Can I use BYDFi in the USA?

Hello there, I was wondering if you could help me with a question regarding BYDFi. I'm considering using it for my financial transactions, but I'm unsure if it's available or even legal to use in the United States. Do you have any information on the accessibility and legality of BYDFi in the USA? Additionally, if there are any potential restrictions or limitations that I should be aware of, could you please elaborate on those as well? Thank you for your time and assistance.
