Bitcoin dominance calculator
Work out Bitcoin's share of the whole crypto market from two market values, then see how that share would change if Bitcoin and every other coin moved by different amounts. Free, no sign-up, nothing leaves your browser.
The starting figures are the guide's simple example: a $2 trillion market with Bitcoin worth $1 trillion. Use today's figures from a data site you trust. This is a calculator, not a forecast or advice.
How it is worked out
Bitcoin dominance is Bitcoin's market value as a share of the whole crypto market. Data sites add up the market value of every coin they track and divide Bitcoin's market value by the total. Because each site tracks a different list of coins, their dominance figures can differ slightly.
What people read into it
Money moving from Bitcoin into other coins pushes dominance down, and in sell-offs holders often move into Bitcoin or stablecoins, which can push it up. Some traders treat falling dominance as a sign of an "altcoin season". It is a rough gauge of mood, not a forecast, and crypto prices can fall sharply whatever it shows.
