That aussie was just trying to jump into his dead friend's shoes. Nothing to see here - move along now.
Do you believe Satoshi never disclosed his identity to his close family members too?
I dont think anyone with such a huge fortune has not make any arrangement to bequeath it to his heirsI assume David was raised Jewish by his parents who adopted him, thus, perhaps, whould've entrusted his closest family members to his estate oppose to a dude that he once penned some work with living down under.
