How to earn USDT for free?

I've been hearing a lot about USDT recently and it sounds like a really convenient way to hold value in the crypto world. But I'm curious, is there a way to earn USDT for free? I know there are various ways to earn cryptocurrencies like staking or mining, but I'm not sure if that applies to USDT as well. Could you explain if there are any legitimate methods to acquire USDT without investing my own funds? It would be great if you could also mention any potential risks or caveats associated with such methods. Thanks in advance for your help!
