International Gambling Bet System and Law ?

Hi there !

I wonder if any of you have experiences or usefull informations about International Gambling bet System and Law ?

1) By Gambling Bet System, i’m also talking about what are availables technics or scripting to do it.
A UE4 Game connected with his website.
Players can bet on the winner in game and be credited with virtual coins that also appear on the website.
Players that have converted virtual credits for exemple 1$ =100 Virtual Gold Coins are be able to add or remove real money.

2) About International Law how it works?
Or the fact that Real Money changed into virtual coins will allow bets ?
Or there is others technics ?

I’m asking this because i would like to add this system to my 2 projects


Thanks for you time !
