lol @ "scheduled bi-annual upgrades".  Sounds REAL decentralized.  It doesn't sound like something identical to having a central bank running things in practice, I swear!  But really, it's zero difference from bitcoin.  All craptocurrency are centralized, permissioned ledgers and garbage compared to physical metals.  The only form of "decentralization" these things have is just like any other psuedo open-source project like Firefox, the head Natzee controlling the github occasionally allows other people to work on them for free.  Woopty doo!  

Let's also pretend something that is constantly being arbitrarly changed by random people like Vitalik is even possible to be fungible in the first place.  It's not fungible even if you mix outputs.  Money is not supposed to ever randomly transform from one thing to another.  If it does, it's not money.  "Blockchain" is solely a system of tracking and control and absolutely nothing else.
