Step 1 - say that your "coin" is not centralized Step 2 - proceed to contradict yourself in the next sentence How the hell is a an obviously centralized system with 3 dozens of privileged entities is not centralized... Also it is not only oligarchy, but completely unaccountable shady oligarchy. Why people continue to "want" it is beyond understanding.
People still tell me with a straight face that the Cloud is decentralized too. I'm mature enough not to smack them, but not mature enough that I don't fantasize about it.
Unless they think having Cloud services being offered by a couple of giant companies rather than one is considered "decentralized".
