Where can I buy XLM?

Excuse me, I'm interested in purchasing XLM, but I'm not quite sure where to start. Could you possibly direct me to a reliable platform or exchange where I can safely buy XLM? I've heard about a few options, but I'm not certain which one offers the best security, user-friendliness, and variety of payment methods. Additionally, I'd like to know if there are any specific requirements or steps I need to take before making a purchase. Could you please provide some clarity on this matter? I appreciate your help in navigating this process.
