Hi! I don't know much about it so I want to be sure before I start. Do I need any licenses, paper work, or something else to start poker multiplayer site? IF players don't use real money. I will not sell this virtual money for real money. And the only way how I will earn with site will be some affiliates (betway for example) Is there anything else I should know, before I start?
you will need license if you offer a $$$$ reward to the winners or players who have more virtual money
And what If I don't offer rewards or real money? And as I said revenue will be only from affiliates and banners Then I don't have to worry about legal issues?
You wouldn't need any licenses if it is just a affiliate site. The only way you would need a license is if you accepted Real money in exchange for chips yourself.
