Altcoin cap hits $1.15T, ETH/BTC relative strength rises to 60.99, and Bitcoin dominance drops to 58%. Data confirms Q4 2025 altseason setup.

Altcoin Market Cap Hits ~$1.15T; ETH Outperforms BTC; Bitcoin Dominance Falls to 58%

The world market cap of altcoins is at an estimated level of 1.15 trillion as per the chart posted by ourcryptotalk. The chart indicates an escape out of the 1.0 trillion to 1.15 trillion support range that indicates an increase in the year 2025 at approximately 15 percent of the previous levels.

Ethereum strengthens versus Bitcoin

Ether has also performed well against the Bitcoin through relative strength index, which stood at approximately 60.99 as compared to low of 44 in mid-September. This is a 38.6 percent relative strength increase and the indicator that ETH is outshining BTC, which is a typical sign of investment flight to altcoins. The current dominance in Bitcoin has also reduced by 12.1 percent having been at 66 percent in the first half of the year and this shows that the money is leaving Bitcoin and going into the general altcoin market. The combination of these three signs creates a textbook structure of an altseason as the previous market cycles observed.

Altcoin market cap rises to ~$1.15 trillion (chart data)

In 2017, altcoin market cap increased 300 billion to 50 billion at the same time Bitcoin dominance decreased by 85 percent to 33 percent. In 2021, altcoins such as Solana and Cardano registered a skyrocketing rise as the altcoin market cap increased by 500 billion to 1.5 trillion and Bitcoin dominance dropped to 40 percent. The graphs included now are a reflection of those previous stages, and Ethereum is at the forefront. A 58 percent dominance in all crypto market value puts Bitcoin at 2.378 trillion Bitcoin market value and 1.722 trillion altcoin market value. That would imply the altcoin market might grow further by 50 percent to its current 1.15 trillion value provided the rotation persists.

Why these three factors matter together

The reasons behind this trend are increasing institutional flows into Ethereum spot ETFs with a net inflow of 234 million dollars on October 3, active DeFi, and seasonal Q4 rotations. ETH strength can be used as a leading indicator and a measure of confidence in further expansion of token markets. Traders anticipate a rally of large cap altcoins initially and smaller on a secondary level. The risks are still there since the Bitcoin dominance can turn around fast and regulatory news can change the mood, yet the combination of the three technical indicators of altcoin dominance increase, the power of ETH over BTC, and a declining Bitcoin dominance is the best rationale to support the altseason narrative at the end of 2025.
