Bitcoin (BTC)

news.bitcoin.com reports that U.S. Bitcoin ETFs posted a fourth consecutive day of outflows on Friday, losing $13.29 million. Ether funds moved in the opposite direction, attracting $216.41 million in net inflows and closing a fourth consecutive week with positive flows. Blackrock’s IBIT recorded a $19.23 million outflow, which outweighed fresh demand from Morgan Stanley’s MSBT, which added $3.76 million, and Vaneck’s HODL, which added $2.18 million.
Total Bitcoin ETF trading value reached $2.60 billion, with net assets closing at $97.58 billion after a cumulative week of $462.73 million in outflows. Ether ETFs saw their strongest move with Blackrock’s ETHA leading with $148.82 million, while Bitwise’s ETHW added $29.09 million. BlackRock’s ETHB attracted $18.32 million, Fidelity’s FETH brought in $11.40 million, and Grayscale’s Ether Mini Trust and Vaneck’s ETHV added $5.09 million and $3.71 million respectively.
The surge pushed Ether ETFs to roughly $197 million in weekly net inflows, extending their winning streak to four weeks. HYPE ETFs lost $8.18 million, Solana ETFs slipped by $278,840, and XRP ETFs recorded no net flows. August CPI rose 0.4% from July, with annual inflation holding at 3.4% and core inflation easing to 2.4%. With no clear dovish catalyst, the path back above $80,000 may depend on softer economic data or a more supportive signal from the Federal Reserve.

Whalio’s Binance spot data shows Bitcoin trading at $77,225.70 with a 1-hour buy ratio of 34.3%, indicating short-term selling pressure.

The 1-hour volume delta is -$6,651,833, reflecting immediate outflows, while the 4-hour delta is positive at +$17,245,011. Over 24 hours, the buy ratio sits at 50.0% with a negative volume delta of -$503,152, showing a balanced but slightly bearish daily flow. CVD for the 24-hour close is +$45,433,939, indicating that cumulative buying pressure has outweighed selling over the full day. Spot volume reached $1,528,809,492 with 3,614,263 trades, and there were 13 hours of net buying out of 24.
The latest daily buy ratio of 46.7% sits at the 18th percentile of the last 322 days, against a median of 49.2% - weaker buying than most days.
Was that an ordinary day?
The same Binance spot measurements for BTC, averaged over the days leading up to the story.
Over the preceding week, the average buy ratio was 46.4%, making today’s 24-hour ratio of 50.0% an increase of 3.6 percentage points. Trading volume was 1.40x the weekly average, indicating heightened activity compared to normal days. However, there were 0 days of net buying over the past 7 days, contrasting with the current day's mixed signals. The price change over 8 days is -3.1%, with a total volume delta of -$580,119,242 for the period. This suggests that while today shows signs of renewed buying interest, the broader weekly trend remains dominated by outflows.
