Income
BetterBets.io casino has earned at the time of this post 171.91BTC in income since launching on May 19th, of 2015. With a good team this casino could easily maintain a top 3 position in the market. It's been in the #2 most volume sites multiple times.
That 171.91 is revenue as in gross income, right? AFAIK you have a pretty aggressive rake back program which I believe is not included in that figure. In order to maintain the current volume I think the rake is an important factor. But how much is your net income after considering rake back and other expenses?
