The big question is "Why isn't EVERY holder of BTC doing this"?
MOST don't know about this - of those that do...MANY are afraid it's bullshit..but those that BELIEVE it works are afraid Gox will suddenly go insolvent (it could) and they will get FUCKED. But one thing is certain, many risk takers are making $$$ off this right now.
