No, I do not have the experience to play on the site you mention because I can play in another reputable gambling site that I know will not scam me.
You can play at many gambling sites as you want but you should remember that not many of them will not try to get your money by closing your account without asking you.
Playing gambling has a risk, so you should know that you do not have to use those 5 BTC just to play gambling.
Once you deposit too big money, the casino will watch you and continuously monitor your activity on their site and will do something if you do something suspicious and tend to cheat them.
