The perfect strategy exists
The answer is obvious NO !!!
But there are very good strategies, but for these strategies to work in your favor, there needs to be balance when you use it.
Many people think they will put in the autobet and leave it and get rich rsrs .....
Others think that it is only to have a good bank that will profit.
In fact neither case is security gains.
The only way to win with betting sites is to have a lot more patience and emotional balance, if the person does not have these two factors nothing she does will guarantee you profits in your strategies.
