A share of stock is a fraction of the cash flow of a company. A share represents a tangible thing which can valued according to any number of mechanisms.

Cryptocurrencies represent nothing but transactions and the ledger of those transactions (which they are exceedingly wasteful and clumsy at achieving).

You would be correct if the only thing that drove the price of a stock was current cash flows.

What you are leaving out is growth. Stock prices include expected growth of future profits which by no means is a science.

Not to mention all kinds of other things can affect a stock price such as global macroeconomic conditions, interest rates, etc...
