This website is a 100% scam stay away from it. I got through the survey after I tried to withdraw money from my account they locked it and said I had to deposit $30 in my account and wagger 60X to be able to withdraw.
STAY AWAY FROM THIS SITE!!!
I did not do any survey, but I believe there are some term and conditions that govern such bonuses to avoid cheats, no?
I have got and won bonuses from some casino before which I won't mention names here, but they do always have some wagering requirements and some even require you to make a deposit too before you can withdraw your winnings.
