Market Cap
Quick definition
Total value of a coin: price multiplied by circulating supply.
Market capitalization = current price × coins in circulation. It's the standard way to compare crypto sizes — a $1 coin with 10 billion supply is 'bigger' than a $100 coin with 1 million supply.
Beginners often misread cheap unit prices as upside ('it only needs to reach $1!'). Market cap exposes the math: what matters is total valuation, not price per coin.
