I thought .org cannot be used for gambling website because so far, I see .org is only used for the organization or something like that. I hope the OP knows what he did so he doesn't break anything. But I see the site have a license from Curacao so maybe that will be fine to run the gambling games on that site. I think he can search the other type of investment and why not he invest in bitcoin, which could give him a profit in a long-time than to invest in the gambling website?
Yes, .org domain extension is just for a non-profit organization, so if you use it for a gambling website, I think it will raise a red flag in terms on the credibility of the website.
