I have some top level domains (50+ domains) and am still using godaddy. And the godaddy's recent renewal prices are like 22-24 US dollars which is quite high. So I'm planning to transfer all my domains to cloudflare (yes I know DNS can not be changed which will not be a problem for me since I have dedicated hosting (static ip) and using cloudflare's DNS too) I guess the renewal prices there are cheaper in cloudflare. So I have two questions; 1) For the cloudflare users (for domain registration), are you happy with it? How much is the renewal fee? Would it be reasonable to transfer all my domains there? 2) If I have transferred all my domains to cloudflare and after some years I didn't like it, is it possible to transfer all my domains to another registrar like porkbun etc? Thanks in advance
