How is Bitcoin dominance calculated?
What influences Bitcoin dominance?
The Bitcoin dominance index (or BTC.D ) shows how much of the total money invested in the crypto market is directed toward Bitcoin. On this page, in the upper left corner, there is a pie chart where we have tried to visually represent Bitcoin dominance compared to other cryptocurrencies — or as users call them, altcoins.
Think of the crypto market as a pie, and if Bitcoin dominance is 50%, it means that half of the pie belongs to Bitcoin, while the other half is shared among other digital currencies such as Ethereum, Solana, XRP, Dogecoin, and others.
To properly understand this index, we can imagine that when it is at 0%, no money is invested in Bitcoin — in that situation, all capital is in altcoins. If dominance approaches 100%, it means that virtually all money in the market is directed toward Bitcoin.
This indicator carries strong significance for investors, as it provides an overview of market dynamics. This metric is used to identify moments when investors stop putting money into Bitcoin (BTC.D falls) and instead invest in other digital currencies. Of course, by following this index, things can also work the other way around.
The calculation behind the dominance of a cryptocurrency is fairly straightforward: the market capitalization of each cryptocurrency is taken, and then each one s share of the total crypto market capitalization is determined.
This may be difficult to understand without knowing the underlying terms, but each one is explained in detail below.
The market cap of a cryptocurrency is calculated simply:
(number of coins in circulation) × (current price of one coin) = market capitalization
Example market cap calculation — Bitcoin
- Current number of Bitcoin in circulation: 19,000,000 BTC (19M)
- Price of one BTC: $100,000 (100K USD)
- Calculation: 19,000,000 × 100,000 = $1,900,000,000,000
- Total Bitcoin market cap: $1,900 billion (1.9T USD)
The market cap of all cryptocurrencies combined is calculated as follows (example):
- Bitcoin: 19 million BTC × $100,000 = $1,900 billion
- Ethereum: 120 million ETH × $2,500 = $300 billion
- Ripple (XRP): 50 billion XRP × $0.60 = $30 billion
- Other cryptocurrencies: approximately $170 billion
Total crypto market capitalization:
1,900 + 300 + 30 + 170 = $2,400 billion
How BTC dominance is calculated (example)
BTC.D = (total Bitcoin market cap) / (total crypto market cap) × 100
BTC.D = 1,900 / 2,400 × 100 = 79.16%
Applying the same formula, we can determine the dominance of other cryptocurrencies such as Ethereum (ETH.D), Ripple (XRP.D), or Solana (SOL.D).
The main factors that influence Bitcoin dominance are:
- News and investor sentiment;
- Altcoins gaining popularity and trust;
- Pro-crypto regulations;
- Events with macroeconomic impact;
- Technological advancement in cryptocurrencies.
These factors can influence market dynamics and trigger major shifts. Each reason why Bitcoin dominance rises or falls is explained in detail below.
1) News and investor sentiment
Bitcoin investors — both institutional (investment funds, private companies, or financial institutions) and individuals — are sensitive to positive or negative news. Sometimes this news isn t necessarily an objective reason for investors to make a decision, but FOMO during price surges or panic during drops often takes hold. These emotions can lead to very sudden drops or almost inexplicable rises.
Examples of positive news that drove investors to rush into buying Bitcoin include:
- Donald Trump s announcement to create a federal Bitcoin reserve;
- Israel s announcement pledging a proactive approach to blockchain and cryptocurrency adoption over the next 10 years;
- Tesla accepting Bitcoin as a payment method for purchasing their electric vehicles.
Examples of negative news that created panic in the market, leading to sharp price drops and many investors pulling out:
- Hacks of cryptocurrency exchanges such as Mt.Gox or ByBit;
- Jamie Powell s announcement about the Federal Reserve s lack of interest in creating a Bitcoin reserve.
2) Altcoins gaining popularity and trust
While Bitcoin dominance remained above 90% consistently between 2009 and 2017, the growing adoption of cryptocurrencies like Ethereum, Solana, Ripple, Litecoin, Stellar, and Bitcoin Cash caused that share to begin declining. Bitcoin was no longer as dominant in the market — investors started looking toward other technological innovations in the space.
