Where can I buy Akash Network?

I'm interested in purchasing Akash Network tokens but I'm unsure where to start. Could you please provide some guidance on where I can buy Akash Network safely and securely? I've heard about decentralized exchanges and centralized platforms, but I'm not sure which is the best option for me. Additionally, I'd like to know if there are any specific requirements or steps I need to take before making a purchase. Your insights would be greatly appreciated.
