Bitcoin ETF Inflows Break 12-Day Streak as Investors Rotate into Altcoins

U.S.-listed spot Bitcoin ETFs recorded $131.4 million in outflows on Monday, snapping a 12-day streak of consistent inflows that had pulled in more than $6 billion. The pause comes as Bitcoin price action slows and investors begin shifting capital toward altcoins, particularly Ethereum.

Bitcoin (BTC) traded mostly flat to start the week, hovering just below $118,000 after hitting a record high near $124,000 two weeks ago. The ETF inflow streak had closely paralleled Bitcoin’s surge, signaling strong institutional participation throughout the rally.

While Monday’s outflows do not necessarily suggest a reversal in sentiment, they highlight a temporary cooling in demand for Bitcoin exposure through ETFs — ending one of the most sustained inflow periods since their inception.

At the same time, capital is flowing more aggressively into altcoin-linked products. Ether ETFs attracted $296.5 million in inflows on Monday alone, bringing cumulative inflows to $8 billion since July 2. The ETH/BTC ratio — a widely watched gauge of relative performance — has rebounded sharply, rising 24% over the past week and 39% over the past month.

The contrast in ETF flows may signal a broader investor rotation, with market participants rebalancing portfolios or seeking new opportunities following Bitcoin’s recent dominance. The renewed interest in Ethereum could also reflect growing confidence in altcoin market recovery.

Despite the slowdown in ETF inflows, Bitcoin remains up nearly 20% over the past month and continues to trade near all-time highs. Market volatility persists, but capital allocation within crypto appears alive and dynamic, as investors shift focus across the digital asset landscape.
