My impression was that this was the main "value proposition" of the Gulden: to seduce nostaligics into it, as there are quite a bit of them. But it may be that the Gulden has also really something to offer, apart from sentiment ; I don't know. But I would be seriously wary about the fact that the name has been chosen to play on a sentimental chord.
Do you know there is a book out there that list all the currencies that have existed since a certain point in history (is does count a long way back, centuries). The dutch Gulden was actually the one currency that didn't fell in 2000 years, but we gave it away for Euro. Gulden was longest existing currency that didn't go boom and lasted hundreds of years. We will rise again
But that is exactly what I wanted to say: it is a name-trick. The crypto currency "gulden" has NOTHING to do with the Dutch Gulden, apart from that name. If you would have called it "crypto789" then it wouldn't exist. It exists because of the name, and that's essentially it. That was my point.
It is exactly because of the strong rooting of the Gulden in Dutch history that it plays on the sensible nostalgic strings of many a Dutchman (and woman) with this name, and that if it were called crypto789, it would not even exist. The crypto Gulden has simply nothing to do with the historical Dutch Gulden.
In the same way I could make a coin which is called DeutchMarkcoin or something, or I could call it Luthercoin or Calvincoin or whatever, to play on an emotional string. It wouldn't even have to have a block chain, just IOU tokens on an exchange.
