Bitcoin has been a good store of value but any shop I walk into that accepts bitcoin say they not getting any people buying using their bitcoin and who would since the value keeps going up and up. I think Rijk wants a stable price for Gulden so people don't have to fear that when they spend their Gulden the next day it's going to be worth 20% - 100% more. Then they can buy back in the next day at a similar value.
Merchants are noticing this about Gulden and why more merchants are adding Gulden as payment method.
It does suck for people who want to make huge profits but as a currency Gulden is performing better then bitcoin as it's more stable.
Marketing of Gulden sucks but with marketing would come more price fluctuations. I don't know anymore maybe Rijk has thought about this and why the marketing is non existent.
When you google gulden you get this: "Gulden - Added value for your money" I guess by added value they don't mean added value as in financial but as practicality. Though i'm sure 99% reads the first meaning
