I feel like all these strategies have been tested and have been used for a long time to the point where gambling sites have made systems to counter them, i have been trying strategies in many different betting sites and every time it seems like it is going so well, i start losing not once or twice but 10 times in a row even if the wining chances are like 80% or 90%, i don't know if there is some certain sites where these strategies are fail proof, but if so then i would like to know where i can use them because some people in here seem to have some success with it.
