Qora is interesting, it's repeating the path NXT followed, but on a smaller scale. Should NXT fail because of a fatal flaw, Qora could be one of PoS backup cryptos, as well as NEM and Bitshares. These three will compete for 'Litecoin' status of the PoS world.
I stared this thread to buy cheap Qora. I bought over 30m under 30 sats!
You're dead wrong about Qora being a backup to NXT. Firstly it's very very likely that Qora is BCNext on his next project. Plus Qora is better than NXT. The address is system is more secure, the wallet is far more user friendly and we will soon see how great it is in two weeks when AE is finished. It will take the developer two weeks to implement. That's about 5 times quicker than NXT with many developers. People so far are alsleep to Qora which is cool by me as I'm more concerned with accumulating.
Qora is not based on NXT, NEM is nothing more than a hyped re-write of NXT. Qora is better than NXT, the best always rises in the end, you'll see. FYI Qora project was started before NXT was released.
