Well, I had an experience when I made a deposit and nothing happened, here's the point of online you take all the risks. The most unpleasant thing is that you can still be blocked by everything.
you did not even clear what you are saying here , you made a deposit then? what do you mean nothing happened? have you tried withdrawing and got nothing ? are you being blocked?
maybe you have something done wrong and that is the reason why?
because only scam site that will act as you mentioned , those legit will not bother taking your money as long as you are not abusing their site.
