Crypto market cap: compare supply, dilution and liquidity
A low token price does not necessarily mean a small valuation. Market capitalization connects price with circulating supply, but it cannot tell you how much you could sell or whether a project deserves its valuation.
Your task: calculate market cap and a dilution scenario, then identify the liquidity information missing from both.
Three quantities to keep separate
Price
The quoted price per unit, based on the markets and methodology used by the data provider. Thin or fragmented trading can make it misleading.
Circulating supply
The provider’s estimate of units circulating in the market. Locked holdings, vesting and available evidence can affect that estimate.
Market capitalization
Price multiplied by circulating supply. It is a valuation metric, not the amount of money deposited into a project or guaranteed cash available to sellers.
Compare two assets on the same basis
Match the timestamp and source
Record price, circulating supply and the time checked. Do not combine today’s price with an old supply figure. Investigate unavailable or disputed supply data rather than filling the gap with a guess.
Separate current supply from future supply
Fully diluted valuation (FDV) applies today’s price to a broader supply figure, commonly maximum or total supply. Check the provider’s definition. A fixed maximum may not exist, and FDV is not a forecast.
Inspect unlocks and trading depth
Check the project’s issuance and vesting schedule, then look at spread, order-book depth and trade size on the venue you would actually use. Reported daily volume is not a substitute for executable liquidity.
Worked example: cheap units, equal market caps
Asset A: $1 × 100 million circulating units = $100 million. Asset B: $0.01 × 10 billion units = $100 million too. B is not smaller just because one token costs less. If A’s circulating supply doubled to 200 million while its market cap stayed $100 million, the implied price would be $0.50. That is a constant-market-cap scenario, not a price prediction.
Three mistakes to avoid
Reading market cap as an exit budget
A $100 million market cap does not mean buyers are waiting to pay $100 million. Your sale can consume available bids and move the execution price.
Ignoring the order book
Illustrative asks: one unit at $100, one at $101 and one at $103. Buying all three costs $304, averaging about $101.33 before fees—about 1.33% above the first quote.
Using one number as a quality score
Market cap and FDV say little about token-holder rights, concentration, security or actual demand. Compare those separately; a large number is not evidence of a safe investment.
Try it: calculate, then ask what is missing
A token costs $0.04, has 250 million circulating units and a maximum supply of 1 billion. Calculate circulating market cap and maximum-supply FDV. Can either tell you the cost of buying $5,000 worth?
Show the reasoning
Market cap is $10 million; FDV is $40 million. Neither supplies an executable quote. You still need the venue’s order book or swap quote, spread, price impact and fees for that trade size.
