A token can look cheap by market cap and be catastrophically expensive by fully diluted valuation, and the gap between the two numbers is where most crypto losses quietly begin. This guide explains market cap and FDV, why the difference matters more than either number alone, how token unlocks turn FDV into future selling pressure, the low-float high-FDV trap that defined a market cycle, and how to read both numbers before you buy.

Two traders look at the same token. The first checks its market capitalization, sees a modest number, and concludes the token is cheap with room to grow. The second checks its fully diluted valuation, sees a figure ten times larger, and concludes the token is a time bomb of future selling. They are looking at the same asset, and they are both reading real numbers. The gap between what they see is one of the most important and least understood concepts in crypto valuation, and misreading it has cost more retail money than almost any other single mistake.

Market capitalization and fully diluted valuation, FDV, are the two headline ways to size a token, and each answers a different question. Market cap asks what the tokens in circulation right now are worth. FDV asks what all the tokens that will ever exist would be worth at today’s price. When most of a token’s supply is already circulating, the two numbers are close and the distinction barely matters. When most of the supply is still locked, waiting to be released over years, the two numbers diverge enormously, and the space between them is a map of future selling pressure that the market cap alone completely hides.

This guide explains both numbers and the relationship that matters more than either. It covers what market cap and FDV actually measure, why circulating supply is trickier than it sounds, how the unlock schedule turns FDV into a calendar of future dilution, the low-float high-FDV trap that defined the 2024 token cycle and its aftermath, the specific ways these numbers mislead, and the practical checklist for reading a token’s valuation before the locked supply reads it to you.

The two numbers, precisely

Market capitalization is the simplest valuation in crypto: circulating supply multiplied by current price. A token trading at $2 with 100 million coins in circulation has a $200 million market cap. It answers the question, what is the market currently valuing this token at, based on the coins actually available, and it is the number that appears first on every tracker and the one most people mean when they call a token large or small.

Fully diluted valuation multiplies the same price by the total supply that will ever exist, not just what circulates today. If that same $2 token has a maximum supply of one billion coins, of which only 100 million circulate, its FDV is $2 billion, ten times its market cap. FDV answers a different question, what would this token be worth if every coin that will ever exist traded at today’s price, and it is, in effect, the valuation the market is implicitly assigning to the entire project if you assume the price holds as the rest of the supply arrives.

The relationship between the two is the whole game, and it is captured by one ratio: circulating supply divided by total supply, the float. A token with 90% of its supply circulating has a market cap close to its FDV, the two numbers nearly agree, and there is little hidden supply to worry about. A token with 10% of its supply circulating has an FDV ten times its market cap, and 90% of its eventual supply is sitting locked somewhere, scheduled to enter the market over time. The lower the float, the wider the gap, and the wider the gap, the more the market cap flatters the token by hiding what is coming.

Circulating supply is trickier than it looks

Before trusting either number, it is worth knowing that circulating supply, the input to market cap, is itself a slippery figure. It is meant to count the coins genuinely available to trade, excluding locked, reserved, and unreleased tokens, but the accounting varies by source and can be gamed. Projects sometimes report circulating supply generously, counting tokens that are technically unlocked but held in foundation or team wallets that will not actually sell, or excluding tokens in ways that flatter the market cap. Different data providers apply different methodologies, which is why the same token can show slightly different market caps on different trackers.

This matters because market cap inherits every ambiguity in circulating supply. A token whose reported circulating supply is artificially low will show an artificially low market cap, making it look cheaper than it is, while its FDV, based on the harder-to-fudge total supply, tells the less flattering truth. The discipline is to treat circulating supply as a claim to be checked rather than a fact, and to always read it alongside total supply and the unlock schedule, because the gap between circulating and total is not empty space, it is a queue.

The unlock schedule: FDV as a calendar

Here is the insight that turns FDV from an abstract number into a practical warning: the difference between circulating supply and total supply does not stay locked forever. It is released on a schedule, the vesting or unlock schedule, and that schedule is a calendar of future selling pressure written years in advance.

