gulden coin is not good investment
because not big gulden coin user community, and not big volume transaction , is bigerst volume transaction only 16 bitcoin/24 hour
so is very dificult can take profit if volume transaction is low
Well, Gulden (NLG) is made for paying with ease ,made for normal ,working and clever people .For shure it is not made for you, coin hoppers and profit takers with P&D agenda.
Gulden have a huge community.And all those Gulden's are nicely spread between people and not between some people like you who cares only for a quick buck.Go search about it and if you are clever enough you will go and colect those Guldens as much as you can.
