How do I buy PAXG?

Could you elaborate on the process of acquiring PAXG, a digital asset representing physical gold? I'm particularly interested in the steps I need to take as a beginner in the cryptocurrency space. I've heard about the benefits of owning PAXG but am unsure of the most secure and efficient way to purchase it. What platforms or exchanges support PAXG trading? Are there any specific requirements or verification processes I need to complete before I can make a purchase? Additionally, I'd like to understand the costs involved, including transaction fees and any potential conversion rates. Could you guide me through the entire process from start to finish?
