the question is how effectively in a positive or in a good way will you use that money or play it again to try some profit again.
I am sure no one can be finding themselves into positive side if they keep on adding their profits into bankroll for gambling further. Because there will be no guarantee that gambling will remain profitable in longer run. But in my experiences, whenever I gamble for short I will be getting chances to stay with profits.
To stay in positive side of gambling profitability, we must stay away from gambling
or at least we must gamble for limited time and for limited bankroll.
