Is this the original dev for this coin or was it taken over at some point? Also, is Styx a rebranding, or are Viacoins going to be burned in order to get Styx? Or is this gonna be a thing where depending upon how many Via you hold that's how many Styx you'll get?
I think you are confused. Styx is the name for the anonymous implementation for Viacoin.
Viacoin is here to stay.
