I'm really liking the approach taken by this project on a deflationary ecosystem that has many potential use cases and a full road-map (the other projects that have deflationary tokens seem to ignore use-cases and future of the project).
Only recently came across pyro and still reading up on it but it's definitely a worthwhile experiment (supply gradually reduces to 10m fixed supply through burning a % of each transaction). Discord is very active with lots of people playing games, tipping and doing giveaways. Looking forward to see where this goes, if they can build upon the Apollo protocol/ecosystem idea with social network, messenger (already released on android) and the other planned features, a hard fixed supply token with many use cases that bolster network effect can do very well.
The airdrop and dPoS aspects ensure that the supply is distributed well and there is a fair chance for everyone to get involved.
