How to buy Omega Network?

Good afternoon, I'm interested in purchasing Omega Network tokens, but I'm not entirely sure how to proceed. Could you provide a step-by-step guide on how to buy Omega Network? I've heard about cryptocurrency exchanges but I'm not entirely familiar with the process. Could you also explain the necessary prerequisites, such as setting up a wallet and understanding the risks involved? Additionally, I'd like to know if there are any specific exchanges that support Omega Network and whether there are any recommended wallets for storing the tokens. Thank you for your assistance.
