Market cap is not money flowing into Bitcoin

One price can revalue the whole supply

Coin Metrics documents market-capitalization measures built from price and supply. The exact supply convention still needs to be checked for the selected metric. Metric definitions.

Here is a deliberately simplified example, not current BTC data. Imagine an asset with 1,000 circulating units and a reference price of $10. Its market cap is $10,000. If the reference price becomes $11 while supply stays fixed, its market cap becomes $11,000.

The $1,000 increase is the result of revaluing the supply. This calculation contains no information about how many units traded, the transaction sizes or buyers’ funding sources. It therefore cannot establish that $1,000 of new cash entered the market.

Volume answers another question

Trading volume measures activity under a provider’s conventions. The same unit can change hands repeatedly, so turnover also cannot be read directly as the amount of newly committed capital. For each number, ask whether it describes a stock, a price, a transaction total or a measured flow through a specific vehicle.

This distinction matters in a market report. “Market value increased” can be a supported statement. “Investors injected the same amount of money” requires different evidence. Precise language prevents an arithmetic observation from becoming an unsupported story about behavior.

A ratio can move without new stablecoins

Consider another hypothetical example. Stablecoins are valued at $100 and all other included crypto assets at $900. Stablecoin dominance is $100 divided by $1,000, or 10%.

Now hold stablecoins at $100 while the other assets fall to $700. Dominance becomes $100 divided by $800, or 12.5%. The ratio rose by 2.5 percentage points without any increase in the stablecoin numerator.

The observation is a change in relative market value. Calling it fresh liquidity or new “dry powder” would add a claim that this example does not support. Inspect stablecoin supply and the rest of the market separately before choosing an explanation.

A better way to write the daily note

First, name the measure and its provider. Then describe the change with the correct units: percentages and percentage points are not interchangeable. Finally, state what the measure does not reveal when that limitation is central to the interpretation.

For BTC demand through exchange-traded products, use appropriately sourced fund-flow observations rather than changes in total crypto market cap. For stablecoin liquidity, examine supply, composition and peg conditions rather than dominance alone. These are narrower observations, and that makes them more useful.
