Bitcoin dominance is Bitcoin's percentage of the cryptocurrency market capitalization counted by a data provider. It compares BTC's market cap with a total that includes BTC itself. A rising percentage means Bitcoin accounts for a larger share of that measured total; it does not necessarily mean Bitcoin's price is rising. CoinGecko's definition
How Bitcoin dominance is calculated
The calculation uses circulating market capitalization:
BTC market cap = BTC reference price × BTC circulating supply.
Bitcoin dominance = BTC market cap ÷ total included crypto market cap × 100.
The denominator includes Bitcoin as well as the other eligible assets. If BTC has a market cap of $1.20 trillion within a $2.00 trillion total, its dominance is 60%. Dividing by only the remaining $0.80 trillion would answer a different question: Bitcoin's size relative to the rest of the market, rather than its share of the whole. CoinMarketCap's dominance definition
Use compatible inputs from the same provider and snapshot. A circulating-market-cap calculation uses circulating supply, not the maximum number of coins that might exist. CoinMarketCap states its market-cap formula as reference price multiplied by circulating supply. The distinction from fully diluted valuation is explained in the market cap and FDV guide. CoinMarketCap's capitalization methodology
What is included in the total?
“Total crypto market cap” means the total within the chart's definition, not necessarily every token ever created. Check the provider's coverage and exclusions before comparing percentages.
Stablecoins are included in CoinMarketCap's standard Bitcoin-dominance chart. CoinGecko also counts stablecoins within its overall crypto total. That matters because stablecoin market cap can change even when Bitcoin's price does not. A chart excluding stablecoins measures a different share and should say so explicitly.

Providers also need to address double-counting. CoinGecko excludes crypto-backed wrapped, bridged and staked tokens from its global total so that representations of an underlying asset do not count its value again. You therefore cannot reproduce that total simply by adding every token displayed on the site. CoinGecko's global chart methodology
Chart coverage can be narrower for other reasons. TradingView defines its TOTAL series as the market capitalization of its top 125 cryptocurrencies, and BTC.D as Bitcoin market cap divided by that TOTAL, multiplied by 100. Read the symbol's definition rather than treating every chart labelled “dominance” as the same dataset. TradingView's chart definitions
Two examples where dominance and price move differently
The following figures are hypothetical, not current market data. All amounts are in US dollars. Assume BTC circulating supply stays fixed at 20 million BTC, the provider includes the same assets throughout, and there are no supply-data revisions. The two scenarios each start from the baseline; they are not consecutive periods.
| Input or result | Baseline | Stablecoin market cap grows | BTC and other non-stablecoin assets fall |
|---|---|---|---|
| BTC price | $60,000 | $60,000 | $54,000 |
| BTC circulating market cap | $1.20 trillion | $1.20 trillion | $1.08 trillion |
| Other non-stablecoin market cap | $0.60 trillion | $0.60 trillion | $0.42 trillion |
| Stablecoin market cap | $0.20 trillion | $0.40 trillion | $0.20 trillion |
| Total included market cap | $2.00 trillion | $2.20 trillion | $1.70 trillion |
| BTC dominance | 60.00% | 54.55% | 63.53% |
Stablecoins grow while Bitcoin's price stays unchanged
The BTC price and circulating supply are unchanged, so its market cap remains $1.20 trillion. Stablecoin market cap rises by $0.20 trillion, increasing the total to $2.20 trillion:
$1.20 trillion ÷ $2.20 trillion × 100 = 54.55%, rounded to two decimal places.
Bitcoin's dominance falls by about 5.45 percentage points, from 60.00% to 54.55%, without a fall in its price. This example does not establish that anyone sold BTC. It changes the size of the denominator while keeping the BTC inputs fixed.
Bitcoin's price falls while its dominance rises
Restart from the baseline. BTC falls from $60,000 to $54,000, a 10% price decline. With circulating supply fixed, its market cap falls by 10% too, to $1.08 trillion. Other non-stablecoin market cap falls from $0.60 trillion to $0.42 trillion, while stablecoins remain at $0.20 trillion.
