I try to understand your logic of something having interest as being a Ponzi-scheme.

According to Wikipedia, ponzi scheme means only the early adopters get the benefit, while the laggards head off to lose. But my understanding of eMunie system is that everyone will get the benefits from interest, early adopters only get better interest when the network grows, but that doesn't hinder the laggards from gaining profits either.

And since there is no cap on how many EMu can be minted per year, nor total amount of EMU ever to exist, how can the late comers lose? if not out of their own stupidity?

On the other hand, Bitcoin, is definitely a true definition of ponzi-scheme, even it may lack some characteristics as pointed out by some economists.
