Crypto market indicators point to the altcoin season, with bitcoin share falling below 60%

Bitcoin pushes to near US$86,000, and crypto market sentiment warms up

This week, Bitcoin prices pushed to about US$86,000, driving broader crypto market sentiment and helping the total market value regain the US$3 trillion mark. At the same time, multiple cross-asset indicators have shifted-the most notable of which is one from Glassnode, which currently points to stronger performance for Altcoins. At the same time, inflows into U.S. spot ETFs have surged to their highest level since October 2025, with both Bitcoin and Ethereum-related products recording record daily net inflows. These data suggest that the current rally is not limited to the largest asset classes, but market structure remains critical as investors weigh whether this is a sustained sector rotation or a brief explosion.

Key Points

• Glassnode's altcoin cycle signal rose to 81.25 (0-100 scale), and the "altcoin season" reading improved with the latest round of market gains.
• On Tuesday, the market value of altcoins reached US$1.19 trillion, the highest level since late January; since August 19, the altcoins have risen 33% overall.
• Bitcoin's dominance has remained in the 59%-60% range, failing to break through 60% in the past month.
• According to data from Farside Investors, the U.S. spot Bitcoin ETF recorded a net inflow of $999 million on Monday, and the Ethereum ETF attracted $270 million-both are the highest total daily net inflows since October 2025.

Glassnode's "Altcoin Season" signal turns bull

Glassnode的链上分析工具本周重新引发了对市场关注，聚焦于山寨币的相对强度。其山寨币周期信号——一项内部开发的衡量标准，通过比较前250大加密货币（稳定币除外）的总市值与比特币的比例——已转为有利于山寨币，这一状况被加密交易者普遍称为“山寨币季节”（Altseason）。

在Glassnode的框架中，当顶级山寨币群体的相对市值增长暂时超过比特币时，就会生成“山寨币季节”信号。虽然基本逻辑清晰，但Glassnode并未公布计算背后的确切方法。截至周一，该信号的七日滚动平均值在Glassnode标准化的0-100刻度上为81.25，表明相比周期早期，山寨币跑赢大盘的趋势更强。

Glassnode将部分转变归因于本轮上涨的广度。该公司在X平台（原推特）的一篇帖子中指出，此前8月份的运动中，山寨币参与度滞后，而当前的上涨已经“点燃了山寨币市场的全面广度”。

山寨币市值触及1月下旬以来高点

该信号得到了市值数据的强化。数据显示，周二山寨币总市值达到1.19万亿美元，这是自1月下旬以来的最高读数。该指标自8月19日以来也显示出有意义的加速，当时由于美国财政部宣布对债券市场进行干预，加密市场出现短暂的上行波动。此后，山寨币总市值增加了33%。

For traders and fund managers, this combination-the "altcoin season" reading and rising altcoin market value-may be significant because it suggests that the rally is spreading beyond Bitcoin's leadership. However, until these rotating signals show persistence over multiple trading days and market conditions, they tend to remain fragile.

Bitcoin's dominance remains near 60%

Although the altcoin has regained momentum, Bitcoin's share of the overall market has not shown a decisive upward breakthrough. The article pointed out that since August 19, Bitcoin's dominance has been in a range of fluctuations, currently at 59.7%, compared with 59.2% on August 19.

The key is that dominance has not exceeded the 60% level in the past month-which many market observers regard as a psychological and technical threshold for determining whether funds are being withdrawn from Bitcoin or integrated within it.

Trader and commentator Matthew Hyland described the current environment as "complacency" among Bitcoin investors, who he believes have been reluctant to accept the fact that Bitcoin lacks sustained progress relative to altcoins since its dominance reached about 66% in June 2025. His comments pointed to a tension: Even if Bitcoin remains strong in absolute terms, its weak performance relative to altcoins could still lead to a strategic repositioning.

Bitcoin and Ethereum ETF inflows rebound sharply

In addition to on-chain data and market capitalization indicators, investor behavior also seems to be changing. Demand for spot bitcoin and Ethereum products in the United States rebounded broadly this week, signaling a return to risk appetite-or at least a renewed willingness to deploy through regulated channels.

On Monday, total net inflows into U.S. spot Bitcoin ETFs reached US$999 million. At the same time, the Ethereum ETF recorded a net inflow of $270 million. Based on data from Farside Investors, the total daily net inflows of both hit new highs since October 2025.

Cointelegraph previously reported that at the end of last week, the comprehensive cost benchmark for Bitcoin ETF investors was just below $86,000. As BTC/USD attempts to establish this level as support, new ETF purchases become particularly relevant: cost benchmarks can affect investors 'response to a correction, and stable inflows can help maintain demand during periods of volatility.

For market participants, the ETF perspective is also noteworthy because it connects current trends to a broader group of investors, who may prefer to invest through ETFs rather than spot exchanges. When ETF inflows rise in tandem with the improvement in the relative signal of altcoins, it may indicate a more synchronized shift in sentiment across the market.

展望未来，投资者可能会关注山寨币“季节”信号是否能保持在近期阈值之上，以及比特币主导性是能突破60%以上还是继续受限——这两种情景都将影响此次轮动的持续时间。在ETF方面，关键问题在于资金流入是否能在单日之后继续保持强劲，因为持续的需求更有可能转化为更广泛市场的持久价格领导力。
