I don't know most of those projects but from what i've seen there are very few serious dev teams in cryptocurrencies.  Bitcoin is one, Ethereum is another, although neither is in our market (macro payments / programmable transaction contracts).  

Our market is user's who want digital cash; money you can spend online/instore from any device without an intermediary. Implicit to that is users not having to wait or identify themselves if they don't want to which we have already and also not having to learn anything weird or go outside their comfort zone (easy to use).  

The goal sounds simple but there is a lot needed behind that and I haven't seen anything even trying yet (anything p2p that is...there are lots of currencies sending coins through some guys server and calling it decentralized or private but these obviously don't wash with mainstream users who are sticking with much better equivalents like PayPal/Google/Apple pay/Visa that are more convenient to use)

I would be interested if any other projects are aiming for our market too, if they are serious we could work together or learn / help each other. But I haven't seen any, apart from some awesome Bitcoin ecosystem innovators who's work has become really valuable for us to build on, but they're all stuck in Bitcoin, who's current dev team will never make the changes necessary to achieve a decentralized ecosystem and really let crypto take off - ours does though
