How do you buy cube coins?

I'm curious about the process of acquiring cube coins. Could you please walk me through the steps involved in buying them? Are there any specific exchanges or platforms that I should be aware of? Are there any prerequisites or verification processes I need to complete before I can make a purchase? Additionally, is there a minimum or maximum amount that I can buy, and what are the associated fees? I'm eager to learn more about the ins and outs of acquiring cube coins, so any information you can provide would be greatly appreciated.
