Bitcoin Dominance Declines to 60.4% as Ethereum and Altcoins Expand Market Share

Tracking the current market action at the time of press, CoinMarketCap data indicates that Bitcoin’s market dominance dropped to 60.4% on July 27, 2025, marking a 4.6% decrease over the past month. Ethereum increased its share to 11.8%, gaining 2.82% in the same timeframe. Meanwhile, the combined dominance of other cryptocurrencies climbed to 27.8%, reflecting a 1.77% month-over-month rise.

Compared to the previous day, BTC dropped slightly from 60.6%, while Ethereum increased from 11.6% to 11.8%. One week earlier, Bitcoin held 60.8% of the market share, Ethereum held 11.2%, and other assets totaled 28.0%.

Bitcoin’s highest dominance this year was 65.1%, recorded on June 27. Its lowest level was 53.9% on December 7, 2024. Ethereum’s yearly range spanned from 8.9% to 13.2%. Other cryptocurrencies reached a high of 32.9% and a low of 26.0% during the same period. The latest chart readings show Bitcoin’s dominance experienced sharp declines, followed by a gradual recovery. Ethereum and other assets recorded steady upward movements, indicating a redistribution of market share across crypto sectors.

Bitcoin Dominance Faces Breakdown as Key Support Zone Gets Retested

Despite the current market trend, an observation by Cryptoes reveals that BTC dominance has shown significant structural shifts over the past several months, moving away from a steady upward trend. After climbing steadily from mid-2023, BTC.D consistently formed higher highs while riding a blue ascending trendline. This trend remained intact until multiple rejections occurred near the 66% level, each marked with a visible price reversal.

The chart displays four rejection points at the same price level, forming a clear horizontal resistance zone. Each time dominance touched this range, it reversed sharply. These repeated failures at resistance indicate consistent selling pressure near the top of the channel. After the final rejection, the price broke below the trendline support, ending the long-term bullish structure.

Following the breakdown, BTC.D fell through a previously tested support near the 62% level. The chart shows a large red candle closing beneath this zone. This move shifted momentum to the downside. A red horizontal bar now marks the area as resistance. A crucial horizontal support near 60% has been retested several times before. If the price closes below it, further downside could follow. A projected move toward 54% is drawn with a white arrow. Until dominance climbs above the red resistance, the bearish formation remains intact.
