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.
The Curacao license is the most popular because it has a much easier requirements and very convenient to get in able for your casino legally operate on many countries that there license is valid. Curacao is one of the early license provider on crypto gambling business that’s why it was the best choice for crypto casino. There’s other license provider but they have a very limited country scope which is not practical at all.
Curacao KYC is now adjusting based on the casino country origin.
