The real Satoshi could just send a message saying he is not Craig.
This actually might happen the more I think about it. If Craig is not the real Satoshi, then the real Satoshi might want to dispel these rumors before it goes too far.
"They" say the real Satoshi died in 2013.
Who is Satoshi? He is supposed to be Turkish. Some say his father was German. Nobody believed he was real. Nobody ever saw him or knew anybody that ever worked directly for him, but to hear Gavin tell it, anybody could have worked for Satoshi. You never knew. That was his power.
