Yeah, this is the thing that made me realize that cryptocurrency is pretty much always a bad investment.
Stocks aren't zero sum, at least in their idealized form; if I buy a share of some company, they can use that investment to create products or provide value in some form, and if the product is good then that gets reflected in the stock price increasing. It creates value, and the stock price follows.
With cryptocurrency (with maybe the exception of the more computation based stuff like Ethereum?), it doesn't really do anything, it's not creating value. It's just transferring between wallets, and the value increase is pretty much entirely speculative.
Obviously not all stocks are "ideal" like I mentioned above; there have been plenty of cases where stocks are ponzi-adjacent, and it's certainly not uncommon for stocks to be overvalued during bubbles and the like, but my point is that stocks aren't inherently zero-sum like cryptocurrency is.
So, to see if cryptocurrency is a pyramid or not, just look at how much is transacted compared to its total value...
Or don't, because you already know the result. But it's not inconceivable for a cryptocurrency to create value. It's just that nobody did one that does it yet, and the culture around them makes it less and less likely as time passes.
I don't think cryptocurrency in its current state could realistically work as currency though, because it's deflationary in nature. For the same reason we don't use gold or silver as currency anymore.
