So my question is - How much winning is enough for you in a day. You're answer should be based on your capital not on your multiplier. Also how much is it for losing?
I do not limit my gambling activities based on the amount I win. There is no exact number, but when I get a multiplier that eventually provides a profit that doubles my capital, I will definitely end the game. Regarding how much I lose each day, I limit it to no more than $50, provided that I do not gamble every day for a full week. If I gamble every day, of course, the allocation would be smaller.
