Re: Craig W. only claims to be Satoshi, because he knows the real Satoshi is dead?
Just an idea. If Craig Wright is NOT Satoshi Nakamoto, he would definitely risk the real Satoshi come up with a proof, that Craig is not SN. Is it possible, that CW explicitly knows about the death of the person behind SN, so he can make his claims without backing them up with a proof? 
Yes, this is a very common theory, and given the personality of Wright, who clearly knows something about the birth of Bitcoin, but cannot provide any significant evidence, this theory is very, very strong.Although I have been telling everyone since 2015 that Satoshi is probably unfortunately no longer with us.
