How to buy GMT?

I'm curious about how one would navigate the process of purchasing GMT, a cryptocurrency that has piqued my interest. Could you walk me through the steps involved in acquiring GMT tokens? I'm particularly interested in understanding which platforms support GMT trading, whether I need to set up a digital wallet, and what factors I should consider in choosing a reliable exchange. Additionally, I'd like to know if there are any specific requirements or limitations for purchasing GMT, such as geographical restrictions or minimum investment amounts. Clarifying these details would greatly assist me in my pursuit of acquiring GMT.
