Crypto market cap explained: Bitcoin vs gold and Apple

The market capitalization of a cryptocurrency is its price multiplied by the number of coins currently in circulation. The figure tells you how much the market would pay for all circulating units of a coin combined if each were valued at the current price. On Friday morning, November 6, the entire crypto market came to around $2.58 trillion according to data from CoinGecko, the equivalent of about 2.30 trillion euros. Bitcoin alone accounted for a good $1.53 trillion of that.

The figure is the main sorting key of every crypto list, from the ranking on CoinMarketCap to our overview of the largest coins. But the metric has limits that many investors only notice when a token is barely tradable despite a high rank. This guide explains how the figure is calculated, what it reveals about a coin and where it can lead you astray.

What is market cap in crypto?

Market capitalization, market cap for short, is the notional total value of all circulating units of an asset. The term comes from the stock market, where the share price is multiplied by the number of shares issued to give a company's market value. With cryptocurrencies, the circulating supply takes the place of the share count.

The circulating supply is the number of coins or tokens that can be freely traded. Locked tokens held by founding teams, a foundation's reserves or coins not yet mined are not included. This is exactly where the room for interpretation begins, because the data providers decide for themselves which holdings count as freely tradable.

The difference from the price matters. The price tells you what a single unit costs. Market cap tells you how large the whole project is valued in the market. Two coins with the same price can differ in size by a factor of a thousand if one has a thousand times more units in circulation.

Market cap formula: price times circulating supply, using Bitcoin as an example

The calculation is simple and can be checked with any calculator:

Market cap = current price × circulating supply

Take Bitcoin as of November 6: around 20.11 million BTC were in circulation, and the price stood at about $76,140. That gives a market capitalization of a good $1.53 trillion. In euros, at a price of about 68,170 euros per BTC, it comes to around 1.37 trillion euros.

Because the price changes around the clock, market cap also changes every minute. The circulating supply of Bitcoin, by contrast, moves only slowly: new coins are created exclusively through mining, and the maximum supply is fixed at 21 million BTC. With other tokens the circulating supply can jump, for example when locked holdings are released. Market cap then rises even though the price stays the same or even falls.

What the calculation leaves out

Market capitalization is not money sitting somewhere. No account holds $1.53 trillion ready for Bitcoin. The figure values every coin at the price of the last trade, even if only a small fraction of them actually changed hands. If all holders wanted to sell at the same time, the achievable price would be far below the last quoted price.

Total crypto market cap: $2.58 trillion after a 6.5 percent daily drop

Total crypto market capitalization is the sum of the individual values of all tracked coins and tokens. On November 6, CoinGecko listed almost 22,840 active cryptocurrencies and arrived at around $2.58 trillion. Within 24 hours the total value had fallen by about 6.5 percent, part of the sell-off that has gripped the market since the middle of the week.

The total is a useful thermometer for market sentiment. If it rises over weeks, capital is flowing into the sector; if it falls, investors are pulling money out or prices are slipping across the board. The percentage change is more telling than the absolute value, because it makes days and years comparable.

If you want to follow the trend regularly, you will find the totals, the dominance of individual coins and 24-hour volume on data sites and in portfolio apps. Which crypto analytics platforms provide which metrics, and what they cost, is covered in a separate comparison.

Bitcoin dominance at 59 percent: the market share of the largest coin

Bitcoin dominance is Bitcoin's share of total crypto market capitalization. On November 6 it stood at around 59.2 percent according to CoinGecko. More than half the value of all cryptocurrencies is therefore concentrated in a single coin.

Behind it came Ethereum with about 10.6 percent and the stablecoin Tether (USDT) with just under 6.9 percent. BNB accounted for around 3.5 percent and XRP for just under 3.0 percent. The five largest assets thus held over 83 percent of the market between them, while the remaining 22,000-plus coins share the rest.

Dominance is seen as a gauge of whether investors are putting money into Bitcoin or into altcoins. When it rises, investors often rotate into the market leader they regard as safer, typically during weak phases. When it falls significantly over a longer period, traders speak of an altcoin season. As a signal, though, the metric is blurry, because growing stablecoin holdings push dominance down mathematically without a single altcoin having risen.

Price per coin is misleading: Zcash costs over a thousand times more than XRP and is worth less

The most common mistake in the crypto market is focusing on the unit price. A coin costing a few cents looks cheap and seems to have plenty of room to rise, while a coin costing several thousand dollars looks expensive. Market capitalization shows why that impression is deceptive.

A comparison from November 6: Zcash cost around $1,292 per coin, XRP around $1.20. One Zcash was thus more than a thousand times as expensive as one XRP. By market capitalization the ratio was reversed: XRP came to about $76 billion, Zcash to around $22 billion. The reason is the circulating supply. A little over 17 million Zcash coins are in circulation, compared with more than 63 billion XRP.

When asking whether a coin can still rise, market capitalization is therefore the right measure. A token priced at $0.0001 that is supposed to rise tenfold would have to increase its total value tenfold. If it has a quadrillion units in circulation, it would need a valuation higher than Bitcoin's to do so. The calculation takes seconds and protects you from promises that already fail on the arithmetic.

Rank 12 among all assets: Bitcoin between Meta and Broadcom

Market capitalization makes crypto comparable with other asset classes. The website CompaniesMarketCap lists companies, precious metals and cryptocurrencies in a single ranking. On November 6, gold sat at the top with around $28.4 trillion, followed by Apple with about $5.0 trillion and Nvidia with around $4.4 trillion.

Bitcoin ranked 12th with about $1.53 trillion, just behind Meta Platforms and ahead of Broadcom and Tesla. Gold was thus valued at a good 18 times the size of Bitcoin, Apple at a good three times.

