Where can I buy Nest protocol?

Could you please tell me where I can purchase Nest protocol? I've been hearing a lot about it lately and am interested in adding it to my portfolio. I've tried searching for it on popular cryptocurrency exchanges, but I haven't been able to find it. Is there a specific exchange that supports Nest protocol, or is there another way to acquire it? Additionally, are there any risks or considerations I should be aware of before making a purchase? I appreciate your help and any guidance you can provide.
