I'm surprised that Sia (https://sia.tech/) has not been mentioned more often. Its high inflation rate and the high Bitcoin price are probably the reasons why the price for Sia was falling so much lately.

But nevertheless, Sia is one of the few coins that has a working technology today. It's the most advanced decentralized cloud storage platform out there. The software is running smoothly and the devs are working hard on improving the user experience and finding new customers and use cases. Minebox (https://minebox.io/) will be one of the first applications to use the Sia platform for their NAS boxes.

In my opinion, 2017 will be a good year for Sia. There will be a lot of growth and because its price is so low at the moment, a good investment.
