I don't see Guldencoin on Poloniex
I don't see Guldencoin on Cryptsy
I don't see Guldencoin on Mintpal.
The other exchanges are all in bed with coin creators. The dev for paycoin(Deppj) gave Cryptsy a backhand to get on there. Paycoin has been dead for over 6 months and still on cryptsy.lol
For what it's worth, NLG has been on the new CryptoRush 2.0 for a while now, most volume @ bittrex though...
