Gulden was in Top 20 once 
Yes, that was before all ICO's comming in. If you remove all scam tokens, Ico's and non-minable coins it is stil in top 20-30.They should of split the PoW2 and SegSig development, adding SegSig cost them time and this is why the coin is not in the top 100. Both innovative projects could of had it's own release schedule and a lot more attention. SegSig has caused the main developer delays and we knew it would because the bitcoin developers only managed 25% savings. Gulden is going for 58% savings and if the dev gets it right the coin will be top 10 (My prediction) or it will remain in testing with bug after bug until they give up.
