Please, no China conspiracy theories.
China is completely irrelevant here.
Are you saying that any transaction with (say) Bitcoin that's not a cryptographically-sound circle jerk requires at least one outside trust-based input?
FWIW, I saw on a very old thread that the first iteration of Mt. Gox (when Jeb McCaleb owned it) accepted deposits from PayPal.
I'm saying that Bitcoin operates out of a Nash equilibrium. This shows that words of r0ach ("There is no Nash equilibrium in such a system, thus it has zero value.") is a nonsense. Or Bitcoin has zero value.
PS: Btw,
The contribution of Nash in his 1951 article Non-Cooperative Games was to define a mixed-strategy Nash equilibrium for any game with a finite set of actions and prove that at least one (mixed-strategy) Nash equilibrium must exist in such a game.
This kinda shows that r0ach didn't put much thinking into that phrase. Probably it's indication that he doesn't understand what he is talking about. I'm not surprised, though.
