Signing your message is cute, but it gives no authenticity to your claims. 
You say Satoshi have no access to his private keys, so it will be impossible for him to prove that he is Satoshi Nakamoto... right. 
Why would Satoshi reach out to you? Why would he suddenly want to come forward to take recognition for his work on Bitcoin, if he went into hiding for nearly 10 years?
Curious to know why you are doing this.

If people would plan to tell something then he might give out some charge of it? What you think the possibility?
I do rather see this stuff as a shady act because its impossible for Satoshi to forget his keys.If someone doesn't prove
anything will always be a faketoshi on everyones eyes.
