Bitcoin fails #1 because it is not run by an individual or an organization.
Satoshi no individual?
Satoshi doesn't run anything. He described how it could work and publicly released the source code for the first software implementation of the concept. Anyone can do anything they want with that source code, and it has been modified by many people. It is entirely available to the public, and Satoshi has no control over it any longer.
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?
I wouldn't even try to guess why the person or organization known as Satoshi has chosen to remain anonymous. It really shouldn't matter since all they did is describe a concept.
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.
If everyone stops mining, then transactions will stop being confirmed. Of course, that will make it very profitable for someone to start mining again since they will get all the blocks and all the transaction fees. Then others will start mining too because they will see the opportunity to get some of that profit. What makes you think everyone would ever stop all mining?
