Use market capitalisation as a labelled valuation measure, not a reserve balance or an exit guarantee.
Understand the multiplication
A common market-capitalisation calculation multiplies an asset's reference price by its circulating supply. Both inputs involve definitions: the reference price may aggregate selected markets, and circulating supply depends on the provider's methodology. The resulting figure is a marked valuation. It does not record how much money has entered the asset, how much cash an issuer holds or what every holder would receive if all tried to sell.
A small trade can move a large number
Imagine one million circulating tokens and a reference price of two dollars. The marked capitalisation is two million dollars. If a thin market's reference price changes to three dollars after modest trading, the calculation becomes three million. That increase does not imply that one million fresh dollars was deposited somewhere. The example demonstrates why multiplying a marginal price across the whole supply can magnify a change in a relatively small trading venue.
Liquidity asks a different question
An executable sale depends on available bids or pool liquidity for the desired amount, along with fees and access constraints. A token can have a large marked capitalisation and little depth near its displayed price. Likewise, a large wallet's balance multiplied by the reference price is a mark, not a firm purchase offer. A useful report keeps marked value and estimated execution proceeds in separate fields with their assumptions attached.
Improve your comparison
When comparing two assets, use the same currency, observation time and supply convention. Then inspect where trading occurs, how concentrated activity is and whether the relevant venues actually support deposits and withdrawals for you. Ask how the provider handles outliers and missing supply data. A ranking can organise research, but it cannot establish quality or predict returns. Treat unexplained precision as a reason to examine inputs, not as proof that the underlying measurement is exact.
