Bitcoin Dominance Tests 61% Breakout, and That's Bad News for Altcoins

Bitcoin is falling, but altcoins are falling even faster. Bitcoin dominance, which measures Bitcoin’s share of the total cryptocurrency market, has climbed to 60.98%, its highest level since May 2026.

The figure is approaching a critical turning point. If dominance breaks above 61%, altcoin investors could face another period of underperformance.

Bitcoin Dominance Presses Against a Year-Long Resistance

Bitcoin dominance has struggled to stay above 60.5% since August 2025. Three separate attempts to reclaim that level failed.

Now, the technical picture is changing.

The weekly Supertrend indicator has turned bullish for the first time since February 2025. Bitcoin dominance has also broken out of a months-long triangle pattern.

A weekly close above 61% would strengthen the bullish signal, potentially pushing dominance toward 62%.

However, there is a catch. The daily chart shows dominance reaching the top of its rising channel, where previous rallies have struggled.

A rejection here could pull dominance back toward 60%, giving altcoins temporary relief.

Is Altcoin Season Getting Further Away?

The numbers suggest altcoin investors are already struggling.

According to CoinMarketCap, its Altcoin Season Index stands at just 39. That means roughly one-third of the top 50 cryptocurrencies have outperformed Bitcoin over 90 days.

For an official altcoin season reading, that figure must reach 75%.

The shorter-term picture is worse. The 30-day index has fallen to 24, firmly in Bitcoin season territory.

Meanwhile, recent altcoin buyers are selling at losses.

Trader cyrilXBT highlighted the problem on Wednesday: Bitcoin fell 2%, yet its dominance increased.

That means altcoins suffered even heavier losses.

For traders, the next move is crucial. A sustained breakout above 61% could extend altcoin weakness. A rejection followed by a drop below 60% would improve their chances of recovery.

Until then, the market continues to favor Bitcoin, even when Bitcoin itself is struggling.
