no i dont think gulden is good for investment.
there are lots of good projects. we can research for that.
Any reason as to why you think it isn't a good project? I've been following it for some time now and a long time it was hovering around 0.07 - 0.10 but it seems the project attracted a lot of new people and the price is going up quickly.
