I'm not really much of a competitive person, I think it's great for the industry when there's more fair and honest gambling options.
Slightly off topic. But it also goes into why I think their house-edge is totally reasonable:
When someone goes to a casino, their intention is to gamble. If they win, they'll probably just gamble more. That's why I don't think from a business perspective an online casino will see a huge difference in revenue between having a 0.2% house edge and a 1% house edge (other than you can't offer as big limits sanely) as I suspect on a 0.2% edge site (e.g. like bustabit's historical average) people will tend to gamble ~5x as much as a 1% edge site (as people tend to be loss constrained).
But a site like chipmixer, I think the draw is clearly for privacy/mixing and gambling is just an add-on to improve that. So I suspect there's not going to be much turnover of the same money (if you win, you'll probably just withdraw immediately), so to sanely be able to offer it -- it makes sense to have a higher house edge.
For reference, for every 1 BTC someone's deposited at bustabit they've on averaged turned it over 18.78 times and then left with 0.96 BTC. Without such a high turn over, there's no real way I could really be paying the bills with such a low edge.
Anyway, I think what chipmixer is doing is pretty cool. I really like their idea of giving you a private key (instead of sending you money) so you can spend link it with your wallet and throw off any analytics. It's all pretty neat
