On my working hypothesis, the smart coins are buying, and the dumb coins are instant selling.
on my hypothesis the smart coins are not even using mtgox and the dumb coins are being deposited and trading on mtgox
You got me there, smart and dumb being relative things. I'm a dumb noob with 2 BTC stuck on gox, waiting for this weirdness to play out.
Although I might hold to my hypothesis that there are indeed some very smart coins trading on Mt. Gox. And making bitcoin bank.
