It seems like a joke, but its real.
I give you a proof when i have the money.
Best regards!
Just post the btc address already, that should be enough for them to see how it goes later.We will be able to check whether you have actually send the money from that address to another.
The story of Craig having the private key of Satoshi's address isn't something people ill easily believe until he can sent even just one satoshi to another. Fake signature sign isn't the solution, its how much you can actually send. If you can send them all and if possible give some pennies to your audience here will be worth their time.
