Spot Bitcoin exchange-traded funds have recorded net inflows for six consecutive weeks, marking the longest sustained accumulation period since the initial post-launch surge in early 2024. This institutional demand keeps Bitcoin at $80,671, showing a 0.6 percent gain over 24 hours. BlackRock's IBIT and Fidelity's FBTC are absorbing substantial BTC supply, influencing market dynamics.

On-chain data confirms a drain of Bitcoin from liquid exchange reserves over the last six weeks. Exchange balances have decreased by approximately seven percent, now holding around 1.9 million BTC. This supply compression indicates a structural shift, moving Bitcoin from actively traded venues into long-term, custodied ETF holdings. This sustained off-exchange movement reduces immediate sell pressure.

The persistent demand from these regulated investment vehicles highlights growing institutional conviction in Bitcoin as a core portfolio asset. These capital flows are distinct from speculative retail trading, often representing broader asset allocations from pension funds and endowments. While Bitcoin leads this charge, other major digital assets like Ethereum, trading at $2,326, have also seen positive but less consistent upward momentum during this period. The Crypto Fear & Greed Index sits at 47, signaling neutral market sentiment despite the consistent buying pressure.

This six-week streak directly impacts miner economics and overall market structure. With ETF buying absorbing new supply and even some existing coins, miners face a more favorable environment post-halving. They are not forced to liquidate holdings to cover operational costs, unlike periods earlier this year when collective miner sales exceeded 8,000 BTC in a single week. This strengthens the market's ability to absorb sell-side pressure.

The continuous demand from ETFs solidifies Bitcoin's position as a macroeconomic asset. It demonstrates that the market views Bitcoin less as a volatile speculative play and more as a legitimate store of value. This shift is critical for investors holding long positions, as sustained institutional backing suggests a more resilient price floor moving forward.
