I'm seeing a lot of people confused about what APY is in cryptocurrencies. I'll try to simplify this because it's very important for those who want to invest.

Basically, APY is the Annual Percentage Yield — that number that shows how much you can earn in a year considering compound interest. Unlike APR, APY takes into account that 'interest on interest' effect, you know? It’s when you earn returns and those returns generate more returns. This significantly changes the final calculation.

To be honest, most people don’t really understand the difference well. APR is just the interest rate without compounding, while APY already includes that effect. Imagine: a cryptocurrency with an APR of 2% can turn into 3% APY because the gains are reapplied. It seems small, but over longer periods, it makes a difference.

The formula is a bit technical: APY = (1 + r/n)^(nt) - 1. But what matters is that in cryptocurrencies, there are more variables — market volatility, liquidity risks, smart contract risks. All of this affects the final result.

Now, there are basically three ways to earn APY in crypto:

The first is lending cryptocurrencies. You lend your assets on a platform, the borrower pays interest, and you receive an agreed-upon APY. Very straightforward.

Then there’s yield farming, which is riskier. You move your assets to different protocols seeking the highest yields. APYs can be high, but risks also increase, especially with new platforms.

And there’s staking too, which is when you lock your cryptocurrency in a blockchain network. This generates rewards and usually results in a more attractive APY, especially on proof-of-stake networks. It’s safer than yield farming.

But here’s the important part: understanding what APY is is just the beginning. You need to evaluate market volatility, your own risk appetite, liquidity risks. Each investment type has its advantages and disadvantages. APY is an essential metric, but it’s not everything. I recommend doing thorough research before putting money into any crypto yield strategy. Gate has several options to explore if you want to learn more about this.
