What Is Crypto Market Cap?
Market capitalisation is the total value of all coins currently in circulation. The formula is simple: current price multiplied by circulating supply. It is the single most useful number for comparing two cryptocurrencies, and the one beginners most often ignore.
Why price alone is meaningless
A coin priced at fractions of a cent is not cheap, and a coin priced in the tens of thousands is not expensive. What matters is the total. A token at 0.001 dollars with a supply of one trillion is worth a billion dollars. A token at 50,000 dollars with a supply of ten thousand is worth 500 million. The second is the smaller project despite the far higher price per unit.

What market cap tells you
- Relative size. A one billion dollar project doubling is plausible. A one trillion dollar project doubling requires enormous new capital.
- Risk profile. Large caps move less violently and rarely go to zero. Small caps do both far more often.
- Realistic targets. Ask what market cap a price prediction implies. Many popular targets quietly assume the coin becomes larger than the entire current crypto market.
Circulating versus fully diluted
Circulating supply counts coins available now. Fully diluted valuation, or FDV, counts every coin that will ever exist. When a project has released only ten percent of its supply, the remaining ninety percent will arrive eventually, usually to early investors and the team. A modest market cap with an enormous FDV is a warning worth taking seriously.
What it does not tell you
Market cap is not money invested and it is not liquidity. A thin market can produce a large notional valuation on very little real buying, and the same works in reverse on the way down. Always look at trading volume alongside it, which you can compare on our highest volume page.
Frequently Asked Questions
What is a good market cap for a beginner to buy?
There is no correct answer, but larger caps are generally less volatile and less likely to fail outright. Many investors keep the bulk of a portfolio in the largest few assets and treat small caps as high-risk positions.
What is fully diluted valuation?
FDV multiplies the current price by the maximum supply rather than the circulating supply. It shows what the project would be worth if every token existed today, which matters when large unlocks are still coming.
Does a higher market cap mean a better project?
No, it means a larger one. Size reflects current market opinion and liquidity, not technology or long-term prospects.
