Definitely you are going to make profit but I think it depends on the period or will I say the time you will make this approach because there are periods you will try this... And trust me you won't see any reasonable profit because the loss will be much and there are also period you try... You will see much profit so that is how it is and it will be wrong to use a period to justify the whole because that will be wrong and not correct. But me personally I don't too fancy this betting after game have already started It doesn't give me the vibe I want.
The gambling industry will give you luck,when you are potential enough with your strategy.Even though some game in the gambling was based on the luck.Some gamblers will money using the strategy for certain period of time.When your strategy meets the gambling algorithm,you will gain money from the gambling sites.The exit check was most important one in the gambling,you should exit the game after a certain amount as your profit.Personally you should be greedy and leads to complete loss in the gambling.
