I have some questions.

Since it's stated that when you ran out of bankroll you cannot participate anymore, I think that is given since you can't bet without a bankroll. 

Based on my understanding, we just have to share a screenshot of our bet, if a bet win that's +5%, if it lose that's -5%.. very simple I think.
I would like to ask also what is the minimum odds for a bet to qualify? 

And last but not the least.. can I share my bet as many as possible in a given day?

Did I get it right? if not, please point my mistake.