New communities emerged, new cryptocurrencies solved problems that Bitcoin couldn t address as efficiently, and many investors wanted to catch an upward trend similar to what Bitcoin had been. This caused the market to divide.
In 2017, Ethereum held approximately 25% of all capital invested in the crypto market. That figure has since declined as similar technologies emerged and market dynamics shifted. In recent years, this index has not exceeded 20%.
3) Pro-crypto regulations across multiple countries
On June 17, 2025, the United States enacted a law called the Genius Act, which regulates cryptocurrencies. Additionally, with Donald Trump s arrival at the White House, he announced his support for cryptocurrency adoption and has publicly stated multiple times that he is a major fan of this sector and wants the US to lead global crypto adoption.
Another country that stood out for the speed of its acceptance of these technologies is El Salvador. They announced as early as 2021 that Bitcoin is legal tender — a huge step for Bitcoin adoption and a direct signal of acceptance in an environment that was deeply resistant to change.
In most developed countries, clear legislation already exists to provide a legal framework for cryptocurrency exchanges and software companies developing such technologies. In the European Union, a legal framework called MiCA has been implemented, requiring all virtual currency providers and exchanges to obtain licenses in order to offer such services.
These regulations have also brought big players into the cryptocurrency market — investment funds have started putting very large sums of money into Bitcoin and altcoins. MicroStrategy recently announced that they have surpassed 700,000 BTC acquired and have no plans to stop.
Starting in 2024, the first spot Bitcoin ETFs (Exchange Traded Funds) were approved in the US, meaning institutions can now invest directly in Bitcoin through regulated, exchange-listed products.
4) Events with macroeconomic impact have influenced Bitcoin dominance
The COVID-19 pandemic, the start of the Russia-Ukraine war, inflation rates, rising interest rates, and many other global events have had a direct impact on Bitcoin dominance and on cryptocurrency investments.
The market is divided on this: many see Bitcoin as a risky investment with very high growth potential, and these are not the investors who tend to hold cryptocurrencies when a global event occurs. They view it as a nice to have investment and are not part of the core Bitcoin community.
On the other hand, there is a core group of users who, regardless of macroeconomic conditions, support Bitcoin adoption — having a direct impact on BTC dominance.
5) Technological advancement in cryptocurrencies — an important factor for Bitcoin dominance
Innovations aimed at improving the scalability, efficiency, and security of the Bitcoin network play a significant role in the evolution of BTC dominance. The faster, more accessible, and more secure Bitcoin becomes, the more attractive it is to users and investors — which drives its share of the crypto market upward.
Relevant examples of recent technological developments:
- Lightning Network — a layer 2 solution that enables near-instant microtransactions with extremely low fees. This increases Bitcoin s practical utility for everyday payments, not just as a store of value. As more apps and wallets integrate Lightning, adoption grows and BTC dominance consolidates.
- Segregated Witness (SegWit) — a technical upgrade that optimizes how data is stored in blocks. By reducing the size of each transaction, more can be processed within the same block, increasing network efficiency.
- Taproot Upgrade — an improvement that adds more privacy and functionality for smart contracts, making the Bitcoin network more versatile. This upgrade opens new possibilities for decentralized applications and improves user identity protection.
These innovations have created a different perception of Bitcoin. If initially it was talked about only as digital gold — an asset to be stored that was not competitive with existing financial systems — many now see it as an easily transactable asset, at low cost and highly efficient. Physical and online stores have begun adopting it as a payment method for goods and services, and this is directly reflected in Bitcoin s dominance over other cryptocurrencies.
Bitcoin s role in the crypto market
What do investors say?
Historical overview
Understanding Bitcoin dominance in the crypto market is very important because it helps investors see an overall picture of fluctuations in this sector and market trends. It can reveal opportunities or help reduce risk.
By understanding this metric, the following can be observed:
1) Understanding current market dynamics
By consistently tracking this index, you can see where most investors prefer to put their money or where the most capital is concentrated. For example, when BTC.D rises day after day, or over a longer period of time, you can conclude that most investors believe Bitcoin is stable and a good investment relative to other cryptocurrencies.
