Stox or Augur prediction market

Hello Steemit!

I would like to discuss the differences between these two prediction platforms:

• Stox seems to have a more logical value proposition of their token, as it is the only one that can be used in the prediction. It is built on top of Bancor, although I do not really know what this implies.

• Augur has already a working platform whereas stox is still in the whitepaper stage. Less clear what the value proposition is since ETH/BTC can be used to do the prediction.

• Gnosis, way too centralised for me so not really interested.

Share your thoughts on these please!
