It is really up to the person who is playing if he or she use his or her profit. But I do not urge on using the profit because that's my win. If I lose those I will go home without any money. But what I'm doing is if I already won I will go home. So winning something that exceeds my first money is equal to my house haha.
Yeah I agree but do not completely agree, we can think like that at this time but not necessarily can think like that while winning and according to my experience people will think there is no harm I try to use the profit because if lost I still have a chance to play with available remaining funds.
