I'm sceptic about this. just another marketplace which's comparison against other marketplaces is not really fair.
Fiverr for example offers long term projects with custom offers. Multiple points look nearly the same(student.., student.., student..). Also the comparison doesn't contain all the marketplaces continuously to the end instead it switches somehow in the mid..

The anonymous concept looks fairly good so i'm still in after the crash.

I read they want to switch before November 2017. Before that, its an hybrid with every 100 blocks is "mined" with PoS.

The miners definetly will change to another Ethash Coin. Maybe it will push the trading of this coin but in general i would say it will dump the price as there is just more offers on the market with the same demand.
