Market cap
The total value of a crypto asset, found by multiplying its price by the number of coins in circulation.
Market cap is the total value of a crypto asset. You work it out with one sum: price multiplied by circulating supply. If a coin trades at $2 and 50 million of them are in circulation, its market cap is $100 million. The figure tells you how big the asset is, not how much a single coin costs.
That distinction trips up newcomers. A coin priced at $0.50 can be worth far more in total than one priced at $40,000, because supply differs by orders of magnitude. Bitcoin trades in the tens of thousands per coin, yet there will only ever be 21 million of them. A meme coin might trade at a fraction of a cent while trillions exist. Price alone tells you nothing.
Why does it matter? Market cap is the quickest way to rank and compare assets. Traders sort coins into rough tiers: large-cap names in the tens of billions, mid-caps in the low billions, and small-caps below that. Larger caps tend to show lower volatility and deeper markets, while small-caps can swing hard on modest buying.
Watch the gap between circulating supply and total supply. Some projects keep most of their coins locked or unissued, so the headline cap looks small. Then those tokens release into the market. People also quote fully diluted valuation, which prices every coin that will ever exist as if it traded today. That can be many times the live cap. It has misled plenty of buyers.
Treat market cap as a sizing tool, not a verdict on quality. A high cap does not make an asset sound. A low one does not make it a bargain. It measures what the market currently pays in aggregate, nothing more. Pair it with trading volume, the supply schedule and what the project actually does before you read anything into the number.
