Say i make a website, a website where you can deposit "virtual" currency, as in credits from an RPG or any other game that allows ingame trading with other players. after a deposit, players are awarded a certain amount of "credits". The players can use those credits to gamble on the website. When a player is done gambling, he/she can cash out the site "credits" back to the currency of the game he used for his deposit.
The cashin/cashout process will be done by manual 1 on 1 in the game of choice. The website will only do cashin/cashouts with virtual game currency, and will not allow any direct way to convert your curreny/credits to real cash.
the virtual currency could have a real money value on the game's black market (unofficial, not sold or bought by the game devs, usually against the game's terms of service), but the website won't have any direct ties to that.
does anyone know if a gambling license is required for a website like this?
