From all of his strategy, he can wins some but he must know and realize that he don't have to spends too much money just to make sure his strategy works. He must realize that the strategy will not always works in the next rounds so he should not trying other strategies but needs to take a rest for a while. Having much strategies is good but he must know how to use his money to test the strategies. He can not risk more money but he should stick to his limitation to avoids the big lost that may happen. Players indeed needs to be smarter to realize the situation and not just chasing the wins by using his strategies.
It is true what you said, indeed with the current many people who gamble they tend to look for and have their own strategies to get victory in the gambling they do, but the thing to note is as you said by not having to spend a lot of money just to try the strategy they have or have just found, because usually when they fail to get victory with their strategy they will look for a new strategy, this is not recommended but most likely many people are like this.
I myself think there is no powerful and accurate strategy to make victory easy to get, but what I set is my behavioral strategy in gambling which must have limits in gambling. that's what I pay attention to.
