Mastercoin to rule them all.
Mastercoin is amateur hour compared to what these folks have planned.
Right. Ethereum is to Mastercoin what Peercoin is to Bitcoin. 1st mover advantage will be huge.
Also, Charles said at the Miami conference Ethereum will only be traded on the open market Q3 or Q4 (autumn-winter of 2014) so those buying into this IPO for a quick flip have no idea what they're getting into and will be locked in from trading for quite a while.
Ethereum, Mastercoin, Open Transactions, even Ripple are going to partner or work closely to build inter-functionality. The community is becoming more cooperative than competitive. There will be quite a few winners.
Did you watch that video? Got to love the tension there between Charles and the Invictus dude. Just watch Charles' reactions when Invictus dude talks. It's clear as daylight they have eachother's guts. And they've put the MSC guy between them to separate the two. https://www.youtube.com/watch?v=w-9miCOsg4g#t=1541
Also notice that "touring complete" part", when Charles gets pissed at the Invictus dude talking about Turing complete as being part of his project also.
These guys hate each other, make no mistake about it. They were just playing nice for the camera. You're naive if you believe otherwise. They were just playing into the narrative, that's all.
