In the OP it say's: "A temporary PoS coin will be issued until the Novusphere blockchain is available."
Will this temporary PoS coin be exchange tradable or do we have to wait till the Novusphere blockchain is available? And how long will this take?
The temporary coins issued will be available on exchanges once we begin undergoing procedures to be listed. As for the development of the Novusphere blockchain. It's hard to say how long this will take but for the most part testing of it will be done publicly and well documented so you can ensure progress is being made. We will be emulating the decentralized use cases of atmos in Novusphere on the current Novus hosted gateway so that the temporary coins can also be used in ways other than simply trading.
Thanks.
