How do people make money with USDT?

I'm curious about the mechanics of earning money with USDT. Could you please explain it to me in a simple yet comprehensive manner? I understand that USDT is a stablecoin pegged to the value of the US dollar, but how does it generate returns for investors? Are there specific strategies or platforms that are more profitable than others? Also, what are the risks involved, and how can they be mitigated? Thank you for your time and assistance.
