I saw also the same thing , I  placed my bet two times for 0.001btc but unfortunately lost both the bet .
But when I figured out then I found that there is not equally chances that I will make bet Then there was not equally chances of winning and losing bcz digits and alphabet are resulting into big numbers of combination that will lower down the prediction .
So I don't think it will be better for us , because it is not in our favour.
I would like to suggest to go with the sports betting games like Nitrogensporte.eu where we can found new new game ( https://goo.gl/YfghTY ) of concept to make gambling .
And also we can gambling at another sports betting site where we should have equal chances of the win and loss .
