Bitcoin Signals Fresh Bull-Market Shift as ETF Inflows Surge and Prices Jump

Bitcoin is showing signs of a new bull-market regime after climbing about 24% from the mid-$60,000s to roughly $80,000–$81,000. Spot demand, ETF buying and price momentum have turned firmly constructive. At the same time, heavier profit-taking, rising exchange inflows and increasingly overbought signals point to the risk of a near-term pause. Key data Price action: BTC has risen about 24% since Aug. 17, pushing above $80,000 — the highest level since mid-May — before settling into a consolidation range around the high-$78,000s to low-$80,000s. It was the strongest weekly gain in more than three years. Regime shift: The Bull Score surged from 30 to 80 in a single week, with 8 of 10 indicators now flashing bullish. Spot demand is expanding at its fastest monthly pace since late December. Spot and futures demand are rising together for the first time since early October 2025. ETF flows: U.S. spot Bitcoin ETFs logged around $1.92B of net inflows from Aug. 17–21, the strongest week in 10 months. Inflows extended with another $337.6M on Aug. 24, marking six straight inflow days. August month-to-date inflows are now near $2.7B. Derivatives: Funding rates remain mildly positive at roughly 0.01%, with no clear signs of excessive leverage. Coin-denominated open interest cooled as traders deleveraged into the rally, while dollar-denominated open interest increased alongside price. Earlier in the week, large short liquidations helped accelerate the squeeze. On-chain caution: Traders' unrealized profit margins jumped to 20.5%, the highest since June 2025. Whales realized a record roughly $614M in profits on Aug. 20. Rising exchange inflows of BTC, ETH and XRP also suggest increasing near-term distribution pressure. The Fear & Greed Index remains in "Greed" at about 73. Takeaway: The setup increasingly resembles a genuine shift into the early stage of a new bull market, driven more by strengthening spot demand and institutional ETF buying than by leverage. Markets will be watching for a sustained close above the roughly $83,000 365-day moving average.
