Over the last 12 years, the cryptocurrency market share of Bitcoin ($BTC) has undergone substantial changes, ranging between a high of 99.1% in its initial years to a low of 31.1%. Since 2013, two-thirds of the days have seen daily Bitcoin ($BTC) dominance exceeding 50%, equivalent to approximately eight years of market dominance.

Bitcoin dominance has become less volatile as the market matured, with daily movements narrowing to a range of -1.2 to +1.6 percentage points.

Bitcoin shows a steady downvote of 93.3% in 2013 and 44.6% in 2018, which is five years of decline in a row by the annual averages. This decline changed in 2019, when it averaged 60.2, followed by 62.7 in 2020. Nevertheless, this number dropped once more to 47.6% in 2021 and 39.3% in 2022.

Bitcoin dominance is in an upward trend, with averages of 45.6, 51.9, and 59.3 to date, which occurred in 2023, 2024, and 2025, respectively. The present 2025 value is nearly equal to the 12-year average daily value of 62.5%. On April 7, 2025, dominance returned to a level higher than 60%, the first since March 15, 2021, with 60.5%.

Since February 2016, $BTC’s dominance has been less than 90 percent, with the rise caused by the growth of large altcoins, especially in 2017 during the ICO boom. On an analogous note, once hovering at 70.7% on January 3, 2021, it has not approached the 70% mark since then, which signals a more proportional allocation of Bitcoin and other digital assets.

As per CoinGecko report, $BTC has been dominating between 70% and above in only one-third of the aggregate period of the past 12 years. Moreover, its market share has been less than 60% slightly above 50% of the monitored period. Notwithstanding these changes, the recent increase is an indication of strength in the face of rising competition in the altcoin market.

As the $BTC bites off its daily volatility by a margin of up to -1.2 and +1.6 percentage points, the market seems to be maturing, maybe positioning to stabilize the dynamics of market shares in the coming decades.
