Your statement indicates that you don't know what a pyramid scheme is, or that you do and you're expanding its definition to generalize its negative connotation to something else that doesn't fall under the proper definition of a pyramid scheme.

A company using credit card technology in combination with bitcoin and other cryptocurrencies is simply leveraging existing technology interfaces for companies that want to accept cryptocurrency without said companies having to deal with alternative payment systems. The payment system handles everything related to the cryptocurrency and the payee simply sees the USD (or other fiat currency) value in their accounts.

I will stick to the pretty basic definition that a pyramid scheme cannot sustain itself when less foreign currency enter the system. That is because the system is blatantly unable to produce value and only produce virtual currency from foreign currency.

I stil don't see any argument, just as-hominem as usual when defending bitcoin: "Pheeww you know nothing...".
