12-Day Inflow Run for Bitcoin ETFs Breaks Amid Market Pause

Bitcoin ETF Inflows Snap 12-Day Streak as Capital Shifts to Ethereum

Spot Bitcoin ETFs saw $131.4 million in outflows on Monday, ending a 12-day streak of continuous inflows that had attracted more than $6 billion, according to Farside Investors. The pause in momentum reflects both a cooling in Bitcoin’s price action and a broader shift in investor focus toward altcoins.

Bitcoin (BTC) remained largely unchanged to start the week, trading near $117,700 after peaking just below $124,000 two weeks ago. The 12-day inflow streak had mirrored Bitcoin’s strong rally, signaling robust institutional interest. Monday’s pullback, however, marks the first sign of hesitation following one of the most aggressive ETF accumulation phases since the product’s debut.

While the outflows may not signal a full reversal in sentiment, they underscore a market in transition. Altcoins — particularly Ethereum — are attracting growing attention. Ether ETFs brought in $296.5 million on the same day, pushing total net inflows since July 2 to $8 billion. The ETH/BTC ratio, long in decline, has surged 24% over the past week and 39% over the past month.

This divergence between Bitcoin and Ether ETF flows suggests a rebalancing by investors aiming to diversify or capitalize on Ethereum’s relative strength after months of underperformance. The move may also reflect renewed confidence in altcoin fundamentals as Bitcoin’s rally plateaus.

Despite the break in ETF momentum, Bitcoin remains nearly 20% higher over the past month and continues to trade near record highs. With capital still flowing into digital assets — though now more selectively — the rotation could signal the early stages of a broader altcoin resurgence.
