Of course I'm not asking to start discovering any exploits

But if you find a way of winning every time you play, it should be fun for both you and us. In other words, we didn't have experience of paying for bugs, but once again always glad if someone is sending us their feedback.
How are you going to do this? because you have state that you are not giving any bonus if someone find an exploit, that means why should people tell you if they find any exploit, they can just use it to win or steal someone's fund from the site. Just because you dont have experience in paying bugs that does not mean your website is very secure
