swaps, and you receive a fraction of the trading fees as payment.

• Protocol incentives: extra tokens that projects distribute to attract users and liquidity quickly. These incentives tend to decrease over time.

• Yield through inflation: rewards come from the creation of new tokens, which can dilute the value of what you already own if the demand for the asset does not grow in the same proportion.

Specific risks of each mechanism

Understanding where the yield comes from is half the job. The other half is mapping what can go wrong. Each mechanism has a different vulnerability.

In staking, the most direct risk is slashing: a penalty that the network applies when the validator to which you delegated your tokens makes mistakes or acts inappropriately. Part of the locked value can be reduced.

In lending protocols, smart contract risk is central. A bug in the code can allow an attacker to drain the entire pool, and there is no bank insurance to cover this.

In liquidity provision, the concept of impermanent loss is the most treacherous. When the relative price of the two tokens in the pool changes significantly, you can end up with less value than you would have if you had simply kept the tokens in your wallet.

The higher the advertised APY, the higher the probability that at least one of these risks is amplified. 

Protocols that offer yields far above standard levels generally rely on inflationary incentives in tokens that lose value quickly, or operate with unaudited contracts.

What is left after costs

An APY looks attractive until you do the full math. Gas fees to deposit and withdraw already consume a portion of the return. If you need to make multiple transactions over the period, the accumulated costs can be significant.

The time variable also changes this equation decisively. In shorter periods, transaction fees weigh proportionally much more.

For smaller amounts, the net yield in many protocols can be close to zero or even negative when fees and other deductions are added. Always check the displayed values before confirming any operation.

Five essential questions before allocating capital

1. What is the source of the yield? If you cannot explain where the money comes from in one sentence, it is worth researching further before depositing.

2. What is the TVL (total value locked)? Protocols with very low TVL tend to be riskier.

3. Are there safety audits conducted by recognized companies?

4. How does custody work? Who controls the private keys of the deposited funds?

5. What is the exit liquidity? Can you withdraw your capital when you need to, or is there a lock-up period?

Comparison: yield mechanisms in crypto

Mechanism · How it generates yield · Main risk · What to check

Staking · Validation of network transactions · Slashing, lock-up period · Unlock period, validator reputation

Protocol lending · Interest paid by borrowers · Smart contract, illiquidity · Audit, TVL, utilization rate

Liquidity provision · Trading fees from the pool · Impermanent loss · Price divergence between tokens

Protocol incentives · Tokens distributed to attract liquidity · Depreciation of reward tokens · Liquidity and market of distributed tokens

If you are still building familiarity with the crypto universe and prefer to start more gradually, on belo you can follow the options to receive, convert, and move digital assets through the app.

The guide on cryptocurrencies in the belo help center can also be a good foundation before exploring yield protocols.

Crypto yield can have different origins, and each mechanism brings its own risks. Therefore, before operating, the most important thing is to understand where the return comes from, what costs may appear, and what conditions the protocol presents.

Frequently asked questions about How yield works in crypto

Is it possible to have risk-free yield in crypto?

There is no risk-free yield in crypto assets. Even stablecoins can present liquidity problems or lose parity with the dollar. What you can do is seek to minimize risks by choosing audited protocols with a solid track record and significant TVL. If in doubt, consult the belo help center or a specialized professional.

Is it worth seeking high yields with small amounts?

For smaller amounts, transaction fees can consume a large part of the yield, especially on networks with higher gas costs. Check the total costs before confirming any transaction and assess whether the expected return compensates for these costs.

How to evaluate if a protocol is trustworthy?

Check if it has published safety audits, significant TVL, a identifiable team, and transparency about how it generates yield. Protocols that offer very high yields without a clear explanation deserve extra caution.

What to do if the protocol I invested in suffered an attack?

Unfortunately, there is no guarantee like in the traditional banking system. The loss can be total. Therefore, it is fundamental to diversify, not allocate more than you can afford to lose on a single platform, and prioritize protocols with a proven safety history. Always keep records of your operations.
