Market Cap (Market Capitalization)

The total value of a cryptocurrency, calculated by multiplying the price per token by the circulating supply.

For stablecoins pegged to $1, market cap and circulating supply are essentially the same number. If there are 75 billion USDC in circulation at $1 each, the market cap is $75 billion.

Market cap is useful for comparing stablecoins. USDT (Tether) has the largest stablecoin market cap, followed by USDC. A higher market cap generally means more liquidity and wider adoption.

For non-stablecoin crypto assets, market cap fluctuates with price. Bitcoin's market cap changes every second as its price moves. For stablecoins, market cap mainly changes through minting and redemption.
