What if no one knows you're actually scamming them?
I don't want to be rude... But the majority of the people playing on casinos thinks that since there's something encrypted, then it's provably fair and won't try to look at if it's true or not by the simple fact that they don't understand a single thing about this.

Since your site is not provably fair and has been proven by many people already, I'm surprised that you didn't yet fixed it.
...
Probably because you don't know how. (That would be legit, no one can know everything... learning isn't a sin and no one would blame you, in fact I could help you fixing your game)
or
Probably you don't want to. (That would just mean you like to be able to rig the game times by times and get money from those players who don't understand what's really going on)
