Bitcoin (BTC)

bitcoinethereumnews.com reports that spot Bitcoin ETFs recorded $242.30 million in net inflows on August 27, extending their consecutive inflow streak to nine trading days. Spot Ethereum ETFs matched this momentum, adding $235 million for their own ninth straight session of positive flows. This parallel performance follows heavy institutional buying, with BlackRock’s iShares Bitcoin Trust contributing $209 million to a $338 million total on August 24.
Its Ethereum fund, ETHA, added $90.92 million to that day’s $116 million haul. Bitcoin traded near $80,000 on Thursday, up 2.12% over 24 hours, while Ether moved near $2,480. Total net assets for spot Bitcoin ETFs reached $79.16 billion, with trading volume hitting $8.23 billion.
The combined weekly inflows for both categories totaled $2.3 billion, the largest since October. Smaller funds also joined the advance, with Spot Solana ETFs adding $60.91 million and Spot Hyperliquid ETFs drawing $24.42 million. The streak began on August 17 and has continued uninterrupted through August 27. Sustained demand reduces available supply on spot exchanges, a dynamic that historically supports price during accumulation phases.
How the market reacted
Whalio's own Binance spot order flow for BTC, measured when this story was written up on 28 August 2026. Not the outlet's figures.
Whalio data shows Bitcoin trading at $80,249.58 with a 1-hour buy ratio of 48.0% and a 4-hour ratio of 50.8%, contrasting with a lower 24-hour buy ratio of 45.2%. The 1-hour volume delta is negative at -$1,011,738, while the 4-hour delta is positive at +$4,782,159, indicating that short-term selling pressure is currently outweighing buying pressure despite the positive 4-hour trend. Over the full day, the volume delta sits at -$123,102,218, and the cumulative volume delta (CVD) closed at -$73,559,041. This means that over the last 24 hours, more money flowed out of buys than into buys, suggesting fading immediate buying momentum. The market saw 7 hours of net buying out of 24, with total spot volume reaching $1,297,370,375 across nearly 5 million trades.
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.
Twenty-four hours later
What BTC did over the 24 hours after the story broke. The market moves for its own reasons; this is what happened, not what the story caused.
Was that an ordinary day?
The same Binance spot measurements for BTC, averaged over the days leading up to the story.
Compared to the preceding week, the current day shows a buy ratio 5.8 percentage points below the 7-day average of 51.1%. Trading volume is also subdued, sitting at just 0.65 times the weekly average. While the coin has gained 9.9% over the past eight days, today’s volume is significantly lower than the weekly norm. The 8-day volume delta was positive at +$171,556,665, but today’s negative delta suggests a pause in that accumulation. This represents an unusual day for the coin, characterized by lower-than-average volume and a buy ratio dipping below its recent weekly trend.
