Is transferring USDT taxable?

I'm a bit confused about the taxation of cryptocurrencies. I understand that transactions involving Bitcoin and other cryptocurrencies may be taxed, but what about USDT? Is transferring USDT taxable? If so, how does the taxation work? Do I need to report every transaction I make? Or is it only taxed when I convert USDT to fiat currency? Also, are there any specific tax regulations or guidelines I should be aware of when dealing with USDT? I'd appreciate it if you could clarify this matter for me. Thank you!
