Some very good points to be wary of! I hope you're wrong of course. Alas I agree it's always good to question EVERYTHING. The identity of Nakamoto is truly a question of great importance.
I have recently stumbled on Bitshares, the 'parent' cryptocurrency of Steem runs on, which operates a Decentralized Exchange. Anyone can make an account\accounts. Recently people thought it was strange that Bittrex(a popular exchange with KYC) is deleting Bitshares from their exchange. Apparently they claimed 'unfixable vulnerability in Bitshares Code, vulnerability to 51% attack' or something along the lines of that. But if that is true or not I'm not sure. Of course it's never good to put all your eggs in one basked and 'if it's too good to be true' often it is. So many factors to be aware of while 'playing the crypto game.' Many might scoff but there's some red flags like you said. I'll check out your links later...
Recently Snowden tweeted

Agree. Zcash's privacy tech makes it the most interesting Bitcoin alternative. Bitcoin is great, but "if it's not private, it's not safe." https://t.co/HqwQOvSCiz

And one thing about Snowden... I never for a second think he's lying or that we're not 'spyed' upon... but since his 'revelations' were put out even on CNN and whatnot, I have to wonder if those revelations he made are like another form of control... like people won't want to speak up if they think 'big brother' is watching them. Anyways! God writing and thanks always for the posts. Keep it up.