When a project launches, it typically sells or allocates only a fraction of its tokens, keeping the rest locked for the team, investors, treasury, and ecosystem, released gradually over months or years. Each release, an unlock, converts locked tokens into circulating ones, expanding the supply that can be sold. The tokens existed all along, they were always counted in FDV, but they become sellable only when they unlock, the anticipatory dynamic that governs every large scheduled release. This is why FDV matters: it is not a hypothetical, it is a preview of the supply that is contractually scheduled to arrive, and the unlock calendar tells you exactly when.

The mechanical consequence is relentless. A low-float token with a high FDV faces a headwind that a high-float token does not: a steady stream of newly unlocked tokens, often released to insiders sitting on large gains, entering a market that must absorb them just to keep the price flat. If demand does not grow at least as fast as supply unlocks, the price falls, not because anything went wrong with the project, but because the supply side of the equation was scheduled to overwhelm the demand side from the start. Reading a token’s unlock schedule is reading its future selling pressure, and a token whose FDV dwarfs its market cap is a token whose price chart is fighting its own supply calendar for years, the same supply-versus-demand scissors that shapes entire market cycles.

The low-float, high-FDV trap

The gap between the two numbers is not just a technical curiosity; it defined an entire market cycle and taught a brutal lesson. In the 2024 token era, a wave of projects launched with very low floats and very high FDVs: a small fraction of supply circulating, valuations that looked reasonable by market cap, the fair-launch platforms industrializing exactly this structure at scale, as their own house token’s supply cliff showed but enormous by FDV, and long vesting schedules loading the future with unlocks.

The pattern worked, briefly, because low float is a price accelerant in both directions. With few tokens available to trade, modest demand produces dramatic price gains, thin supply amplifies buying the way it amplifies everything, the same launch-curve dynamic that prices earliness into every memecoin, and the early charts looked spectacular, drawing in buyers who checked the market cap, saw room to grow toward the FDV, and bought. Then the unlocks began. Wave after wave of locked supply, much of it held by insiders who had bought far lower, entered the market, and the same thin float that amplified the rise now had to absorb a rising tide of new supply against fading demand. The result was a cohort of tokens that spent the following period grinding relentlessly lower, not from any failure of their projects but from the arithmetic they launched with: valuations set at the top, supply scheduled to arrive into weakness, and a float too thin to defend the price on the way down. The lesson the cycle burned into the market was that a low market cap next to a high FDV is not a bargain waiting to grow, it is frequently a warning that the price you see was manufactured by scarcity that is scheduled to end.

A worked comparison: two tokens, same market cap

Set two tokens side by side to see the gap do its work. Token A trades at $1 with 800 million of its 1 billion total supply circulating: an 80% float, a market cap of $800 million, and an FDV of $1 billion. The two numbers nearly agree, only 200 million tokens remain to unlock, and whatever selling pressure they represent is modest against the supply already trading. Token B also has an $800 million market cap, at $4 with 200 million of a 1 billion total supply circulating: a 20% float and an FDV of $4 billion. Same market cap, radically different situations. Token B has four times the eventual supply still locked, 800 million tokens queued to arrive, and its price must climb a supply escalator running the other way for as long as those unlocks continue.

A buyer comparing the two by market cap alone sees a tie and might pick Token B for its higher price and apparent momentum. A buyer reading float and FDV sees that Token A is most of the way through its dilution while Token B has barely begun, and that Token B’s $4 price is being held up by a float one-quarter the size, exactly the scarcity that will reverse as supply unlocks. Neither token is automatically good or bad, but they are not remotely the same investment, and only the second reading reveals it. The market cap said they were equal; the FDV and the float said one had a tailwind and the other a four-year headwind.

What responsible vesting looks like

Because the guide has dwelt on the trap, fairness requires describing the healthy version, since a high FDV is not inherently a red flag. Responsible token design vests supply in ways that align insiders with long-term holders rather than setting them up to dump: meaningful cliffs before any team or investor tokens unlock at all, long linear release schedules that spread supply over years instead of dropping it in cliffs, allocations weighted toward ecosystem and community rather than concentrated in early investors, and transparent, published schedules that let the market price the dilution in advance instead of being surprised by it. A project with a high FDV but a slow, transparent, community-weighted unlock schedule and genuine demand growth can absorb its supply gracefully, and many legitimate networks have.

