Bitcoin Dominance: The Moment When the Leaders of the Crypto Market Are Determined

Let me briefly explain what Bitcoin dominance is.

In short, what is it?

BTC dominance refers to the percentage of Bitcoin's market capitalization in relation to the entire cryptocurrency market. For example, if the BTC market size is 1 trillion dollars and the total cryptocurrency market is 2 trillion dollars, then the dominance would be 50%.

A high ratio = Bitcoin is strong, a low ratio = a festival for altcoins is a good image.

How to calculate

It's simple:

BTC Dominance = ( Bitcoin market capitalization ) ÷ ( total market capitalization ) × 100%

The price fluctuations of BTC directly affect this score. If BTC rises and altcoins stagnate, dominance will automatically increase.

Four Common Scenes

When dominance rises

1. Investors sell altcoins & increase BTC purchases
2. Altcoin prices are declining, while BTC prices remain strong.
3. Funds concentrate in BTC due to risk aversion (during market panic)
4. Institutional investors purchase BTC through the institutionalization of BTC ETFs and other mechanisms.

When dominance decreases

1. Investors selling BTC & buying altcoins
2. Altcoin prices surge
3. The market becomes risk-on (latter half of a bull market)
4. New themes emerge (DeFi, NFT, AI token era, etc.)

What Can Be Seen in Numbers

BTC dominance > 50% = Bitcoin occupies more than half of the market. BTC is in a king state. Other cryptocurrencies have little chance to shine.

BTC dominance < 40% = Entering the altcoin era. Funds are flowing into ETH, SOL, and emerging projects. It's the age of selecting individual tokens.

Note: Do not make judgments based solely on this.

Common misconception: “When dominance decreases, altcoins rise.”

No. A decrease in dominance only indicates that the value of altcoins has increased relatively, and it does not necessarily mean that there are absolute profits. If the entire market is declining and “BTC falls even further,” then dominance may decrease, but altcoins might also be incurring losses.

Trader's Perspective

The reason to look at dominance is to read market psychology.

• Dominance Uptrend → Conservative market sentiment. Flight to safe assets (BTC).
• Dominance Downtrend → Bullish sentiment. Time for risk-oriented investors to move.

By reading this signal, you can predict which stock is likely to move next.

Relationship with Bitcoin Halving

The market tends to experience increased volatility around the Halving. As a result, dominance often fluctuates significantly in the short term. It is essential to keep an eye on the Halving events.

Key Point: BTC dominance is a barometer of the market. The movement of the numbers can indicate when the next trend reversal might occur. However, do not make judgments based on this alone. It only has meaning when combined with other indicators.
