There is a problem about the license on this casino, the Antillephone NV 8048/JAZ has been used by many casinos in the past, and a lot of them end up as a scam, source: https://www.casinomeister.com/forums/threads/8048-jaz-license-can-someone-explain.57269/

And when we try to validate the domain with the Antillephone validator, it says the domain isn't valid.

I would recommend being extremely careful while dealing with this site, because when you send them your personal data on the KYC process you don't know who they are, and you will not be able to complain in the future with the license provider because they don't have a valid license.
