No, I haven't looked into Cindicator. How far is it into development? If it's not launched yet like Augur, there is yet another option out there which is even smaller - Gnosis. Of course, the reason why is because circulating supply is so much smaller than total supply, so Cindicator might still better.
It's probably better to have fewer questions like Cindicator seems to be doing (based on what you told me) than the scattershot approach Augur is taking where anyone can post them, given both will struggle with adoption. If you don't have a ton of users, the best you can do is concentrate them by having fewer prediction markets.
How is consensus reached on the outcome of an event? Same as Augur or differently? Anyway, maybe I'll look into it at some point. One point I want to say here is that all of these "prediction markets" are fancy gambling platforms, so can be good to look at other gam-ahem prediction markets that exist out there. Thanks for your comment.
