What is market cap in crypto?

Market cap (market capitalization) is the total value of all the coins in circulation. The formula is simple: price × circulating supply.

Why price alone is misleading

A coin priced at $0.001 isn't "cheaper" than one at $50,000 in any meaningful sense. If the $0.001 coin has trillions of coins in circulation, its market cap could be enormous. Market cap tells you how big a project is; price alone doesn't.

Large-cap vs small-cap

Bitcoin and Ethereum are the largest by market cap and are generally less volatile than tiny coins. Small-cap coins can move much more dramatically — both up and down — because it takes far less money to swing their price. Bigger price swings mean bigger risk.

A caution

Market cap can be misleading if most coins are held by a few wallets, or if trading volume is thin. Always look at market cap and real trading volume together — see both live on any coin page.

Frequently asked

What is market cap in crypto?

Market cap is a coin's current price multiplied by its circulating supply, giving a rough measure of its total size. It helps you compare coins more fairly than price alone.

Does a low coin price mean it is cheap?

Not necessarily. A coin with a low price but a huge supply can have a very large market cap, so judging 'cheap' by price alone is misleading.

What is fully diluted valuation?

It is the market cap calculated as if every coin that will ever exist were already in circulation. It can be far higher than the current market cap if many coins are still unreleased.
