Bitcoin fails #1 because it is not run by an individual or an organization.
Satoshi no individual?
Bitcoin fails #2 because the non-existent operator of the scheme does not claim to earn a profit that is paid to investors.
Why do you think he's anonymous? Because of NO profit?
Bitcoin is not and can not be a Ponzi scheme. Anyone that says that Bitcoin is a Ponzi scheme either does not know how Bitcoin works or does not know what a Ponzi scheme is.
I think you obviously didn't know what i mean: Bitcoin is NO Ponzi now. Until everyone stops mining. I don't think that but who knows.
