What is the best site to sell USDT?

I'm looking to sell some USDT and I'm not sure where to start. Could you recommend the best site for this? I've heard there are a lot of options, but I want to make sure I choose a reliable and secure platform. I'm also concerned about transaction fees and how quickly I can convert my USDT into fiat currency. Could you provide some insights into the process and any potential risks I should be aware of? Thank you for your help.
