Fill me in? Which asset are you referring to? (inquiring minds and all that)
He ran the largest volume pirate pass-through (although it is disputed exactly how much of that volume was self trading). Bear in mind that PPTs were something like half to three quarters of
Global Scam Exchange volume at the time. He says he's satisfied/settled claims against him resulting from that out of pocket, nobody has so far come forth to claim different so prima facie that claim stands. That led to an usagi-style meltdown followed by a half year's vacation or so, which'd suggest he was pretty nearly wiped in the adventure (wouldn't be the only one with pirate, of course).
If you go through the
original S.DICE announcement you can see he's been spewing bs about it since roughly August. I'd say a case of personal investment, kinda hard to admit to being wrong etc. He does try his best to go about it underhandedly, creating knots of nonsense like "I'm bullish on BTC so that's why solid company A with a history and good management is no good whereas proven incompetence B is king & queen" which probably appear defensible to him - at least if one doesn't go looking past the surface.
Basically MPEx unapologetically ate a number of people's lunches. We did it publicly, insultingly and mercilessly. There be some sore butts left littering the landscape afterwards as you'd expect. His is one.
