You are getting agitated because you are not able to handle the truth. The truth is that Bitcoin *is* a Ponzi scheme. At-least until now.
People who get in early and HODL will make way more money than those who come in later and HODL and so on and so forth.
Right now Bitcoin is valued at $47k. The only way it will shoot up in price is if more and more people get into crypto and buy more and more of Bitcoin. This includes institutional investors, Billionaires, regular people, people who switch from Alts to BTC etc.
If nobody ever buys another BTC, the price will collapse because most people (99.999%) who "invest" in BTC/Crypto are only doing so to make more money.

Your are one of the ignorant people I mentioned before. You say that Bitcoin is a Ponzi scheme, but you don't know what a Ponzi scheme is.
You go on and talk about pyramid schemes, as if you believe that a pyramid scheme is a type of Ponzi scheme. That demonstrates that you don't know what a Ponzi scheme is.
