How to purchase mbx?

Excuse me, could you please elaborate on the process of purchasing MBX tokens? I'm a bit new to the cryptocurrency world and I'm interested in acquiring some MBX. Could you guide me through the steps, including where I can find a reputable exchange to buy them from, what payment methods are accepted, and any potential fees or considerations I should be aware of? Additionally, is there a minimum purchase amount or any other restrictions I should know about? Thank you in advance for your assistance.
