ETF inflows surge
U.S. spot Bitcoin exchange-traded funds logged roughly $1 billion in net inflows for the week, a figure Bloomberg ETF analyst Eric Balchunas described as the funds’ strongest performance since April and the third-best week since last October.

Criptotendencias likewise said the spot Bitcoin ETF funds “registraron cerca de 1.000 millones de dólares en entradas netas,” framing the move as a sign that institutional demand regained momentum after several weeks of irregular flows.
The Block reported that U.S. spot bitcoin ETFs drew about $853.5 million in a five-session inflow streak as of Friday, while spot ether ETFs took in about $244.9 million, combining for $1.1 billion in inflows last week.
Crypto news described the same five-session run as $853.5 million in combined net inflows from Aug. 3 through Aug. 7, with daily inflows of $170.1 million, $211.5 million, $244.4 million, $128.8 million, and $98.85 million.
Balchunas tied the rebound narrative to the Coldcard wallet exploit, noting several funds have drawn inflows daily since the hack, even as The Block said that did not explain ether ETF inflows because the exploit affected only certain Bitcoin cold storage wallets.
Silent IPO debate
Balchunas characterized the earlier October period as Bitcoin’s “silent IPO,” a framing that KuCoin and Finanzen.net both tied to the idea that ETF demand can build without obvious retail-style fanfare.
Finanzen.net said the term was popularized by investor Jordi Visser in November to describe a “changing of the guard” in which early Bitcoin holders were selling into growing ETF and institutional demand.
CryptoPotato put the week’s performance in a longer arc, saying after a shaky July the Bitcoin funds started August with a bang, attracting more than $800 million in the first full week of the month.
The Block added that the combined $1.1 billion inflow week was the strongest for either category since April, and it reported that BlackRock’s IBIT accounted for $693.7 million of the total BTC fund inflows, or more than 80%.
CryptoRank reported that the $1 billion weekly figure was spread across funds including BlackRock’s IBIT and Fidelity’s FBTC, citing Balchunas’s Bloomberg Intelligence analysis.
Security and next test
Alongside the ETF inflow surge, the sources linked the week’s backdrop to a security incident involving Coldcard, described as a Bitcoin hardware wallet from Coinkite that resulted in roughly $116 million worth of Bitcoin being stolen.

Finanzen.net said the exploit was linked to a flaw in how affected devices generated wallet keys, allowing attackers to compromise funds held in wallets created using vulnerable firmware.
KuCoin reported that Balchunas suggested the hack could support the case for spot ETFs among investors wary of technical custody responsibilities, while stressing the link is speculative and that correlation does not prove causation.
The Block reported that the Coldcard exploit surfaced July 30 and said it had led to at least $111 million in thefts, with estimated total losses could exceed $130 million, citing Galaxy Research.
Across the sources, the immediate stakes were whether inflow momentum persists, with KuCoin framing the practical question as whether the improvement marks a continuation or a rebound followed by another slowdown.
