Telegram wallet in US

Okay. I can tell from this forum that using telegram wallet is incredibly risky.

That said if I am willing to lose the money that I put into it, what is the best way as an american to use it? Can I buy USDT from say coinbase, transferred into my telegram wallet and use my american phone number connected account to use said currency?

For everything I'm reading I would only do it with money that I'm willing to totally lose and I have a reason to want to do it this way.
