Why Market Cap Is a Poor Comparison Tool

Market capitalisation is the default comparison metric in this sector. It is the product of two numbers, one of which is unreliable and the other of which is set by the marginal trade.

Problem one: the supply figure is not standard

Circulating supply excludes locked, vested and reserved tokens. How each provider treats those differs.

A token where a small fraction of the total supply circulates can show a modest market capitalisation while a far larger amount is scheduled to enter circulation on a published timetable. Fully diluted valuation attempts to address this and produces its own distortion, since it values tokens that may never be issued.

Neither figure is wrong. They measure different things, and they are frequently compared to each other.

Problem two: the price is set by the marginal trade

Market capitalisation multiplies the entire supply by the price of the last small trade.

For an asset with deep liquidity, that is a reasonable approximation of what the whole could be worth. For an asset with a few hundred thousand dollars of depth, it is arithmetic without meaning, because attempting to sell any substantial portion at that price is impossible.

The figure implies that the market could absorb the whole supply at the current price. For most assets it demonstrably could not.

Problem three: it invites comparisons between unlike things

A settlement network, a smart contract platform, a stablecoin and a governance token are compared in a single ranked list, as though the number described the same property in each case.

For a stablecoin, market capitalisation is a measure of how much has been issued, which is genuinely informative. For a governance token with no cash flows, it is a measure of what people have paid, which is informative about sentiment and about nothing else.

What to use instead

Depth within one percent of mid. Directly observable, expensive to fake, and it tells you what could actually be traded.

Volume from venues with verified reporting. Venue-level figures from regulated platforms, such as a crypto acquiring provider, rather than aggregated totals that have historically included fabricated activity.

Fees paid by users. For networks, revenue from actual usage is the closest thing to a fundamental.

Supply schedule. Tokens entering circulation over the next twelve months, as a share of current circulating supply. This is frequently the most price-relevant fact about a token and it almost never appears in a comparison table.

Where market cap is fine

Ranking the largest assets, where liquidity is deep and the supply figure is settled. At the top of the list it is a reasonable shorthand.

The further down the list it is applied, the less it means, and it is applied all the way down.
