Week of 3 August 2026: Bitcoin gains 2.09% on below-average volume
When both assets rise modestly on light volume, what can a quiet week say about the trend, and what can it not say about the strength behind it?
BTC rose from 63,570.01 to 64,901.59 (+2.09%) and ETH from 1,885.36 to 1,910.65 (+1.34%). Both weekly lows came at 08:00 UTC on Monday 3 August. Dollar volume was 0.63 times BTC's and 0.59 times ETH's prior twelve-week average.
What the data shows. Both assets bottomed early: BTC's low of 62,300 and ETH's low of 1,828.62 came in the same hour, 08:00 UTC on Monday 3 August. From there BTC climbed to a weekly high of 65,474.46 late on Sunday 9 August and closed at 64,901.59, near the top of its range (close location 82.0%). ETH peaked earlier, at 1,943.02 on Friday 7 August, then eased. Daily moves were small: BTC's best day added 0.93% and its worst took 0.53% back; ETH's best day added 2.09% and its worst cost 1.32%. The two tracked each other closely (hourly correlation 0.83), and the ETH/BTC ratio fell 0.74%, so ETH lagged slightly rather than diverging sharply. Trading activity was light: BTC dollar volume of 4.92 billion and ETH volume of 2.14 billion ran well below the prior twelve weeks.
What it does not show. Light volume and a steady rise do not reveal who was buying or whether the move was directional rather than thin-market drift. BTC sits 48.5% below its 52-week high and ETH 61.28% below its own, so a 2.09% week does not establish a turn. The data contains no open interest or order-book figures, so the size of positions behind the move cannot be measured.
What a careful desk would check. Realised volatility, the size of the swings that actually happened scaled to a yearly figure, was 21.5% for BTC and 28.1% for ETH — low but not extreme. A desk would ask whether the Sunday BTC high into the close holds, and whether later weeks show volume returning towards the prior twelve-week average. It would also weigh the modest weekly return (61st percentile of 442 weeks for BTC, 56th for ETH) as ordinary rather than informative.
Funding. Funding averaged 0.0049% per eight hours for BTC and 0.0035% for ETH, both slightly positive, so longs paid shorts a small carry. The data has no open-interest figures, so the size of the positions paying that carry cannot be measured here. The lowest eight-hour ETH funding reading recorded in the week was -0.0009%.
What would change this reading
- If volume stays near 0.6 times its prior twelve-week average while price drifts higher, the advance remains thin and easier to reverse.
- If BTC trades back below its Monday low of 62,300, the week reads as a pause inside a broader decline rather than a base.
- If ETH/BTC resumes falling after this week's -0.74%, ETH is losing ground to BTC, which changes which hedge matters.
- If funding rises towards 0.01% while volume stays light, longs are paying more for a move that few participants are trading.
Terms
- realised volatility
- how much the price actually swung over a period, expressed as a yearly percentage
- close location
- where the closing price sits within the week's high-low range, in percent
- perpetual funding
- a regular payment between long and short holders of a perpetual futures contract; slightly positive means longs pay shorts
