Is Paxful allowed in the USA?

Are there any restrictions or limitations for Paxful users in the United States? I'm interested in knowing if Paxful is a viable option for buying and selling cryptocurrency in the US, and if there are any specific rules or regulations that Paxful users in the country need to be aware of. Additionally, is Paxful's service fully functional and accessible to US residents, or are there any geographical limitations that might affect my ability to use the platform?
