Every people try to win more money when the person is in profit and those who are in try to recover the money which the person has already lost. And it may make more loser so I do not think we should play more while we are in losing mode and/or earn good amount of money.
One thing that it isn’t realized more often then most is that, gambling is a profit based business. The pay for the wins has got to come from somewhere, for game offerings, registrations, developers and more. These they hope to get from loses and so, someone has got to lose for the business to continue.
That’s why as a gambler, you should be open to loses because, that’s as much part of the gamble and a side to every bet. You don’t expect the house to lose more often, you are at that end.
