Bitcoin dominance is a way to measure how big Bitcoin is compared to the rest of the crypto market.
Imagine the entire crypto market as a pie 🍰:
The slice that belongs to Bitcoin is its dominance.
The rest of the pie is all other cryptocurrencies (altcoins).
You can calculate it roughly like this:
Bitcoin Dominance (%) = (Bitcoin’s Market Value ÷ Total Crypto Market Value) × 100
For example:
Total crypto market = $2 trillion
Bitcoin market = $1 trillion
Bitcoin dominance = 50% → Bitcoin has half of all crypto money.
Why it matters:
1) If Bitcoin dominance rises
People are putting more money into Bitcoin than altcoins.
Usually happens when the market is cautious.
1) If Bitcoin dominance falls
Money is moving into altcoins.
Often a sign of an “altcoin season,” when smaller coins grow faster than Bitcoin.
In short:
Bitcoin dominance = Bitcoin’s share of the total crypto market.
