Altcoin Season? Ether Beats Bitcoin as BTC Dominance Holds

• ETH gained nearly 29% in seven days, outpacing Bitcoin’s 23% weekly advance.
• Bitcoin dominance held near 59.7%, keeping a full altcoin rotation unconfirmed.
• CoinMarketCap’s Altcoin Season Index stood at 37, well below its 75 threshold.

Altcoin-season expectations are strengthening after smaller cryptocurrencies posted their sharpest weekly rebound in months, yet the market still lacks confirmation of a broad rotation. Analyst Ash Crypto noted that the market capitalization of cryptocurrencies outside the top 10 jumped roughly 23% last week, highlighting a sharp improvement in risk appetite.

That momentum was also visible across broader market gauges. TradingView’s OTHERS index gained about 19% over seven days on Aug. 26, while TOTAL3, which excludes Bitcoin and Ether, advanced roughly 15%. 

However, the OTHERS-to-Bitcoin ratio fell about 1.9% during the week, showing that much of the rebound still occurred within a BTC-led market. That distinction matters as rising dollar prices alone do not establish altcoin season. CoinMarketCap’s Altcoin Season Index remained at 37 out of 100.

The platform defines altcoin season when 75% of eligible top-100 coins outperform Bitcoin over 90 days, a threshold current market breadth has not reached. The contrast leaves the market in a transition phase, with breadth improving faster than relative performance against the largest cryptocurrency for now.

Bitcoin Dominance Near 60% Keeps Altcoin Rotation Incomplete

Bitcoin remained the largest force in the market, with dominance near 59.7% and a weekly price gain of about 23%. BTC traded around $78,200 to $79,300 on Wednesday after briefly moving above $80,000, while U.S. spot ETFs recorded $314 million in Tuesday inflows.

Those inflows pushed August totals above $3 billion, reinforcing the scale of demand supporting the market’s leading asset. Price structure also keeps attention on the $80,000 level, which remains immediate resistance, followed by $82,000 and $85,000.

A sustained hold above the earlier $76,000 breakout zone would preserve the current structure, while $73,000 marks the deeper level tied to the Aug. 20 breakout. As long as dominance stays close to 60%, smaller tokens remain dependent on whether capital begins rotating away from Bitcoin rather than simply rising alongside it.

Ethereum’s 29% Weekly Gain Strengthens the Altseason Signal

Ethereum, on the other hand, provided the clearest evidence of improving rotation. ETH traded near $2,456 after gaining almost 29% in seven days, outperforming Bitcoin’s weekly advance.

The ETH/BTC ratio also climbed near 0.0313 and reached roughly 0.0321 during the week, showing stronger relative performance against the market leader. CoinMarketCap identifies stronger Ethereum performance as a common stage before capital spreads further into smaller cryptocurrencies.

Even so, the market has not crossed the platform’s formal altcoin-season threshold, and Bitcoin still controls nearly three-fifths of total capitalization. Ethereum’s immediate test sits near $2,500, while $2,250 remains the level associated with last week’s breakout.

The data therefore points to early rotation rather than a completed market shift. Smaller assets are recovering, and Ethereum is leading Bitcoin on weekly performance.

However, BTC dominance remains the deciding constraint. A confirmed altcoin season would require broader relative outperformance, not only stronger dollar gains across smaller tokens.
