Can I use OKX in the USA?

Could you please clarify for me if it's permissible to utilize OKX within the United States of America? I've been hearing a lot about its features and services, but I'm not entirely sure if it's available or legal in my country. Could you enlighten me on this matter? Is there any specific regulation or policy that I should be aware of before attempting to use OKX in the USA? I'd appreciate it if you could provide me with a concise and clear answer to this inquiry. Thank you in advance for your assistance.
