From my personal experience, GDN has remained stable and active more so then other coin communities I have worked with in the past.

Often, I see a new cryptocoin start up and it appears very profitable at first. This is simple supply and demand forces, because there are very few coins available in the market, and so there are more buyers than sellers in the beginning. This causes the price to spike very early on. Then after the surge in price, miners start hitting it very hard as it becomes easy to mine and sell in the same day and turn a good profit. As this continues to happen, more and more coins enter the market. Eventually there are so many more miners and sellers that the price can longer be supported and it falls until it reaches a maintainable baseline. What happens after the coin has hit its stable baseline, is what determines the fate of most cryptocoins.

At this point, most crap coins would experience a dev leaving or lack of continued support and communication. This is because the dev doesn't see enough money for himself/herself anymore. However, unlike like these crap coins, the GDN dev's are still here. They are communicating, supporting, and actively developing GDN at a rate they can continue at in the long run. That is why I choose to invest my money into Global Denomination.

Just my two cents.
