Bitcoin ETFs Continue Inflow Streak as Ether and Zcash Funds See Outflows

Markets | Published: Sep 30, 2026

US spot Bitcoin exchange-traded funds (ETFs) have extended their impressive net inflow streak to nine consecutive trading days, demonstrating sustained investor interest in the flagship cryptocurrency. This positive trend for Bitcoin contrasts with recent outflows observed in Ether and Zcash funds, signaling a potential shift in investor sentiment towards specific altcoins.

On Tuesday, Bitcoin ETFs attracted a substantial $66.2 million. This latest influx has propelled the cumulative net inflows over the current winning streak to approximately $3.1 billion, according to data compiled by SoSoValue. The year-to-date net inflows for Bitcoin ETFs have now reached roughly $1 billion, underscoring the significant capital deployment into these regulated investment vehicles since their inception.

However, the broader altcoin market has experienced a reversal in fortunes. Spot Ether ETFs, after a remarkable seven-day period of inflows, ended their streak by posting net outflows of approximately $3 million on Tuesday. While this outflow is relatively modest compared to the substantial inflows seen during the preceding week, it marks a notable pause in the upward momentum for Ether-focused funds. During their seven-day inflow streak, these Ether ETFs had accumulated over $851 million, bringing their cumulative net inflows to a considerable $14 billion.

The trend of outflows extended to other altcoins as well. Earlier in the week, Zcash ETFs experienced a similar reversal, snapping a six-day inflow streak by recording $8 million in net outflows on Monday. This indicates a broader cooling of investor enthusiasm for certain smaller-cap cryptocurrencies, at least in the short term.

At the time of publication, Bitcoin was trading at approximately $83,567, reflecting a slight decrease of 0.4% over the preceding 24 hours, according to data from CoinGecko. The broader cryptocurrency market sentiment also showed signs of softening. Alternative.me’s Crypto Fear & Greed Index, a popular barometer of market sentiment, slipped to 71 from 73 a day earlier. Despite this slight decline, the index remains firmly within the "Greed" territory, suggesting that investors are still optimistic about the market’s prospects, albeit with a slightly more cautious outlook.

Kyle Rodda, senior financial market analyst at Capital.com, commented on the current market dynamics, suggesting that the recent rise in crude oil prices might be influencing investor behavior. "The rise in crude prices is capping non-yielding assets, so Bitcoin’s rally has taken a bit of a pause," Rodda explained to Cointelegraph. This perspective suggests that macroeconomic factors, such as inflation concerns reflected in energy prices, could be temporarily impacting the performance of assets like Bitcoin, which are often perceived as inflation hedges but can also be sensitive to broader risk appetite.

Rodda further elaborated on the potential challenges facing Bitcoin’s upward momentum. He indicated that Bitcoin could struggle to regain significant upward momentum as long as energy price risks persist. However, he also offered a cautiously optimistic outlook on Bitcoin’s technical positioning, stating that its technical picture remained "quite constructive." This implies that despite short-term headwinds, the underlying technical indicators for Bitcoin suggest a potential for future price appreciation.

The recent performance of Bitcoin ETFs, characterized by sustained inflows, is a key indicator of institutional adoption and growing acceptance of cryptocurrencies as a legitimate asset class. The availability of regulated ETFs has lowered the barrier to entry for traditional investors, allowing them to gain exposure to Bitcoin through familiar investment vehicles. This institutional demand has been a significant driver of Bitcoin’s price appreciation in recent periods.

The contrasting performance of Ether and Zcash ETFs highlights the inherent volatility and sector-specific dynamics within the cryptocurrency market. While Bitcoin has demonstrated remarkable resilience and continued inflows, other digital assets may experience more pronounced fluctuations in investor interest based on evolving market narratives, technological developments, and macroeconomic influences.

The Crypto Fear & Greed Index remaining in "Greed" territory, despite a slight dip, suggests that the overall bullish sentiment among market participants is still dominant. However, the subtle shift downwards indicates a degree of caution, possibly driven by concerns about inflation or other macroeconomic uncertainties that could impact riskier assets.

The interplay between macroeconomic factors, such as crude oil prices, and the performance of digital assets like Bitcoin is a crucial aspect of understanding current market trends. As Rodda pointed out, the current environment where energy prices are rising can put pressure on assets that do not generate income, potentially leading to a temporary pause in rallies. This suggests that investors are actively weighing various economic indicators when making investment decisions.

Despite the short-term pauses and outflows in certain altcoin funds, the long-term outlook for digital assets remains a subject of intense debate and analysis. The continued strong inflows into Bitcoin ETFs are a significant testament to the growing institutional embrace of this asset class. Meanwhile, the performance of altcoin ETFs will likely be closely watched as indicators of broader market sentiment and the evolving landscape of digital asset investment.
