Not sure what your "p/s" vs "p/e" distinction is, though?
If you calculate your share (1.9%) straight from the bets, that's what you get in, ie. revenue (or "sales" in Price/Sales ratio). You have to deduct any expenses you have from that number to get your profit (or "earnings" in Price/Earnings ratio).
Your expenses per day are 4.68 BTC thus your avg. expected profit per day is 99.69 BTC - 4.68 BTC = 95.01 BTC. Same thing with monthly/yearly figures.
Your investors will not receive your revenue, but profits, ie. net income where your expenses have been taken into account. That's why P/E is used in valuation, not P/S. Like dooglus said:
The performance of the site is certainly very impressive, but it would be better to have your statistics be correct too. There's no need to exaggerate them.
