Market cap is coin price multiplied by total supply. It matters more than price alone: a €0.01 coin with 100 billion supply is not cheap, it is a €10 billion asset. Larger market cap means more stability and harder price manipulation. For investment decisions, it signals risk level: mega-cap (BTC, ETH) is safer, small-cap is speculative. Watch the FDV too. If it is 10x the market cap, heavy dilution is coming.