The distinction that matters is therefore not high FDV versus low FDV but scheduled dilution versus demonstrable demand. A token whose users, revenue, or adoption are growing fast enough to soak up its unlocks can carry a high FDV comfortably; a token whose only source of price support was a thin float, facing large near-term unlocks to insiders already in profit, cannot. Reading valuation well means holding the FDV and the unlock schedule in one hand and the demand trajectory in the other, and asking the only question that ultimately sets the price: is real demand growing at least as fast as scheduled supply. When the answer is yes, a high FDV is a sign of ambition; when it is no, the same number is a countdown.

How the numbers mislead, in both directions

Each number lies in its own way, and knowing how is the point of reading them together. Market cap misleads by hiding the future: it makes low-float tokens look cheap and small, showing only the tokens that circulate today and silently omitting the locked supply queued to dilute them, which is exactly why the low-float trap works, buyers who anchor on market cap are reading a number designed, whether intentionally or not, to look better than the token’s real valuation. FDV misleads by ignoring time and probability: it values every future token at today’s price as if all supply existed now, which overstates the case for tokens whose locked supply may be burned, may never fully release, or may be years away, and it treats distant, uncertain dilution as if it were present, which can make a healthy long-vesting project look scarier than it is.

The truth lives in reading both against the unlock schedule. A high FDV is not automatically damning, plenty of legitimate projects launch with most supply locked and vest it responsibly, but a high FDV with imminent, large unlocks to insiders sitting on gains is a specific and readable danger. A low market cap is not automatically a bargain, it may simply be the visible tip of a much larger diluted valuation. The numbers are inputs to a judgment, not verdicts on their own, and the judgment requires the third document neither number contains: the vesting schedule that says how much supply arrives, when, and to whom.

The practical checklist

Reading a token’s valuation honestly comes down to a short sequence. First, check the float: circulating supply divided by total supply, because it tells you at a glance how much of the story the market cap is hiding, a float near 100% means the two numbers agree, a float near 10% means the market cap is showing you a tenth of the eventual supply. Second, read the gap: compare market cap to FDV, and treat a large gap as a flag to investigate, not a verdict, but never a number to ignore. Third, pull the unlock schedule: find out how much locked supply exists, when it releases, and to whom, because that calendar is the future selling pressure the FDV only summarizes, and imminent large unlocks to early investors are the specific danger the low-float trap is built on. Fourth, weigh demand against supply: ask whether the project’s growth in users, revenue, or adoption is plausibly fast enough to absorb the scheduled unlocks, because that race, demand growth against supply release, is what actually sets the price over time.

The deeper habit, beneath the checklist, is refusing to let a single number make the decision. Crypto’s most expensive lesson is that a token can be simultaneously cheap by one honest measure and dangerously expensive by another, and that the two measures diverge precisely in the tokens most aggressively marketed as opportunities. Market cap tells you what the market pays for what exists. FDV tells you what it is implicitly paying for what is coming. Neither is the truth alone; the truth is in the space between them, on the unlock calendar, and the traders who read that space before they buy are reading the one part of a token’s valuation that the price chart, the marketing, and the market cap are all designed to keep them from seeing until it is too late.

A closing note on where these numbers come from, because trusting a tracker blindly reintroduces the very ambiguity the guide warns against. Market cap and FDV are computed from supply figures that projects self-report and aggregators standardize imperfectly, total supply can change if a project mints or burns tokens, maximum supply is sometimes uncapped entirely, which makes FDV undefined or meaningless, and circulating supply, as covered above, is the softest input of all. The disciplined reader treats the headline numbers as starting points and verifies the underlying supply mechanics: is there a hard cap, is supply inflationary, are tokens being burned, and does the unlock schedule match what the tracker implies. These checks take minutes and routinely overturn the first impression, a token with an uncapped supply has no true FDV, a token with aggressive burns may see supply shrink instead of grow, and a token whose emissions never end is diluting holders forever regardless of any headline ratio. The two numbers are tools for asking better questions, not answers to be trusted on sight, and the space between them, mapped against the real supply schedule, is where a token’s honest valuation actually lives.
