How to buy AI USDT?

Could you please elaborate on the process of purchasing AI USDT? I'm interested in understanding the steps involved, from signing up on a cryptocurrency exchange to successfully acquiring the AI USDT tokens. Could you also highlight any specific requirements or considerations that I should be aware of? Additionally, if there are any security measures or best practices that I should follow while making the purchase, it would be great if you could mention those as well. Thank you for your assistance in this matter.
