As a community, I do not think it is a pleasant group. As soon as you start a discussion and they are fed up, you will be banned and banned from their social media. Compared with other projects, you still have the chance to find out why you have been banned via other channels. But with Gulden there is no way. This makes it less reliable for me.

And as a final argument. Why would you only want to develop a currency for 1 country in the time of Crypto? There are so many possibilities with Blockchain in general. Should a currency be developed for the world in the future, it will quickly take over the place as a global currency. What kind of chances does Gulden still have?

So my opinion about whether it is a good investment. I would personally look further at other projects and put my money into it

We need relaunch this coin, I hope someone able to  take the project to the moon.
