I'm thinking about creating own gambling site. Do I need license for that? Does anyone have experience in this field?
It actually depends on the country that you want to start or build you gambling site.
But for most of the countries they do not require a license for you to build you own gambling site, as long as you are paying the taxes that should be paid by it.
and another thing, most sites now are a ponzi sites or scams and do you think they do have a permit or license to operate.
so far as I know, If you live in United Kingdom you do need a license to operate your website, for for others I don't know.
