Bitcoin Dominance falls: A breakthrough opportunity for altcoin or a warning sign for the market?

Bitcoin Dominance (BTC.D) has fallen sharply from over 61% to 58.8% in November 2025, amid the Altcoin Season Index rising to its highest level in more than a month.

Although the rise of this index cannot confirm that the altcoin season has begun, many analysts believe that the downtrend of BTC.D may continue, creating momentum for altcoins to develop more strongly.

The fall of BTC.D: Market shift signal?

BTC.D is an index that reflects the market capitalization share of Bitcoin compared to the entire cryptocurrency market, playing a key role in identifying the flow of capital between Bitcoin and altcoins.

According to the latest data, BTC.D has significantly fallen in November 2025, from 61.4% to 58.8%. Meanwhile, the Altcoin Season Index has continuously risen since last week, currently reaching 47 points – the highest level since mid-October.

However, this is not yet a sign of a strong price rise for altcoin, but rather indicates that Bitcoin is losing value faster than altcoin, even though both groups are on a downward trend.

This trend has sparked much debate about whether it is just a temporary adjustment or signals a deeper capital rotation cycle. Analyst ChartingGuy noted on the weekly chart that BTC.D is shifting to a clear downward trend.

“The BTC.D index is the driving force behind my expectations. Finally, it has also reversed to fall on the weekly chart.”

According to ChartingGuy's analysis, the decline of BTC.D could lead to two scenarios: either Bitcoin will fall deeper than altcoins, or the market will recover with the outperformance of the altcoin group. He believes that the first scenario is more likely to occur, based on the head-and-shoulders pattern forming on the technical chart.

Meanwhile, expert Gert van Lagen emphasized the long-term significance of this structural break. He pointed out that BTC.D has broken the rising trend lasting over three years, retested this area, and is currently continuing to fall in smaller time frames.

“When Bitcoin recovers, altcoins will have the opportunity to rise significantly.”

Typically, the decline of BTC.D is a signal that capital is shifting towards riskier assets, setting the stage for altcoin to rise significantly. However, if Bitcoin continues to fall faster than altcoin, this may reflect the overall weakness of the entire market rather than a real price increase of altcoin.

Therefore, this decline is seen as an important turning point, which could both open up recovery opportunities for altcoins and signal deeper downward pressure on the market. Nevertheless, many analysts believe that this is a time to seize opportunities rather than to worry excessively.

“Technically, BTC.D is showing strong potential to fall, and that is an extremely positive signal for altcoins. Deep drops of 80% in altcoins? In my opinion, that's an opportunity, not a reason to panic. This is a significant moment, and very few people realize what is coming,” an expert commented.

As BTC.D continues to weaken, the coming weeks will play a decisive role in the movement trend of the entire cryptocurrency market.
