0.009 or 0.01 a day because i am only a poor man haha...
A poor man should gamble nothing.
Depends on what a rich mean is like for you. 0.01BTC is a lot especially because you lose most of the time in the long run. If you'd calculate, it could mean 3.65BTC loss per year WITHOUT any other funds you're going to deposit. You better not play with that much if you say you're poor.
It's approximately 7 to 8$ per day. This is one decent money for the ordinary person. I think he is not poor but by losing daily 7 to 8$ he is becoming poor that's it. I have not fixed daily limit, but per in one full week if I lose more than 0.04 BTC i will stop my play. I will do sports betting lot so that I will get both profit and loss, if I lose my bet, i will get my loss in next bet. And I will play only how much I can afford.
