Market capitalization (market cap) is the total value of all coins of a cryptocurrency currently in circulation, calculated by multiplying the circulating supply by the current price per coin. It’s a far more useful measure of a crypto asset’s actual size than price alone — a coin trading at $0.01 isn’t automatically ‘cheaper’ or smaller than one trading at $50,000.
Key Takeaways
- Market cap = circulating supply × current price per coin.
- A low per-coin price doesn’t mean an asset is undervalued — it could simply have a much larger circulating supply.
- Market cap is commonly used to rank and compare cryptocurrencies by relative size (large-cap, mid-cap, small-cap).
- Market cap can be manipulated or misleading for low-liquidity tokens, where a small amount of trading volume can swing the implied valuation significantly.
- ‘Fully diluted market cap’ (using total eventual supply instead of current circulating supply) is a related but different metric worth checking for tokens with a lot of supply still to be released.
Market Cap Tiers (General Convention)
| Tier | Typical Range |
|---|---|
| Large-cap | Tens of billions of dollars or more |
| Mid-cap | Roughly $1 billion – $10 billion |
| Small-cap | Under $1 billion |
Our Take
The single most common beginner mistake in crypto is comparing coins by price per unit rather than market cap — assuming a coin priced at $0.001 is ‘cheap’ and has more room to grow than one priced at $500. Price per coin is a function of supply, and supply is an arbitrary design choice each project makes; it says nothing on its own about whether an asset is over- or under-valued relative to its actual size and adoption.
Market cap itself has a real limitation worth knowing: it assumes every coin in circulation could be sold at the current price, which isn’t realistic for illiquid assets — a small-cap token’s market cap can look large on paper while its actual tradable liquidity is a tiny fraction of that number. Checking trading volume and order book depth alongside market cap gives a much more honest picture of an asset’s real size than market cap alone.
FAQs
Does a lower price per coin mean more room to grow?
Not on its own. Price per coin depends on supply, which varies enormously between projects. Market cap (price × circulating supply) is a much more meaningful measure of an asset’s actual size.
What’s the difference between market cap and fully diluted market cap?
Market cap uses the current circulating supply; fully diluted market cap uses the total supply that will eventually exist, including tokens not yet released — useful for spotting projects with a lot of future dilution ahead.
