If I won the first round and it doubles my money on my hand, I will just take the half of it to circulate again in the gambling and the half will be keep as it is nowt my profit on my gambling budget.
I guess it is not that bad to be wise, since I can keep my money that a lotted to gambling so in time I can play again in some other round.
this is what i am doing too when i am playing dice games because i don't want to loss my profit but sometimes when i play with the first money, i am not luck and loss that money. in the other times, i can make double the money again so i think still get profit although it is not big as the others.