2) Altcoin season
When Bitcoin's market dominance falls, it's clear that investors find it more opportune to move toward other cryptocurrencies like ETH, SOL, DOGE, or other popular digital currencies. However, this is not a clear signal that another cryptocurrency will necessarily rise — a shift in market cap weighting does not automatically translate into price increases for other cryptocurrencies.
Historically, there have been moments (rare ones) when BTC.D fell and ETH.D rose, but this didn t always materialize into a price increase.
3) Bitcoin bull market season
There have been moments when many investors bet that Bitcoin was about to have a "bull run" simply by closely watching its share of market capitalization. Almost every consolidation at the price level, or an upward trend, was preceded by an increase in BTC.D.
One of the most respected veterans in the market, Peter Brandt, stated that a drop in Bitcoin dominance below the 63% threshold is a clear signal that we are in the middle of altcoin season — the period when cryptocurrencies like Ethereum, Solana, Ripple, and others start gaining ground and capital from Bitcoin.
"It's a major signal for altcoin season," Brandt said, noting that this dynamic has also been observed in previous market cycles.🔗 Read the full article here
Analyst Matthew Hyland reinforced the idea, stating that Ethereum s positive performance could push Bitcoin dominance lower:
If Ethereum continues to break upward and remains bullish against BTC, there s a 99% chance Bitcoin dominance has already peaked, he wrote in a post on X (formerly Twitter).
It s practically impossible for BTC dominance to keep climbing if ETH continues to appreciate against Bitcoin.
The same trend is noted by the Abarai team, which highlights a clear correlation between the price of Bitcoin and its dominance.
In transactions with our clients, we clearly see how investor behavior shifts depending on this dominance. When Bitcoin dominance is stable or rising, most people buy Bitcoin. But when we see a drop in Bitcoin dominance, purchase volumes in altcoins increase.
A drop in BTC dominance is not just a technical indicator — it s a signal of shifting risk appetite in the market.
- Bitcoin is seen as the safe asset in crypto.
- Altcoins come with potentially higher returns, but also increased risk.
- When capital starts flowing toward them, it means investors are becoming optimistic and taking on more risk.
Bitcoin, considered today the king of cryptocurrencies, emerged in a special context — within a community of digital activists known as Cypherpunks. They promoted the idea of privacy, cryptography, and financial freedom in an increasingly digitally controlled world. They feared that as money became digitized, governments would gain total control over ordinary people s finances.
The first Bitcoin transaction took place between Satoshi and Hal Finney in 2009 — a test transaction. The first transaction with economic purpose was made in 2010, when a programmer named Laszlo Hanyecz paid 10,000 BTC for two pizzas, placed through an online forum.
Period 2010 – 2015
During this period, Bitcoin dominance was consistently above 95%. The share of investment in Bitcoin was almost total — fairly easy to understand why. Cryptocurrencies like Ethereum or Solana didn t appear until 2015 and 2020 respectively. Bitcoin was promoted on various forums and was the first cryptocurrency that proved its effectiveness.
During these years, Bitcoin experienced several bull runs — one in 2011 and another in 2013. Despite price fluctuations, throughout this entire period Bitcoin dominance in the crypto market remained constant (above 95%) because there weren t many alternatives, and blockchain technology and decentralized systems were slowly making their way into the market.
Period 2015 – 2018
Bitcoin dominance in the cryptocurrency sector recorded a significant decline — the largest drop in the entire history of BTC.D — from approximately 95% down to 35%. Several factors contributed to this, some of which are explained below.
Causes of the decline in Bitcoin dominance:
- The launch of multiple new cryptocurrencies competing with Bitcoin
Dozens or even hundreds of new projects were launched, some with innovative technologies. Ethereum introduced smart contracts, while others promised scalability, privacy, or blockchain infrastructure solutions. They either wanted to complement Bitcoin s technology or came as complementary solutions for other projects and applications. - The ICO craze
Many investors who hadn t initially invested in Bitcoin redirected their attention toward new projects promising very high returns. This is how ICOs emerged — Bitcoin dominance inevitably suffered, as people were saying they wouldn t achieve the same consistent returns. Some risk-tolerant investors wanted to put money into new projects that could bring them 10x, 25x, or even 100x gains.
