This coin is based on the old Dutch currency that existed before the euro.
I myself am both Dutch as well as a crypto-investor. I would not touch this crypto with a ten foot pole. I have no idea why it has spiked in value, the only explanation I can think of is that influential parties made a bunch of money with trading other crypto and put those profits into Gulden in order to create a buzz and possibly reach (Dutch) newspapers because of the crypto hype.
I see no chance in this coin ever becoming adopted by citizens of the Netherlands.
