Bitcoin Dominance (BTC.D)
What You’ll Learn
• What Bitcoin Dominance is
• How it’s calculated
• Why it matters
• How it affects altcoins
• How to use it in decision-making
What is Bitcoin Dominance?
Bitcoin Dominance = Bitcoin’s share of the total crypto market
Simple Idea:
If BTC.D = 50%
👉 Bitcoin = 50% of total crypto value
👉 It shows:
How much of the market is controlled by Bitcoin
The Formula
BTC Dominance = (Total Crypto Market Cap / Bitcoin Market Cap) ×100
👉 Key idea:
It’s a percentage, not a price
Example
If:
Bitcoin = $500B
Total crypto market = $1T
👉 BTC Dominance = 50%
Why BTC Dominance Matters

It shows where money is flowing:
BTC.D Rising
👉 Money is moving INTO Bitcoin
BTC.D Falling
👉 Money is moving INTO altcoins
👉 This is critical for strategy

When BTC Dominance Goes UP:
