Can you buy USDT with cash?

I've been hearing a lot about cryptocurrency and I'm particularly interested in USDT. But I'm a bit confused about the purchase process. Can you buy USDT with cash directly? Or do I need to go through some sort of exchange or platform? Also, if I can use cash, where can I do so? Are there any specific locations or online platforms that accept cash payments for USDT? I'd really appreciate it if you could clear up this confusion for me. After all, I'm eager to get started in the world of cryptocurrency but I want to make sure I'm doing it right.
