U.S. spot Bitcoin ETFs pulled in $790.6 million in net inflows over the seven-day period ending Aug. 6, according to flow data. The week saw just one losing session — July 31, when funds shed $212.7 million — followed by four straight days of gains. The inflows came as the Coldcard exploit dominated industry headlines, renewing debate over self-custody and operational security.
The one red session
July 31 was the only negative day of the stretch, with $212.7 million in net outflows. That was the last hiccup. Over the next four trading sessions, the funds went on a run: Aug. 3 added $170.1 million, Aug. 4 brought $207.8 million, Aug. 5 saw $241.6 million, and Aug. 6 chipped in another $99.4 million. All told, inflows for the week crossed $1.0 billion, while outflows stayed at that single $212.7 million blip. The recovery was quick and consistent, with the biggest single-day gain landing on Aug. 5.
IBIT did the heavy lifting
BlackRock's IBIT accounted for the bulk of the action. The fund posted $757.5 million in rolling net inflows over the seven days, stretching its own streak to four consecutive inflow sessions. On the latest trading day alone, IBIT added $128.3 million. Fidelity's FBTC brought in $11.2 million that day, and Bitwise's BITB added $1.7 million. Those three funds combined for most of the day's total, though the exact split across other issuers wasn't disclosed.
Coldcard hangs over the week
The Coldcard exploit was one of the biggest Bitcoin security stories of the year, reigniting industry arguments about self-custody and operational security. Yet the ETF flow data doesn't reveal what buyers made of it. It's impossible to say whether they saw the exploit as insignificant, a buying opportunity, or simply a side note to their longer-term strategies. What's clear is that institutional demand for Bitcoin ETFs stayed resilient during a week when security dominated the conversation. The flows don't tell us if anyone changed their mind — only that money kept moving in.
