Bitcoin, has long held a dominant position in the market. Its market dominance, the percentage of Bitcoin’s market capitalization compared to the total cryptocurrency market cap, has fluctuated over the years, but its influence on altcoin performance remains significant. In this article, we will explore the concept of Bitcoin market dominance, its impact on the altcoin market, and what it means for investors.

Understanding Bitcoin Market Dominance

Market dominance refers to the share a particular asset has in a given market. In the case of cryptocurrencies, Bitcoin’s market dominance is the ratio of its market capitalization (the total value of all existing Bitcoin) to the market capitalization of all cryptocurrencies combined. A high percentage indicates that Bitcoin is dominating the market, while a lower percentage shows a more diverse market with altcoins gaining traction.

A Brief History of Bitcoin Dominance

Since its inception in 2009, Bitcoin has held a substantial portion of the cryptocurrency market share. In the early years, it accounted for nearly 100% of the market due to a lack of competition. However, as more altcoins emerged, Bitcoin’s dominance began to decrease. The lowest it has been was during the peak of the 2017 bull market when it dropped to around 32%. Since then, Bitcoin dominance has fluctuated, but it remains a key factor in the overall performance of the cryptocurrency market.

Impact of Bitcoin Dominance on Altcoins

  1. Market Sentiment: Bitcoin dominance can provide valuable insights into market sentiment. A rising dominance indicates that investors are favoring Bitcoin over altcoins, signaling a possible shift towards a risk-averse environment. Conversely, a declining dominance suggests that investors are exploring altcoin opportunities and may be more willing to take risks.
  2. Market Cycles: Bitcoin’s dominance tends to follow a cyclical pattern, often correlating with market cycles. During bull markets, Bitcoin’s dominance may decrease as investors seek higher returns in smaller-cap altcoins. On the other hand, during bear markets, Bitcoin’s dominance typically increases as investors look for stability in the more established cryptocurrency.
  3. Liquidity: Bitcoin’s market dominance also affects the liquidity of altcoins. When Bitcoin dominates, it can be difficult for altcoins to gain traction, leading to lower trading volumes and price volatility. Conversely, when Bitcoin’s dominance wanes, it may signal a more favorable environment for altcoins, leading to increased liquidity and potentially greater returns.
  4. Innovation and Adoption: A decline in Bitcoin dominance could signal an increase in innovation and adoption of alternative blockchain projects. As altcoins gain market share, they may introduce new features, technologies, and use cases that could drive wider acceptance and adoption of cryptocurrencies.


Bitcoin market dominance plays a crucial role in determining the performance of the altcoin market. Understanding its impact can help investors make informed decisions about their cryptocurrency portfolios. As the cryptocurrency market continues to evolve, keeping a close eye on Bitcoin dominance will be essential for investors seeking to maximize returns and manage risk now, and in the future.
