For me as long as the strategy that I use still works, I won't stop using it. I am afraid that if I switch on the other, the winning momentum that I am feeling with is going stop but I admit that I was once a paranoid when it comes to gambling that I think the casino watches every move that I make. That is why I keep on switching my strategy.
I think you don't need to be paranoid about the betting strategies that you usually use in gambling, so as long as you don't violate the TOS then every gambler is free to carry out their own strategy to gain profit, but is it possible for gambling platforms to track betting strategies used by gamblers from betting history! I don't think so because the team has to keep records of every winning history from the gambler's account.
