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?
Too much winning? There is no such thing. I would never consider any sum to be 'too much', unless we are speaking millions and more.
Losing is a different beast. There, I can and must have limits.
The thing is. In my opinion, for gambling it is very bad to be greedy but it is just as bad to be too humble. Extremely strategic plays do not work better than non strategic ones, luck is luck and when it hits you it simply does no matter how much or little you prepare for it.
