Most bitcoin have never been sold. Bitcoin is a commodity that is intended to serve as a store of value, and other commodities like gold and silver do their work as a store of value without an appreciable fraction of them ever being sold. So using the term market cap is not a misleading measure in relation to bitcoin; it is simply used by analogy to how it would be used for a company; it's not literally implying that all bitcoin is the equivalent of shareholder value.
