with my experience as a gambler from more than one year, I can say, any one can win if he plays with good control over his emotions and greediness. We should take over all profits of a particular month. But not session wise.
Tup this will workout but for this we have to play safely and think lot about our betting. Not every one will control there emotions and greediness while playing gambling. Because our winning bet will change our greediness and loss will change our emotions so those who control there will power they can follow this method. If they follow this method really we can make some profit.
