How do I sell USDT to cash?

I'm a bit puzzled about converting my USDT holdings into cash. Could you guide me through the process? I've heard about various platforms and methods, but I'm not sure which one is the most secure and efficient. Do I need to go through a broker or an exchange? Are there any fees involved? And most importantly, how can I ensure the safety of my transactions? I'd really appreciate your insights on this matter.
