It doesn't seem credible to me that the real Satoshi would have to gin up some fake evidence that he was Satoshi. If he wanted to leave a trail of bread crumbs, presumably he could have found some real evidence to leave behind. The whole thing smells more and more like a hoax.
Agreed. Maybe the dead American was Satoshi, the Aussie was more loosely involved, and is trying to pull a weekend at Bernie's.
It equally makes no sense that a man who has funds to assemble the Co1n machine with Tulip Trading would muck about with an elaborate hoax like this... It makes no sense in either direction.
