I just don't exactly know if there's something renting business license for gambling, if there is probably it's an illegal to start with (correct me if I'm wrong though).
I'm not an expert,but here's my 2 cents.
Most crypto casinos have gambling licenses from Curacao,but they operate globally and have customers from all around the world.I don't think that those crypto casinos are based in Curacao,their owners,developers and employees aren't from Curacao for sure.The servers of those crypto casinos most likely aren't located in Curacao as well.They just buy a gambling license from Curacao,because it's cheaper and easier to get and
there are less restrictions in the license.
Basically renting and/or selling a gambling license should be considered illegal,but I'm not aware of the gambling regulations in offshore jurisdictions like Curacao or Malta.
21,900 EUR per year + 6% sales tax. The renewal of the license is priced at €21,900 per year + 6% sales tax. . However, for that price, you will will get at least:
Professional consultation
The gaming licence itself
Control over complying with licensing requirements
Two domains and one validator
