Market cap, or market capitalization, is the total value of all the coins that have been mined in a cryptocurrency. It's calculated by multiplying the number of coins in circulation by the current market price of a single coin. This metric helps investors understand a cryptocurrency's size, stability, and growth potential.
Think of market cap like a snapshot of a crypto's overall value. Large-cap cryptos like Bitcoin and Ethereum are generally considered more stable, while small-cap cryptos are riskier but might offer higher returns ¹ ² ³.
