remember before February 21, 2014, Evan already forked DASH from 84 Million supply to 18 Million..

clearly he is still not planning to tell the public about the masternodes in February 21, 2014 but since a guy asked him in reddit he was forced to speak about it....

I wasn't going to mention this recent speculation of mine, but since you mention that...

I had thought that I had pushed Evan to the masternode concept (our own egos get in the way of our objectivity, but I think I just wasn't that interested to research more and accepted the easiest assumption). Someone dug up my post from back during the beginning of the Darkcoin.

But based on what I read recently about some statements Evan made during the XCoin stage before Darkcoin (c.f. the link @arielbit provided upthread), I am now speculating that Evan knew exactly that CoinJoin would require the scheme Dash became. I am thinking Evan wasn't this bumbling half-smart, amiable programmer I took him to be (i.e. not quite idiot and not quite sophisticated is what I thought), and instead had already devised a masterplan and my post was what he was waiting for, so he immediately after that suddenly had the idea for masternodes to prevent the jamming issue with CoinJoin. I haven't really delved into the forensic evidence to try to build a strong case. I don't have time (nor mental energy) for that diversion.
