You charge the players 1.98%, give 0.50% to players who bet 0.1 BTC per bet or more, and another 0.48% to the people who spam the forum with invite codes.  That leaves 1.00% for the house, the same as the other dice sites.  So if 1% is dangerous, it's dangerous for you too.

Then you keep 80% of that 1% house edge for yourself (only 20% of shares were sold at IPO), and give 20% of it to the investors (of which well over 50% is also yourself).  So the players get charged almost 2% house edge, and the investors get less than 0.1% house edge?

Seems like both sides are getting fucked, and only you and the spammers are winning?

Or maybe I've misunderstood something.
