they claim there's a casino game they know so much and could provide signals when you should play those games and they do assure their followers of almost 99% accuracy such that if you follow their signals you get to win at least 9 out of every 10 and sometimes you get to win literally all the signals.
They want people to register under their affiliate link and get addicted, so they could earn passive income at your expense. If they can win 9/10 times, I don't think they would even bother trying to help anyone else. Not worth the time and effort. Just think about it. Why would they go through the effort of convincing someone online and then trust them in giving a share of funds if won? chances are extremely low.
