Dominance of Bitcoin in the cryptocurrency market is a key indicator that helps investors make decisions about portfolio allocation. As of January 15, 2026, BTC’s market capitalization reached 1931.90 billion dollars, and its share in the crypto market was 56.60%. This means that more than half of the total value of the cryptocurrency market is attributed to Bitcoin.

How the BTC dominance indicator works

When talking about Bitcoin dominance, it refers to the percentage ratio of BTC’s market capitalization to the total market capitalization of all cryptocurrencies. The calculation is simple: take the market value of Bitcoin, divide it by the total crypto market capitalization, and multiply by 100%.

In the history of cryptocurrencies, there was a time when BTC occupied 100% of the market — it was the only digital currency. With the emergence of Ethereum (2015 năm) and thousands of other altcoins, its share began to decrease. However, no project has yet managed to surpass Bitcoin in market value.

There is also the concept of “real dominance of BTC” — this is the ratio of currencies that use the proof-of-work consensus mechanism. This calculation includes Litecoin, Dogecoin, and Bitcoin Cash, providing a narrower comparison.

What drives changes in BTC dominance

Bitcoin dominance chart constantly fluctuates under the influence of several factors:

Market volatility — the main driver. Cryptocurrencies are characterized by high price unpredictability. If altcoins fall faster than BTC, Bitcoin’s dominance increases. Conversely, if the growth of altcoins outpaces Bitcoin, its share decreases.

Development of the altcoin ecosystem directly affects Bitcoin’s position. The more new projects and useful tokens appear, the more capital is diverted from BTC. This influence is especially noticeable when the popularity and price of altcoins grow.

Demand for stablecoins — another factor. When the market declines, investors withdraw funds from volatile assets and invest in stable coins pegged to the US dollar. USDT, USDC, and BUSD are becoming increasingly popular, especially during periods of extreme uncertainty. This increases their market share at the expense of BTC dominance.

Why traders use this indicator

Determining the altcoin season — the main application. When Bitcoin dominance falls, it signals that investors are actively buying altcoins. This period is called the “altcoin season.” It can be profitable for those catching trends in Ethereum, Shiba Inu, and other projects.

Assessing investor sentiment. Growing BTC dominance indicates a conservative approach — people are moving into safer assets. Falling dominance suggests risk appetite and demand for alternative assets.

Trading the dominance index. On major cryptocurrency exchanges, you can trade the index itself. For example, some exchanges offer the BTCDOM/USDT pair on the perpetual futures market. This allows speculation on the dominance indicator itself.

Forecasting extreme movements. Statistics show: when the dominance ratio is very high (for example, above 70%), BTC price often drops. Conversely, at low dominance (below 40%), there is a high probability of a sharp upward trend in Bitcoin.

How to use the dominance chart in trading

Investors monitor the Bitcoin dominance chart via TradingView or CoinMarketCap. These tools provide a visual representation of BTC’s strength relative to the rest of the market.

Practical approach:

• When dominance is rising — it’s wiser to hold positions in BTC or switch into it
• When dominance is falling — it may signal rotation into altcoins
• Extreme values (very high or very low) often precede trend reversals

However, it’s important to remember: Bitcoin dominance is not a signal to rely on alone. It should be combined with other technical indicators and fundamental analysis. Each such indicator provides only part of the market picture.

Is this indicator reliable for long-term decisions

Bitcoin dominance works well as a short-term market sentiment indicator. It reflects the relative strength of Bitcoin and shows where capital is moving in the crypto sector. It is indeed a useful tool for identifying market cycle phases.

But for the long term, caution is needed. The cryptocurrency market is constantly changing: new projects emerge, DeFi and other directions grow in popularity. As the altcoin ecosystem expands, Bitcoin’s share may continue to decline — this is a natural process of market diversification.

Nevertheless, Bitcoin remains the market anchor. Its market capitalization far exceeds any altcoin, so BTC will continue to be a key asset for portfolios. By using Bitcoin dominance chart together with other analytical methods, traders can better understand market dynamics and adjust strategies in a timely manner.

Frequently asked questions about BTC dominance

What does an increase in Bitcoin dominance mean? It indicates that investors are becoming more conservative and transferring capital into more stable Bitcoin, usually due to market decline or concerns about altcoins.

Where to find the current dominance chart? Charts are available on TradingView and CoinMarketCap. TradingView often offers more detailed analysis and tools for working with this index.
