Where can I purchase an X Token?

Excuse me, I'm interested in acquiring some X Tokens, but I'm not quite sure where to start. Could you please provide me with some guidance on the best platforms or exchanges where I can safely and securely purchase these tokens? Additionally, are there any specific factors I should consider before making a purchase, such as fees, security measures, or reputation of the exchange? I'd appreciate any insight you could offer to help me navigate this process and make an informed decision.
