How to compare cryptocurrencies
Market cap, not price. A coin priced at $0.10 isn't “cheaper” than one at $100 — price alone ignores how many coins exist. Market cap (price × circulating supply) is what actually ranks two coins against each other, and it's the first number to compare.
Supply matters. Compare circulating supply against max supply. A coin with most of its supply already circulating faces less future sell pressure from unlocks and emissions than one with a large share still to be released.
Volume shows real activity. 24-hour trading volume relative to market cap indicates how actively a coin trades and how easily you can buy or sell it. Consistently thin volume means bigger spreads and more volatile moves in both directions.
