What about you?
Honestly, I think a lot of people don't give a damn anymore about his face. Bitcoin has been able to sustain itself till this moment without his further input. I think it should remain that way. His sudden appearance will definitely shake the market, whether anyone admits it or not. There's going to be selling pressure if that happens. We're better off now without that revelation of the person of Satoshi.
I think so too, I don't think many people care about Satoshi's face or real identity anymore. Bitcoin has become so big, and all people care about is how to earn more bitcoins because everyone knows this is the way to get rich.
Many newbies entering the market today don't even bother to read the Bitcoin white paper, and they jump into bitcoin like moths into a flame to make money. They don't care and want to know what bitcoin was created for, so how will they care who created it?
Not as many people care about satoshi's identity as we think, so I think his appearance will probably cause panic in the market. But that won't be significant and long lasting.
