Altcoin Cycle Signal Flips as Bitcoin Dominance Stalls Below 60%

Market shift toward alternative cryptocurrencies

A key onchain metric has signaled a shift in the cryptocurrency market toward alternative coins, often called altcoins, rather than Bitcoin. The "Altcoin Cycle Signal" from analytics platform Glassnode recently hit a reading of 81.25 out of a maximum 100. This metric suggests that alternative cryptocurrencies are currently growing in value faster than Bitcoin. This development comes as the total market value of the crypto industry reclaimed $3 trillion. Bitcoin’s price rose to $86,000 earlier this week, which helped drive the overall market higher. Despite Bitcoin’s price increase, its share of the total crypto market has not grown significantly.

Key market numbers

• Glassnode’s Altcoin Cycle Signal reached 81.25, indicating altcoin strength.
• The combined market value of the 250 largest altcoins hit $1.19 trillion, its highest level since late January.
• Altcoin market cap has grown by 33% since August 19.
• Bitcoin’s market share, or dominance, has stayed between 59.2% and 59.7% for the past month.
• US spot Bitcoin exchange-traded funds (ETFs) saw $999 million in inflows on Monday.
• Ether (ETH) ETFs received $270 million on the same day.

What the data shows

The Altcoin Cycle Signal compares the market value growth of the 250 largest cryptocurrencies against Bitcoin. It ignores stablecoins, which are digital currencies tied to the value of traditional money like the US dollar. The signal turns positive when the combined growth of these altcoins is temporarily stronger than Bitcoin’s growth. Glassnode reported in a post on X that the current rally is different from previous ones. While the first rally in August saw Bitcoin rise while altcoins stayed flat, the current rally has benefited the entire altcoin market. Bitcoin’s market share has remained in a narrow range recently. It stood at 59.7% on Monday, compared to 59.2% on August 19. This period of flat dominance has lasted since Bitcoin reached a market share high of 66% in June 2025.

Investor perspectives and ETF flows

Trader and commentator Matthew Hyland described the current situation as a state of "complacency" among Bitcoin investors. He argued that investors have been unwilling to accept that Bitcoin has not gained ground against other cryptocurrencies since its dominance peaked earlier in the year. Meanwhile, investor demand for crypto funds has rebounded. According to data from UK-based investment firm Farside Investors, Monday’s inflows were the highest for both Bitcoin and Ether ETFs since October 2025. An exchange-traded fund, or ETF, is an investment product that tracks the price of an asset and trades on traditional stock exchanges. Data also shows that the average cost basis for Bitcoin ETF investors sat just below $86,000 at the end of last week. This is the price level at which most ETF holders originally bought their positions.

What is confirmed and what is unclear

Confirmed:

• Glassnode’s Altcoin Cycle Signal is at 81.25.
• Altcoin market cap reached $1.19 trillion on Tuesday.
• Bitcoin ETFs saw $999 million in inflows on Monday.
• Bitcoin’s dominance is around 59.7%.

Unclear:

• Glassnode does not disclose the exact methodology behind its calculation.
• It is not confirmed if the altcoin outperformance trend will continue or if Bitcoin dominance will rise again.

Why this matters

The shift in the Altcoin Cycle Signal and the stabilization of Bitcoin’s market share suggest a broader participation in the crypto market beyond just Bitcoin. For investors, this indicates that value is spreading across different types of cryptocurrencies. The high inflows into ETFs show that traditional investors are actively moving money into these assets.

Next steps

The article does not provide a specific timeline for future market movements. Investors are now watching whether Bitcoin’s dominance will break above 60% again or if altcoins will continue their current growth trajectory.
