📊 Bitcoin Dominance BTC.D
The percentage of the entire crypto market's total value that belongs to Bitcoin alone. If the whole market is one pizza, dominance is how big Bitcoin's slice is next to every altcoin slice combined.
🍕 The simple version — Bitcoin's slice of the pie
Add up the value of every cryptocurrency in the world and you get the total market cap. Bitcoin dominance asks one question of that pile: how much of it is just Bitcoin? Take Bitcoin's market cap, divide it by the total, multiply by 100, and you have a percentage tracked under the ticker BTC.D. A market worth $3 trillion with $1.5 trillion of that in Bitcoin gives a dominance of 50%.
🧮 What moves the number
A coin's market cap is its current price × its circulating supply (the coins already mined and in people's hands). So dominance moves with two things at once: Bitcoin's price and the prices of every other coin. Bitcoin can sit perfectly still and its dominance can still shift, simply because the altcoins around it went up or down.
| What happens | What dominance does |
|---|---|
| 📈 Bitcoin rises faster than altcoins | Dominance goes up |
| 🚀 Altcoins rise faster than Bitcoin | Dominance goes down |
| 🟰 Bitcoin flat, altcoins fall | Dominance goes up (without Bitcoin moving) |
🧭 What people read into it
Traders watch dominance as a rough read on where money is leaning. Rising dominance often suggests people are favoring Bitcoin over riskier altcoins — a cautious, “risk-off” mood. Falling dominance can suggest a growing appetite for altcoins, the “risk-on” mood people call altcoin season. You will usually first meet the metric exactly there: in talk about whether altcoin season has started.
📊 It is a trend and positioning metric, not a price predictor. It describes how the market is leaning right now; it does not tell you what Bitcoin or any altcoin will do next.
🕰️ A short history of the number
Bitcoin held close to 100% dominance until around 2013, when the first altcoins appeared and started carving out slices of their own. Three moments since then moved the number noticeably: the 2017 ICO boom, the 2020–2021 bull market, and the 2024 launch of US spot Bitcoin ETFs. Each pulled money toward or away from Bitcoin relative to the rest of the market.
🚨 Things beginners should know
- 🔁 It is relative, not absolute — a falling slice does not mean altcoins are up; the whole market can be bleeding at once
- 🔢 No level is good or bad by itself — 60% is not bullish or bearish on its own; direction and context matter more than the raw figure
- 🔮 It does not predict price — it shows how the market is positioned, not where any coin goes next
- 📺 Where you will see it — the BTC.D ticker on TradingView, plus dominance charts on CoinMarketCap and CoinGecko
❓ FAQ
- If Bitcoin dominance is falling, are altcoins going up?
- Not necessarily. Dominance is a relative number — Bitcoin's share of the total. It can drop even while the whole market is losing value. If Bitcoin falls 10% and altcoins fall only 5%, Bitcoin's slice shrinks even though nobody made money.
- Where do I find the Bitcoin dominance chart?
- It is shown under the ticker BTC.D on TradingView, and on the dominance charts at CoinMarketCap and CoinGecko. Beginners usually run into it in conversations about 'altcoin season'.
- Does a high dominance number like 60% mean it is a good time to buy?
- No. A single level is not bullish or bearish on its own. Dominance describes how the market is positioned right now — it does not predict where any coin's price goes next. The direction and the wider context matter more than the raw number.
