Guldens ranking goes down when btc goes up and today it goes down when btc goes down. I believe the coin has hit it's peak for the next few months. Won't post again until next year as this coin is a dead fish.
Talk to you next year
April, 08 2014: 0.000400 USD
April, 08 2015: 0.001144 USD
April, 08 2016: 0.002084 USD
April, 08 2017: 0.030600 USD
Only reason for the increase is the rise of BTC, not Gulden. If you had bought $ 1000 worth of BTC on April 8 2017 you'd be sitting on 0.85 BTC now, worth over $ 5,500. The same investment in Gulden would be worth $ 2,612 now, that's less than half!!
Conclusion?
NO Gulden is a bad investment,
stick to BTC!
