Crypto market cap,
read like a stock investor.
You already know share price alone tells you nothing; market cap and earnings do. Crypto works the same way, with a few new terms: circulating supply, FDV and unlocks. Here is how they map to stocks.
How is crypto market cap calculated?
Same formula: market cap = price × quantity. For coins, the quantity usually means circulating supply, the coins already trading in the market.
| In stocks | In crypto | Meaning |
|---|---|---|
| Share price | Coin price | Price of one unit, usually in USDT or USD |
| Float | Circulating supply | Units already trading |
| Shares outstanding | Total / max supply | All units that exist or ever will |
| Market cap | Market cap | Price × circulating supply |
| Fully diluted cap | FDV | Price × max supply |
| Lock-up expiry | Token unlock | Team and investor coins becoming sellable |
Bitcoin has a hard cap of 21 million coins, about 19.9 million of which have been mined. At roughly $83,000 in late September 2026, that's a market cap of about $1.65 trillion, the largest in crypto.
Circulating vs total supply, and what FDV means
FDV (fully diluted valuation) is price × maximum supply: what the project would be worth if every coin were already out. The gap between market cap and FDV is supply still to come.
| Coin A | Coin B | |
|---|---|---|
| Market cap | $1B | $1B |
| Share circulating | 90% | 15% |
| FDV | about $1.1B | about $6.7B |
| Future selling pressure | Low | High: 85% of supply still to unlock |
Stock investors know prices often sag around lock-up expiries. Token unlocks work the same way, and new coins often launch with only 10%–20% circulating.
Is a cheap coin undervalued?
No. A $0.01 coin with 100 billion units has a $1 billion market cap. Reaching $1 would take a $100 billion valuation. Meanwhile, bitcoin's high unit price doesn't stop you buying 0.00001 BTC.
A $3 stock isn't necessarily cheaper than a $300 one. The same logic applies to coins: judge by market cap, usage and trading volume, not unit price.
Do cryptocurrencies have P/E ratios or pay dividends?
| Source | Stocks | Most crypto |
|---|---|---|
| Dividends from profits | Yes | No |
| Audited financial reports | Required for listed companies | No standard; voluntary at best |
| P/E valuation | Yes | Rarely possible |
| Staking or earn yield | No | Some coins; not a dividend, carries lock-up and price risk |
| Buybacks | Share buybacks | Some projects buy back and burn tokens |
Coin prices depend mostly on supply, demand, usage and sentiment, which is one reason they swing so much more than stocks.
How can a stock investor size up a coin?
- Market-cap rank: start with the top 20; they're liquid and harder to manipulate.
- Circulating share and unlock schedule: a low float means supply is coming.
- 24-hour volume: thin volume means you may not be able to sell.
- Where it's listed: coins only on obscure venues carry more risk.
- Real usage or revenue: on-chain activity beats slogans.

Crypto valuation:
FAQ.
01Where can I see crypto market cap rankings?
CoinGecko and CoinMarketCap rank coins by market cap, and the OKX markets page can sort by market cap too.
02Which crypto has the largest market cap?
Bitcoin, followed by ether and stablecoins such as USDT. Stablecoins are large but pegged to $1, so they aren't growth assets.
03Is a low FDV always better?
Not on its own. A small gap between market cap and FDV means less unlock pressure, but demand and usage matter just as much.
04Does circulating supply change?
Yes. New bitcoin is mined daily, many projects unlock tokens on a schedule, and some burn tokens to reduce supply.
05Why do sites show different market caps?
They count circulating supply differently, for example excluding locked or lost coins.
06Are small-cap coins good for beginners?
They rise fast and fall fast, and are easier to manipulate. Start with large caps.
