In a ponzi scheme the people higher in the pyramid are anyone who joined in the past and is trying to grow it. You could say Satoshi with his early mining and various other "insiders", whether their identity is known or not, are at the top. I don't necessarily agree that it's a ponzi scheme, although I'm sympathetic with many anti-crypto arguments, but that's the reasoning if expect they'd use.
There is nothing special about crypto apart it being digital and new... Art, collectibles, real estate... Many things have been overvalued with basis that prices have always gone up and being paid by those acquiring them later...
