Well that's sure a low HE. But there is a problem here: it's too low
Now don't get me wrong, it's not that I dislike it for sure no! But the problem here is that it doesn't change much for us to have a 1% HE or a 0.001% HE, while it means the world for you.
I'd advise you to put your HE to at least 0.5% so that you can get some profits and still being much lower than average HE and use the money to developp your site. That's more important
First: you don't expect to lose your money when you bet, otherwise you wouldn't bet at first
Second: the lost of 0.0001 or 0.01 doesn't make a huge difference for you but a huge one for the site.
It's more important to have a good site with original services than the lowest HE possible, at least for me.
You expect to lose money when you bet, or at least you should. You're fighting a house edge, which will always win in the long run. You always expect (whether you believe it or not) to lose X of your bet every time you bet, with X being the house edge percentage. Second, it does make a huge difference. If I wager 100 BTC with a 1% edge, I'm expected to lose 1 BTC. Compare that to 0.001BTC. Huge difference.
