Is Luno accepted in USA?

Could you please clarify if Luno, a popular cryptocurrency exchange platform, is officially accepted and operational within the United States? As the cryptocurrency landscape evolves rapidly, it's important to stay informed about the availability and regulatory status of various platforms in different regions. I'm specifically interested in knowing if US-based users can utilize Luno's services for buying, selling, and trading cryptocurrencies. Additionally, is there any information regarding potential restrictions or limitations that might affect US customers?
