Could you please clarify for me whether PrimeXBT is available for use in the United States? I'm interested in exploring its services but I'm not sure if there are any regulatory restrictions or limitations that prevent me from accessing it as a US resident. Could you provide me with more information on this matter? Additionally, if there are any specific states or regions within the US where PrimeXBT is accessible or restricted, I would greatly appreciate your insights on that as well. Thank you in advance for your assistance.
