How to earn profit on USDT?

I'm quite curious about earning profits on USDT. Could you please elaborate on the strategies one could adopt to achieve this? I've heard about trading pairs and leveraging positions, but I'm still a bit hazy on the details. Is it necessary to have extensive knowledge of market fluctuations to be successful in this? Or are there simpler methods suitable for beginners like me? Also, what are the potential risks involved, and how can I mitigate them? I'd appreciate it if you could provide some insights on these matters. Thank you in advance for your help.
