How do I pay for Dext?

How do I go about paying for Dext? I'm interested in purchasing some of the cryptocurrency, but I'm not sure what steps I need to take. Is there a specific exchange that I should use, or can I pay directly from my wallet? Are there any fees associated with the purchase, and if so, how much are they? I'd also like to know if there are any restrictions on who can buy Dext, and if there are any special requirements I need to meet. Can you provide me with a step-by-step guide on how to pay for Dext?
