Bitcoin Records $14,775 Weekly Surge Driven by ETF Flows
Bitcoin (BTC)

According to cryptocurrency.com.tr, Bitcoin achieved its largest one-week dollar increase in history by gaining $14,775. The asset’s price closed the week at $77,593, up from $62,818, representing a 23.5% move. This percentage gain marks Bitcoin’s best weekly performance since March 2023, though it ranks as the 41st largest percentage increase since 2010.
Galaxy Research attributed this rally to the strongest US spot Bitcoin ETF inflow week since October 2025. The research firm linked the price action to two specific catalysts. First, the US Treasury announced it would double its long-bond buyback operations to ease pressure on Treasury yields.
Second, President Trump urged Congress to pass the CLARITY Act. This legislation aims to establish federal rules for classifying digital assets as either securities or commodities. These combined factors drove the single largest weekly gain by dollar amount in Bitcoin's history.
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 24-hour spot volume of $1,297,370,375. Short-term buying pressure appears to be building, as the 1-hour buy ratio stands at 52.2% and the 4-hour ratio is at 50.8%. However, this contrasts with the 24-hour buy ratio of 45.2%, indicating that net buying has weakened over the full day. The 1-hour volume delta is positive at +$1,283,983, while the 4-hour delta is +$4,782,159, but the 24-hour delta is negative at -$123,102,218. This divergence suggests that recent trades are more bullish than the daily average, despite a net outflow over the last 24 hours. The Cumulative Volume Delta for the 24-hour close is -$69,334,167, confirming that sellers dominated the total volume during this period.
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.
Over the preceding week, the average buy ratio was 51.1%, but the latest day saw this drop by 5.8 points. Volume during this period was only 0.65 times the average, indicating significantly reduced trading activity compared to normal days. The coin experienced a price change of +9.9% over eight days, with a total volume delta of +$171,556,665. While the weekly trend was positive, the current 24-hour volume of $1,297,370,375 is a single-day snapshot that does not directly match the weekly aggregate of $171,556,665. The recent 24-hour net selling of -$123,102,218 contrasts with the weekly net buying, suggesting a shift in momentum after a period of accumulation.
