A cryptocurrency costs $0.10 and another costs $1,000. Which one is cheaper? The correct answer is: we cannot know by looking at the price. And in some cases, even market cap is not enough to understand how the market is actually valuing a project.
This is where crypto FDV, or Fully Diluted Valuation, comes into play. It is one of the most important metrics in a cryptocurrency's tokenomics and, at the same time, one of the most misunderstood. Understanding the difference between market cap and FDV reveals something that price alone does not show: how much supply exists today, how much could enter the market in the future, and how the project's theoretical valuation changes when those tokens are taken into account as well.
What is the market cap of a cryptocurrency?
Market capitalization, or market cap, measures the theoretical value of the tokens currently considered to be in circulation.
The formula is simple:
Market Cap = Token Price × Circulating Supply
If a token is worth $2 and there are 100 million tokens in circulation, its market cap is $200 million.
This makes it possible to compare cryptocurrencies with completely different unit prices. A token priced at $0.01 can have a much larger market cap than a coin worth $500 simply because many more units of the first asset exist.
There is, however, a very common mistake: a $1 billion market cap does not necessarily mean that investors have put $1 billion into the project.
Market capitalization is derived by applying the latest market price to the entire circulating supply. In an illiquid market, even a relatively modest amount of capital can move the price and, as a result, significantly change the market cap.
To explore this further, our DYOR guide to evaluating a cryptocurrency also looks at liquidity, tokenomics, token utility and other fundamental metrics.
What is FDV in crypto?
FDV stands for Fully Diluted Valuation.
Its purpose is to answer a different question from market cap:
what would the project theoretically be worth at the current price if we also considered the supply that is not circulating today?
An important clarification is needed here. Major data platforms do not necessarily use the same supply figure in their calculations. CoinMarketCap uses maximum supply in its methodology, while CoinGecko generally uses total supply. As a result, the same asset may show slightly different values depending on the source.
The principle, however, remains the same:
FDV = Current Price × Supply Used for the Fully Diluted Valuation
Looking only at market cap, the project appears to be worth $100 million. Looking at FDV, however, shows that at the current price the theoretical valuation of the entire supply would be $1 billion.
The difference is tenfold.
This does not mean the token must necessarily lose 90% of its value. It means that 90% of the supply considered in the example is not yet represented in the circulating supply, and it is necessary to understand when, how and to whom it will be distributed.
Why can an FDV much higher than market cap matter?
The issue is not a high FDV by itself. The issue is what may sit behind it.
Some tokens may be locked for early investors, the team, the foundation, treasury, ecosystem incentives, airdrops or staking programs.
These tokens can gradually enter circulation through vesting and token unlocks.
When circulating supply increases, there are more tokens that can potentially be traded. If demand grows at the same pace or faster, the market can absorb the new supply. If supply grows much faster than demand, price pressure can emerge.
The key word is therefore potentially.
An unlock does not automatically mean a sale. An investor, the team or a foundation can receive unlocked tokens and continue to hold them. However, after the unlock those tokens have a greater chance of entering the market than when they were restricted.
Low float, high FDV: when a few tokens create a huge valuation
In crypto, there is a structure known as low float, high FDV.
“Low float” means that only a small percentage of the supply is actually in circulation. If initial demand meets a limited number of available tokens, the price can rise quickly.
Applying that price to the entire future supply can then produce an enormous FDV.
A project can therefore appear relatively small in market-cap rankings while already being valued, on a fully diluted basis, like much more mature protocols.
We have already seen this dynamic when analyzing Hyperliquid's launch and tokenomics, where the relationship between circulating supply and fully diluted valuation was one of the key elements to watch.
Extreme cases such as the RaveDAO rally also show why a valuation derived from price should always be read together with liquidity, supply and market structure.
Does a high FDV mean a crypto is overvalued?
No.
It is one of the most common mistakes when interpreting the metric.
An FDV of $10 billion does not, by itself, mean a project is worth too much. Likewise, a low FDV does not automatically mean the token is cheap.
The question is what justifies that valuation.
A protocol with high revenue, growing usage, controlled supply and structural demand can support a very different valuation from a token with no product, users or liquidity.
FDV also implicitly assumes that today's price can be applied to a much larger quantity of tokens. That is a theoretical assumption: if millions of new tokens actually entered circulation, the price could change.
For this reason, FDV is useful as a signal to investigate, not as a verdict.
The FDV/Market Cap ratio
A quick way to identify potential differences between current and future supply is to compare FDV and market cap.
In the previous example:
FDV / Market Cap = 10
The closer the ratio is to 1, the more the supply considered in the diluted valuation is already represented in the circulating supply. The higher the ratio becomes, the greater the difference between what circulates today and what could be considered in the future.
But here too, there is no universally “good” or “bad” number.
A high ratio with unlocks spread over ten years is very different from the same ratio when large amounts of tokens are due to be unlocked over the next six months.
The 6 things to check beyond FDV
Before interpreting a fully diluted valuation, it is useful to verify at least six elements.
1. Circulating supply. How many tokens are actually considered to be in circulation today?
2. Total and maximum supply. How many tokens already exist, and how many can exist in total?
3. Unlock schedule. When will new supply enter circulation?
4. Recipients. Are the tokens allocated to the community, team, investors, treasury or foundation?
5. Emissions and burns. Does the protocol continuously create new tokens? Are there mechanisms that destroy some of them?
6. Liquidity. How deep is the market where the token is actually traded?
The last point is particularly important. An asset can show an FDV of billions of dollars while having very limited liquidity. In that case, the theoretical valuation is derived from a price that could change rapidly even with relatively small orders. In our CEX vs DEX guide, we explain how liquidity depth and slippage directly affect trade execution.
Why CoinGecko and CoinMarketCap can show different data
There is one final detail that is often ignored even by experienced users: data platforms can use different methodologies.
CoinMarketCap currently defines Fully Diluted Valuation using maximum supply multiplied by price. CoinGecko generally uses total supply and specifies that FDV represents a theoretical valuation.
In 2026, CoinGecko also introduced Outstanding Token Value, a metric designed to represent the valuation of supply already available using more granular criteria than the simple distinction between circulating supply and total supply.
This means that comparing Token A's FDV from one platform with Token B's FDV from another can lead to inaccurate conclusions.
When comparing different assets, it is preferable to use the same source and the same methodology.
The bigger picture
FDV is not designed to predict which cryptocurrency will rise or fall.
It is designed to help us ask a better question.
When we see a token with a relatively small market cap, we should ask: how much of the project am I actually seeing in today's supply?
If only a small share of the tokens is in circulation, the current price is valuing a market with a very different supply profile from the one that may exist in the years ahead.
That does not automatically make the project negative. But it completely changes how it should be analyzed.
Price, market cap, FDV, unlocks, distribution, liquidity and protocol usage are pieces of the same puzzle. Taken individually, they can tell a misleading story. Read together, they provide a much clearer understanding of a cryptocurrency's economic structure.
And that is exactly the most useful role of FDV: not to tell us what a token is “really” worth, but to show us which part of its future valuation today's market cap may not be telling us.
