Where can I buy Luna Classic?

I'm interested in purchasing Luna Classic, but I'm not entirely sure where to start. Could you please guide me through the process of acquiring this cryptocurrency? I've heard about various exchanges and platforms, but I'm not sure which one is the most reliable and secure for making such a transaction. Additionally, I'm also curious about the steps involved in setting up an account, depositing funds, and ultimately executing the purchase. I'd appreciate any advice or insights you have on this matter, as I'm eager to expand my crypto portfolio.
