If you had the brains and did your research, most popular sites can prove they are "provably fair". What site are you talking about? Stop rage posting, and start with some evidence. 
Not only that, but this feels like another degen gambler rant. Ever notice they always seem to have a problem with the fact that they lost, and are trying to rationalize the very probabilistic outcome with some universal evil, or someone out to get them? "These casinos are scammers" or "not provably fair, rigged!" always says much more about the person than about the casino they are playing at.Just because it's a rare event doesn't mean it can't happen, and sometimes, you get unlucky. Too bad, OP.
