Bitcoin (BTC)

lookonchain.com reports that BTC OG Insider Whale Garrett Jin views Bitcoin as approaching a dense supply zone between $80,000 and $82,500. This area contains on-chain cost levels formed during the final rally before the recent sell-off. Despite this overhead supply, capital flow data remains strong, with U.S. spot ETFs attracting ~$2.8 billion over eight consecutive days ending August 26.
August’s inflows reached roughly $3.3 billion, marking the highest monthly total of the year. On-chain metrics show a positive 7-day moving average of net realized profit and loss at ~$752 million. Jin argues that a consistent close above $82,500 would signal full absorption of circulating supply.
Conversely, a single-day close below $76,600 is manageable, but deterioration in three specific metrics would serve as a warning. Garrett Jin’s address added 600 BTC long positions at $79,000 on the early morning of August 26. He now holds 1,868 BTC long positions with an average entry price of $77,090.
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.
Bitcoin is trading at $80,249.58, with the 1-hour buy ratio at 52.3% contrasting sharply against a 4-hour ratio of 39.8%. The 24-hour buy ratio sits at 45.2%, indicating that buying pressure is fading over the longer timeframe. Volume delta shows +$1,968,400 in the last hour, but drops to -$36,806,801 over 4 hours and -$123,102,218 over 24 hours. This negative volume delta means that sell volume has exceeded buy volume over the medium and long terms. The cumulative volume delta for the 24-hour close is -$107,359,372, confirming that sellers are currently in control of the flow. Net buying occurred for only 8 of the 24 hours, suggesting inconsistent demand.
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%, making today’s 24-hour ratio of 45.2% lower by 5.8 points. Spot volume for the 24-hour period is $1,297,370,375, which is 0.65x the weekly average, indicating significantly lower activity than usual. While the price rose 9.9% over eight days, the current day shows a deviation from the recent average buying behavior. This represents an unusual day for the coin, characterized by lower volume and reduced buy ratios compared to the weekly norm. The total volume delta for the eight-day period was +$171,556,665, highlighting a strong weekly trend that is currently cooling off.
