I really don't know what guldencoin stands for. A social experiment? A political one?
From who they want to break for? From euro? I really don't understand why it's needed in the first place.
As for auroracoin I wish that will always be perceived as a mechanism for „breaking the shackles of fiat currency”. With no politics involved. Nothing more than something like a natural force. A string of bits, carrying around value in a secured way.
