I think mastiff is currently overshadowed by a bunch of other coins who are promising the world, but aren't actually delivering anything. 
Mastiffcoin is promising things that it's fully capable of developing in the short-term, and they've delivered multiple times already. 
1. The flawless re-work of the specifications to ensure the blockchain continues to run fast and smooth as it did during PoW. 
2. The introduction and private alpha for the coin recycler that seems to have gone well.
That's only two bullet points, but it has only been a few weeks. It's a lot more "action" than most coins have made it a much longer time period.