Bitcoin s price behavior during this period:
Although dominance fell, the price of Bitcoin rose considerably. In December 2017 it reached an all-time high of nearly $20,000. This shows that dominance doesn t only fall when Bitcoin loses value — it falls especially when other cryptocurrencies appreciate at a faster pace.
Period 2018 – 2025
This period had a completely different character for the crypto world. Bitcoin dominance began to stabilize as major financial institutions entered the space, and fluctuations were no longer as large as in the 2015–2018 period. Whereas that earlier period saw fluctuations of approximately 60% (between the maximum and minimum of dominance), during this period Bitcoin dominance saw fluctuations no greater than 25% for almost the entire stretch.
Analysis strategies
7 mistakes with Bitcoin dominance
Bitcoin Dominance (BTC.D) is a key indicator that offers valuable clues for optimizing investment decisions. Specifically:
- A phase of rising Bitcoin dominance (BTC.D increasing) typically indicates a period of market uncertainty or the beginning of a bullish cycle. Capital tends to flow into Bitcoin, considered the safest crypto asset at that moment.
- A phase of falling Bitcoin dominance (BTC.D decreasing) often signals an "Altcoin Season" or a period of market euphoria, where altcoins outperform Bitcoin. Capital moves from BTC into other cryptocurrencies — more volatile, but with faster growth potential.
Strategic rotation in practice
Investors use this dynamic to maximize profits:
- Buy Bitcoin when the market is uncertain or in a "recovery" phase (BTC dominance rising).
- Buy altcoins when Bitcoin dominance reaches a peak and starts declining (signaling an "Altcoin Season").
- Sell altcoins when Bitcoin dominance reaches a bottom and starts rising again (signaling a potential correction or end of a bull market).
HODLing (Hold On for Dear Life)
HODLing is one of the simplest strategies for beginners and involves buying Bitcoin with the intention of holding it long-term (ignoring price fluctuations). Investors buy Bitcoin and hold it for months or even years, regardless of daily market movements. Michael Saylor of MicroStrategy and large institutions that have invested in Bitcoin long-term demonstrate the effectiveness of this approach.
Advantages
- First and most important: simplicity. You don t need to monitor charts daily or perform complex technical analysis. Transaction costs are minimal, since you buy once and hold.
- Psychological stress is reduced compared to other strategies. You don t worry about daily fluctuations and don t risk panic-selling at the first sign of a dip.
Risks
- You need patience and the ability to resist the temptation to sell when the market falls.
- You cannot profit from short-term fluctuations to increase your gains. If Bitcoin drops 50%, you hold your position and wait for recovery.
If you re a HODLer and Bitcoin dominance is rising, you might consider it a good moment to maintain or even increase your Bitcoin position. This is based on the premise that Bitcoin will continue to consolidate its leadership position and deliver the desired long-term returns.
Day Trading
Day trading involves buying and selling Bitcoin or other cryptocurrencies multiple times within the same day, with the goal of generating income by capitalizing on very short-term price movements.
Bitcoin Dominance provides a range of important information, indicating where capital is located and which type of assets are favored at any given moment.
Note: Day trading requires hours spent in front of a computer and real-time monitoring of crypto markets.
Advantages of Day Trading
- The potential for quick profit is attractive. Skilled traders can generate consistent daily income from Bitcoin's volatility.
- You are not exposed to long-term risks. Your position closes every day, so you don't worry about what happens overnight or over the weekend.
- You can profit from both upward and downward price movements in the market.
Risks of Day Trading
- Psychological stress is extreme. Quick decisions and potential losses can affect mental health and judgment.
- Transaction costs accumulate quickly. Commissions from dozens of daily trades can significantly erode profits.
- The failure rate is high. Statistics show that the majority of day traders lose money over the long term.
How day traders can use Bitcoin Dominance
Identifying the general market sentiment:
- BTC.D rising rapidly: If Bitcoin dominance rises sharply, even on a short timeframe (for example, a 1–4 hour chart), this can signal risk aversion in the market. What will a day trader do? They will interpret this as a signal to quickly close open positions in altcoins or to look for short positions on altcoins / long positions on BTC.
