Does the development team have timeframe for Prime? I think this is what people want before they invest in Gulden, some of my circle in Germany say Gulden has not done anything different to bitcoin and want to see the development team is capable of doing evolutionary progress and not copy others.
Gulden developers have done DELTA, the most advanced diff algorithm. Most coins move off scrypt or went full PoS but Gulden took the hard route and stuck with scrypt and made it work.
