$BTC $BNB $ETH

🧠 Overview

Bitcoin dominance—the percentage of total crypto market cap held by BTC—is a classic metric for understanding market cycles.

When BTC dominance rises or falls, it often signals major shifts in how capital flows between Bitcoin and altcoins.

Let’s explore what to watch for in 2025.

📊 1. What Is Bitcoin Dominance?

✅ BTC dominance = BTC market cap / total crypto market cap

✅ Shows if BTC is leading the market or if alts are gaining share

✅ Used by traders to time rotations between BTC and alts

Key rule: Dominance trends often predict altcoin performance.

---

📈 2. When BTC Dominance Rises

✅ Money flows into “safer” BTC during uncertainty

✅ Altcoins often underperform or bleed vs. BTC

✅ Common in bear markets or early bull market recoveries

Signal: Risk-off behavior, caution for alt-heavy portfolios.

---

📉 3. When BTC Dominance Falls

✅ Capital rotates into altcoins seeking higher returns

✅ Altcoin rallies (“alt seasons”) often coincide with falling dominance

✅ Usually happens mid-to-late bull markets when confidence is high

Opportunity: Good for rotating into strong alt projects.

---

🔎 4. Key Levels and Historical Context

✅ BTC dominance bottomed ~35–40% in previous alt seasons

✅ Tops ~70–75% during extreme BTC rallies or bear market fear

✅ Watch for breaks of trendlines or moving averages in dominance charts

Pro tip: BTC dominance is a macro signal—don’t overtrade it intraday.

⚠️ 5. What to Watch in 2025

✅ Bitcoin ETF inflows could support BTC dominance

✅ Strong narratives in Layer 2, RWAs, DeFi could shift capital to alts

✅ Macro conditions (interest rates, regulation) can move overall crypto allocation

Strategy: Balance your portfolio based on dominance trends, not just price hype.

---

✅ Conclusion

Bitcoin dominance remains a crucial indicator for crypto traders and investors.

In 2025, watching its trends will help you time rotations between Bitcoin and altcoins more intelligently.

Use it as part of a broader strategy to manage risk and maximize opportunities.