- BTC.D falling rapidly: A sudden drop in Bitcoin dominance indicates an increase in risk appetite. Capital is aggressively moving toward altcoins. This is an opportunity for day traders to look for altcoins with rapid growth potential and open long positions on them — or even short Bitcoin if its price stagnates or falls while altcoins explode.
Choosing the trading instrument (Bitcoin vs. Altcoins):
- High/rising dominance: Day traders will focus more on Bitcoin trades during these periods.
- Low/falling dominance: This is "altcoin hunting" time. Day traders will look for the best opportunities in altcoins, as these can offer much larger percentage price movements than Bitcoin in the short term.
Confirming technical signals:
- A day trader never relies on a single indicator alone. Bitcoin Dominance can act as a filter or confirmation for other technical analyses (support/resistance, volume, RSI, MACD, etc.).
- For example, if a trader sees a buy signal on an altcoin but Bitcoin dominance is rising rapidly, they might be more cautious or delay entry, knowing the market currently favors Bitcoin. Conversely, a buy signal on an altcoin confirmed by falling Bitcoin dominance could increase confidence in the trade.
Risk management:
- During periods when Bitcoin dominance is very high or very low and approaching historical extremes, day traders can anticipate a reversal.
Concrete Day Trading example based on BTC.D:
Suppose a day trader observes the following:
- The Bitcoin Dominance (BTC.D) chart on a 1-hour timeframe breaks a key support level and starts falling sharply.
- At the same time, the price of Bitcoin is relatively stable or even slightly declining.
- The trader then looks for altcoins with rising volume and signs of accumulation on their 5- or 15-minute charts.
- They find an altcoin that has just broken an important resistance level with high volume.
- The trader opens a long position on that altcoin, setting a tight stop-loss below the broken resistance and a take-profit at the next resistance level.
- As Bitcoin dominance continues to fall, the altcoin in question continues to rise, and the trader closes the position in profit.
Bitcoin Dominance is a powerful tool, but like any tool, it can be misused. Here are 7 common mistakes you can make when relying on BTC dominance for your investment decisions:
1. Focusing exclusively on Bitcoin dominance
You should never rely solely on Bitcoin dominance for your investment decisions. Bitcoin dominance doesn t tell you everything about the market. You can have stable Bitcoin dominance while altcoin prices are falling. Always correlate dominance with trading volume and the general market trend.
2. Ignoring market context
Another common mistake is analyzing Bitcoin dominance in isolation, without taking the broader crypto market context into account. Dominance can vary significantly depending on the phase of the market cycle. In bull markets, drops in Bitcoin dominance are normal and healthy. In bear markets, rising dominance often indicates a flight to safety. Understanding this context is essential for accurate interpretation.
3. Avoid emotional reactions to rapid market changes
Bitcoin dominance can fluctuate rapidly in the short term, and emotional reactions can lead to poor investment decisions. It s important to distinguish between temporary changes in volume or prices and sustained trends.
4. Underestimating the impact of new listings
When new cryptocurrencies are listed on the market, they can artificially influence Bitcoin dominance. This can create the impression of a drop in Bitcoin dominance when, in reality, nothing significant has happened. Tip: always follow news about major new listings and try to understand whether changes in dominance are organic or artificial.
5. Neglecting seasonal factors
Crypto markets operate in cycles. Bitcoin dominance behaves differently in a bull market compared to a bear market. For example, in a bull market, falling Bitcoin dominance may signal a thriving altcoin season. In a bear market, rising Bitcoin dominance may indicate a "flight" to the relative safety offered by Bitcoin, even as it too declines. The crypto market often exhibits seasonal patterns that can influence Bitcoin dominance.
6. Using the wrong time intervals
Choosing the right time interval for analysis is extremely important, because using intervals that are too short generates false signals. On the other hand, intervals that are too long can cause you to miss important opportunities.
7. Unrealistic expectations
Many investors make the mistake of treating Bitcoin dominance as a crystal ball that can predict the next big market move. Use Bitcoin dominance together with multiple indicators when building a strategy.
Conclusion
Bitcoin dominance continues to be a relevant indicator for the crypto market, and understanding it can give informed investors a competitive advantage.
