While I do agree Poloniex would give a 1000% boost to Gulden , It will be short term affair and people will be expected to buy Gulden at much higher prices. This wouldn't be fair on new people.
The advantage of Gulden having such a low price compared to other coins on Poloniex is that more people get to experience more natural growth.
That's your pro. Here's the con: NLG is trying to peg to fiat (a good strategy which I and others pointed out to devs) but unless there is a significant support at some psychological level, say 0.1 EUR or (better) 0.5 EUR, the general public won't take it seriously.
There is one thing you keep forgetting. Gulden doesn't focus on crypto-users. We focus on the REAL general public. Honestly, we'll take our time and will grow slow but steady. Don't forget that a lot of European people like to save money, with POW2 the interest rate is a lot of higher than that of a bank. Soon services to help with saving money and getting interest with Gulden will pop-up, for those people that can´t install an Pi3 themselves.
