this is not just about a ponzi scheme or an empty pyramid without end users. Bitcoin still has end users, because basically end users are still in the consumption section (food, clothing, etc.) if you only see money as a reasonable cycle for a transaction. I will try to sort it. Money ----> Goods / services -----> consumers (end users. Bitcoin is quite simple, BITCOIN ----> MONEY ----> SERVICES / GOODS ----> CONSUMERS. This is the same , no difference.
