Where can I buy Moonbeam?

I'm interested in purchasing Moonbeam, but I'm not sure where to start. Could you please guide me on the best platforms or exchanges where I can safely and securely buy Moonbeam tokens? Are there any specific requirements or steps I need to follow to ensure a smooth transaction? Additionally, are there any fees or commissions associated with buying Moonbeam on these platforms, and how do they compare to other options? I'd appreciate any insights or recommendations you may have to help me navigate this process.
