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?
The truth of the fact is that when it comes to gambling, it's multiplier is far more important to gamblers than the capital been used itself. Because it's not all gamblers who has large capital and don't mind risking $1000 or more on just 2 odds to win $2000 and then stop for the day. Because the majority of gamblers who probably occupy 99% of the gambling population, what they always do is stake low with a huge odds, with the hope of getting lucky one day to hit the jackpot. Hence, when it comes to me, I will say that if eventually I'm able to get 10x to 50x of my stake each day, that will be totally okay by me, irrespective that as humans our needs are insatiable.
