U.S. spot Bitcoin (BTC) and Ether (ETH) exchange-traded funds pulled in a combined $1.1 billion last week, their strongest showing since April, even as trading volume stayed near multi-year lows.
Key Points:
- U.S. spot Bitcoin ETFs drew about $853.5 million across five straight sessions through Friday, their best week since mid-April.
- Spot Ether ETFs added $244.9 million, extending a positive run to five consecutive weeks, the longest of 2026.
- Trading volume moved the other way, with Bitcoin ETF turnover falling 9 percent to roughly $8.19 billion.
Bitcoin ETF Inflows Lead The Week
Spot Bitcoin funds <a href="https://www.theblock.co/news/markets/2026-08-08-bitcoin-ether-etfs-draw-1-1-billion-in-best-inflow-week-since-april-despite-low-volume-411204">took</a> in about $853.5 million across five straight sessions through Friday, according to SoSoValue data compiled over the trading week. That was their largest weekly total since the week ending Apr. 17, when the category drew $996.4 million from investors. Spot Ether funds added $244.9 million, likewise their best result since that same week in the spring.
BlackRock's IBIT accounted for $693.7 million of the Bitcoin haul, more than 80 percent of the total, while Fidelity's FBTC contributed $116.4 million, or about 13 percent.
Daily flows peaked Wednesday at $244.4 million, followed by $211.5 million on Tuesday. Buying then faded into the weekend, with Thursday and Friday bringing $128.7 million and $98.9 million as U.S. payrolls fell by 23,000 against forecasts for a gain of 80,000 jobs.

Balchunas Links Flows To Coldcard Exploit
Eric Balchunas, senior ETF analyst at Bloomberg Intelligence, <a href="https://cointelegraph.com/news/us-bitcoin-etfs-best-weekly-inflows-april-coldcard-hack">wrote</a> Friday on X that IBIT, FBTC and several other funds have drawn money every single day since the Coldcard exploit surfaced on July 30.
He said it was hard not to see causation in the correlation, and called the timing ironic but somehow on brand for this market. Galaxy Research <a href="https://www.cryptotimes.io/2026/08/08/galaxy-research-confirms-111m-stolen-funds-in-coldcard-exploit/">confirmed</a> Friday that 1,719 Bitcoin worth roughly $111 million had been stolen from users, and warned that total losses will likely exceed $130 million. Researchers <a href="https://www.trmlabs.com/resources/blog/the-largest-hardware-wallet-exploit-of-2026-inside-the-usd-116-million-coldcard-hack">traced</a> the flaw to a March 2021 firmware update that generated recovery seeds with far less randomness than the devices had promised buyers.
Ether ETF Streak Meets Thin Volume
Ether funds have now strung together five positive weeks, their longest run of 2026, with Thursday's $92.2 million marking the largest single day of the stretch.
That complicates the Coldcard reading, because the vulnerability touched only certain Bitcoin hardware wallets, and the Ether inflow run began on Aug. 3, several days after the bug was first disclosed.
The rebound has limits. Bitcoin ETF turnover reached roughly $8.19 billion, down 9 percent on the week and the second-lowest full trading week since October 2024, while Ether volume slid about 21 percent. Both categories also remain deep in the hole for the year, with Bitcoin funds sitting on about $4.44 billion in net outflows since January and Ether funds down roughly $873 million over the same stretch.
