I think Cloudbet are licensed anyway, you can see it at the bottom of their homepage. I think they're licensed in Curacao? This probably means that they need to follow the requirements of the regulator which means including KYC in their process.
I would always choose a casino that performs KYC anyway, it means they don't cheat their players
I don't know too much about curacao licensing, but i do know that a lot of popular casinos are licensed there.
