This project is going nowhere. And so is Ripple.
Yeah. As for Ripple, I have heard that it is centralized in which they control the supply, etc. I don't know if Stellar is the same, but if it does, it will be going nowhere. Many things needs to be implemented into Stellar like a GUI wallet, a mobile wallet (Android/iOS), and perhaps a decentralized exchange for it (like BTS has). Just my opinion
STR is also a premined centralised coin
I find that mining is a massive waste of energy (that could be put to better use).
