How to buy $cwif?

Excuse me, could you please clarify how one might go about purchasing $cwif tokens? I'm new to the world of cryptocurrency and would greatly appreciate any guidance you could provide. Is there a specific exchange or platform where I can buy them? Do I need to set up a digital wallet first? Are there any fees associated with the purchase? Lastly, is there a recommended minimum amount to invest in $cwif, or can I start with a smaller amount? Thank you in advance for your help.
