Bitcoin dominance signals retest breakout: Is altseason 2026 next?

Bitcoin (BTC) dominance has consolidated in a tight range of 60% and 58.8% between January 1, and March 10, 2026, thus further delaying altseason 2026.

In the weekly timeframe, the BTC dominance has, however, signaled its reversal after breaking down from a bearish pennant pattern, according to renowned crypto trader TATrader_Allan. 

The cryptocurrency analyst believes that Bitcoin dominance, in the weekly chart, has already formed a lower low, thus predicting a fresh capitulation in the coming weeks.

As such, the odds of altseason 2026 materializing in the coming months, akin to the 2021 crypto summer, have surged significantly. Moreover, the Altcoin Season Index has risen to 37/100 at press time from 22/100 at the beginning of February, based on data from CoinMarketCap.

How big will altseason 2026 be as BTC dominance reverses 

From a technical analysis standpoint, the 2026 altseason is expected to mirror its 2021 performance, as per crypto trader Matthew Hyland. He argued that an incoming monthly death cross of Bitcoin dominance will trigger its next major crash below 40%.

However, with the help of institutional funds and mainstream retail adoption, the altseason 2026 could outshine its 2021 performance to mirror the 2017 bull market. 

What’s the ultimate trigger for an altcoin bull rally in 2026? 

The ultimate trigger for an altcoin bull rally in 2026 will be the passage and enactment of the Clarity Act in the United States. Furthermore, Cardano (ADA) founder Charles Hoskinson has argued in the past that the delay of passing the Clarity Act in 2025 caused the bull market’s misfire.

With President Donald Trump advocating for the passage of the digital assets market structure bill before the end of this year, an altcoin’s bull rally is well-positioned to kickstart before the end of this year.
