How to buy mav token?

Excuse me, could you possibly elaborate on the steps required to purchase MAV tokens? I'm new to this and a bit unsure of the process. Is there a specific platform or exchange that I should be using? Are there any prerequisites or requirements that I need to fulfill before I can make the purchase? Also, could you provide any guidance on how to safely and securely store my MAV tokens once I've acquired them? Thank you in advance for your help.
