This is just bullshit. Winning depends on what type of player you are. Would you believe if I say that most successful players take very little risk? Yes. It's true. I know a player named Gekkebelg who lives in Germany but he is from the Netherlands. He has been abusing the casinos for a while but almost no casinos can expose him because of their security issue. If they reveal what tactics the player is following to abuse their sports betting, other users will follow the same patterns as well.
Some big casinos like Stake, and Sportsbet may not consider their actions as abusive because the amount is nothing to them. But when small casinos catch his tactics, he always creates scam accusations against them and ruins their reputation.
His simple tactic is, he watches the game and he places a bet when the result is obvious. He places bets on the lower odds and the winning side. 90 percent of his bets were made after the half time or when the game is going to end. As you may know, casinos have to update the odds every second. Because a simple goal is going to change the match result. He waits for the moment when a team scores and places a bet before the odds get changed again. Pretty dirty trick to be honest. Of course, I do not have any proof. But, I have seen his bet slips from the screenshots he shared. This is what value betting is.