The new total is $1.08 trillion + $0.42 trillion + $0.20 trillion = $1.70 trillion:
$1.08 trillion ÷ $1.70 trillion × 100 = 63.53%, rounded to two decimal places.
Bitcoin now represents a larger share of a smaller total. Dominance rises by about 3.53 percentage points even though a BTC unit is worth 10% less in dollars. Percentage points describe the change between the two dominance readings; they are not Bitcoin's price return.
What rising or falling dominance tells you
With a consistent asset universe and methodology, rising dominance means BTC's market cap grew faster, or fell less, in percentage terms than the combined market cap of the other included assets. Falling dominance means the reverse. The comparison concerns the aggregate, so it need not describe every non-Bitcoin asset.
Neither direction establishes the next BTC price move. The examples also show why a fall in dominance does not automatically confirm an “altcoin season”: a larger stablecoin market cap can lower Bitcoin's share without other non-stablecoin assets gaining value.
Market capitalization is a price-times-supply valuation. Its change is not a ledger of cash deposited, withdrawn or transferred between assets. A change in dominance alone therefore cannot prove that investors moved a particular amount of money from Bitcoin into altcoins. It also says nothing about how much you could sell at the displayed price.
Treat dominance as context for a relative-size question. A buy or sell decision would need separate evidence about the asset, price, timeframe, liquidity and risk; the ratio supplies no automatic trading rule or return forecast.
Why two providers can show different percentages
Even when both charts include Bitcoin in the denominator, their inputs may differ:
- Asset coverage. Eligible projects, exclusions and the treatment of linked representations determine which market caps enter the total.
- Price calculation. CoinGecko filters anomalous market quotes and uses volume weighting. CoinMarketCap also processes exchange-market inputs and excludes unsuitable prices. The reference price is not necessarily the last trade on one exchange.
- Circulating supply. CoinGecko describes checks using project information and blockchain explorers. CoinMarketCap treats circulating supply as an estimate of public float and may exclude insider-held allocations even when they are technically unlocked.
- Snapshot time. A numerator taken from one moment and a denominator from another need not reproduce the provider's displayed ratio.
The price and supply policies are documented in CoinGecko's methodology, CoinMarketCap's price methodology and CoinMarketCap's supply methodology.
These differences explain why you should check definitions; they do not identify the cause of any particular gap between two live readings. That would require their actual inputs at the same time. An asset addition, exclusion or supply-data revision can also change a measured share without representing a BTC price move.
A quick way to read a dominance chart
- Identify the provider and series. Check whether stablecoins are included, which assets the total covers, and whether the methodology has changed.
- Match the timeframe. Compare the dominance change with BTC's price change over the same interval and in the same quoted currency.
- Inspect both sides of the ratio. Look at BTC market cap and the included non-BTC total, not just the percentage line.
- Keep the conclusion specific. Say Bitcoin's measured market-cap share rose or fell. Do not turn that observation into an investor count, cash-flow estimate or price forecast.
For a simple dominance comparison over time, staying with one consistently defined series avoids mixing different denominators. Keep the provider, timestamp and any stablecoin exclusion beside the number when you share it.
Common questions
Does 60% dominance mean 60% of crypto investors own Bitcoin?
No. It describes a share of included market capitalization, not a share of people, wallets or transactions. The formula contains no investor count.
Is Bitcoin dominance the same as Bitcoin's price?
No. Price is the value quoted for one BTC. Dominance is a percentage comparing Bitcoin's market capitalization with a wider total. In the second example, BTC's price falls 10% while dominance rises to 63.53%.
Is there a good or bad Bitcoin dominance percentage?
The calculation does not set a desirable level. A 60% share describes a particular total at a particular time; it does not establish whether BTC is cheap, expensive, safe or likely to rise. Compare the same series over time and examine the inputs before interpreting a change.
Where can you check current Bitcoin dominance?
CoinGecko and CoinMarketCap publish dominance charts. Check the displayed timestamp and methodology. The 60.00%, 54.55% and 63.53% figures in this guide are hypothetical examples, not current market readings.
A dominance reading does not answer a short-term price question. Read the specific market rules, eligibility conditions and risks before participating.
