Cryptobriefing.com reports that Bitcoin retreated below $78,000 after briefly climbing past $79,500 on September 14. The rally faded as prediction market odds for the Digital Asset Market Clarity Act collapsed from 30% back to 18%. This legislation aims to define jurisdictional lines between the CFTC and SEC over digital assets.
Senate Republicans released a revised draft incorporating 126 changes requested by Democrats. This accommodation briefly inflated the bill's passing probability on Polymarket. However, sentiment reversed as the reality of a divided Senate reasserted itself.
The bill faces a cloture vote on September 15 requiring 60 votes to advance. Republicans hold 53 seats and need at least seven Democrats to cross the aisle. Resistance is building from state attorneys general and financial institutions. Bitcoin still commands roughly 60% of total crypto market capitalization.
How the market reacted
Whalio's own Binance spot order flow for OP, measured when this story was written up on 15 September 2026. Not the outlet's figures.
Optimism is currently strong for OP, with the 1-hour buy ratio at 65.0% and the 4-hour ratio at 61.6%. These figures are notably higher than the 24-hour buy ratio of 59.6%, indicating that buying pressure is building in the short term. The volume delta shows +$78,878 over the last hour and +$355,237 over four hours. This positive volume delta means buyers are actively absorbing sell orders, pushing the price up. Cumulative Volume Delta for the 24-hour close is +$1,734,637. Net buying occurred for 17 of the last 24 hours.
The latest daily buy ratio of 46.4% sits at the 5th percentile of the last 324 days, against a median of 50.1% - among the weakest buying days it has had.
Was that an ordinary day?
The same Binance spot measurements for OP, averaged over the days leading up to the story.
Over the preceding week, the average buy ratio was 49.8%, making today's 24-hour ratio of 59.6% an unusual spike of 9.8 points. Trading volume was 1.57 times the average, signaling heightened activity. Despite this increased buying interest, the price dropped 7.2% over the eight-day period. The total volume delta for the week was +$834,078. This suggests that while buying intensity has surged recently, the broader trend has been bearish.
