bitcoinbev made me rich to, but im still waiting for my 1000 btc to be paid.
First of all this website will not pay you anything, at least im still waiting for mine, so I doubt OP.
Second, the "3D roulette" runs on javascript which is client side, so it can be easily exploited.
POC:
CGame.js:317-363
this._generateWinLoss = function(){
...
var iRand = Math.floor(Math.random() * (38));
...
return _iNumberExtracted;
Exploited CGame.js:363
return 7; //ma lucky number
Inject the new CGame.js and delete the old one from the site (using chrome).