Such comparisons have a catch you should be aware of. For gold, data providers estimate the total amount ever mined, so the circulating supply is an assumption. Behind a company's market value lies a business with revenue and profit; behind Bitcoin there is none. The numbers show the order of magnitude, but they say nothing about which value is appropriate.

A reference figure, not a price target

How far Bitcoin is from gold is easy to calculate: with around 20.11 million coins in circulation, a market cap of $28.4 trillion would correspond to a price of about $1.41 million per BTC. That is pure arithmetic as of November 6 and not a forecast. The value of gold changes too, and no one can say whether Bitcoin will ever reach that size.

Large cap, mid cap, small cap: size categories in the crypto market

In the crypto market, coins are commonly sorted into categories by market capitalization. A widely used rule of thumb, though not a binding standard, distinguishes three groups:

• Large caps with a market capitalization above $10 billion. On November 6 these included a good dozen assets, among them Bitcoin, Ethereum, XRP, Solana and several stablecoins.
• Mid caps between roughly $1 billion and $10 billion, often established layer-1 blockchains, DeFi protocols or utility tokens with their own use case.
• Small caps below $1 billion. This is where the vast majority of the more than 22,000 tracked coins sit, including many young projects and meme tokens.

The smaller the market cap, the more the price usually swings. A buy order of just a few hundred thousand dollars can move a small cap by double-digit percentages, while the same sum goes unnoticed in Bitcoin. This works in both directions: the chance of large gains comes with high risk, up to and including a total loss.

Market cap vs FDV: 36 billion XRP sit outside circulation

Alongside market capitalization, most data sites show a second metric, the fully diluted valuation, or FDV. FDV applies the current price to a coin's maximum supply, meaning every unit that can ever exist. It shows how large a project would be valued if all tokens were already in circulation.

With XRP the gap is marked. Of a maximum of 100 billion XRP, around 63.5 billion were in circulation on November 6, so a good 36 billion were not. Market cap stood at about $76 billion, FDV at around $120 billion. With Bitcoin, by contrast, over 95 percent of the maximum supply has already been mined, and market cap and FDV are close together.

The larger the gap, the more supply can come onto the market in future. Whether that weighs on the price depends on the schedule and on demand. How to look up circulating supply, total supply and FDV yourself before buying a newly listed token is shown in our August guide on FDV and circulating supply.

Stablecoins in the ranking: USDT and USDC grow with issuance, not with price

Stablecoins regularly feature among the ten largest cryptocurrencies. On November 6, Tether (USDT) had a market capitalization of around $178 billion, USD Coin (USDC) about $70 billion. For them, the metric works differently than for ordinary coins.

A stablecoin is a token whose price is pegged to a currency such as the US dollar. Because the price almost always sits at one dollar, market cap essentially equals the number of tokens issued. The value grows when the issuer creates new units against deposits and shrinks when tokens are redeemed. A rising stablecoin market cap is therefore not a price gain but a sign of fresh capital standing ready in the crypto market.

Limits of the metric: trading volume and a thin free float

A high market capitalization does not mean a coin is easy to buy or sell. Trading volume is the better metric for that, meaning the value of all trades over a period, usually 24 hours. For Bitcoin, 24-hour volume on November 6 was around $45 billion, just under three percent of its market cap.

For some tokens the ratio is considerably worse. An analysis by cryptoticker.io from October 11, 2026 found that four of the 25 largest cryptocurrencies traded less than 0.32 percent of their market capitalization per day. What lies behind such cases is set out in the article on market cap and trading volume of the top 25.

A second problem is a small free float. If only a fraction of the tokens is freely tradable, a few purchases are enough to lift the price, and with it the market cap, sharply. The valuation of all units then follows a price based on very little volume. A high rank in the list can arise this way without much money having flowed into the token.

CoinGecko and CoinMarketCap: why rankings differ

If you compare a coin's market capitalization on two data sites, you will often find different values. There are several reasons for this. The providers source their prices from different exchanges and weight them differently. Above all, though, they set the circulating supply themselves: whether locked tokens, a foundation's holdings or burned coins are counted is decided by each site according to its own rules.

In practice, a single value is a snapshot with some blur, not an official figure. For large coins the differences are usually within a few percent; for small tokens they can be considerable. When buying, check what a stated circulating supply is based on and, if in doubt, consult a second source.

Market cap when buying: a MiCA-licensed exchange and the holding period in Germany

Market capitalization helps you assess a coin, but it does not make the buying decision for you. For investors in Germany, two further points matter when buying. Since the EU's MiCA crypto regulation took effect, providers that broker crypto assets in the EU need a license as a crypto-asset service provider. Which platforms hold such a license is shown in our crypto exchange comparison.

For tax purposes, cryptocurrencies held as private assets are subject to the holding period under Section 23 of the German Income Tax Act. If you sell a coin after more than one year, the gain is tax-free. Within that period, gains remain tax-free as long as all private disposal gains in a year stay below the exemption limit of 1,000 euros. This applies to Bitcoin just as it does to a small cap; the size of a coin plays no role.

Market cap: $2.58 trillion is a price tag, not a pile of money

The metric shows you in seconds how large a coin is relative to the market and guards against the fallacy of cheap unit prices. Three steps help you use it sensibly:

1. Gauge the size: Before every purchase, look up market cap, FDV and 24-hour volume, ideally in a tool that shows all three values. You will find a selection in the analytics platform comparison.
2. Choose a trading venue: Buy on a MiCA-licensed platform and check whether the coin trades there with sufficient volume. The providers are listed in the crypto exchange comparison.
3. Regularly rather than all at once: If you want to invest in the large assets without trying to time the market, you can buy with fixed monthly amounts. Providers and fees are shown in the Bitcoin savings plan comparison.
