Gulden is interesting project but its not true time to investing. At this time, buying bitcoin is the best investment.
Gulden need more time to increase

Bitcoin is not the best "investment" this moment... people are blinded by greed (Warren Buffet has a nice quote regarding that). They don't see the risks involved with the upcoming fork. It also became clear to me last week that someone bought a few BTC futures for 1000USD (betting on one main chain) that people don't understand how that fork will work. In that view NLG has been a safe store of value (being stable between 0.09 and 0.11USD for months).
