US spot Bitcoin ETFs pulled in somewhere between $865 million and $1 billion in a single week, their strongest showing since April. The catalyst? A security breach that reminded the crypto world why “be your own bank” comes with its own set of risks.
The inflows represent the third-strongest weekly performance since the notable market disruption in October 2024, and they arrived during a week when a major hack of Coldcard hardware wallets drained approximately 1,816 BTC, valued between $116 million and $130 million, across more than 5,200 addresses.
Who captured the money
BlackRock’s iShares Bitcoin Trust (IBIT) dominated the week, pulling in roughly $693 million of the total. Fidelity’s Wise Origin Bitcoin Fund (FBTC) came in second with approximately $116 million.
Before this week’s surge, US Bitcoin ETFs already held approximately $77.8 billion in assets under management.
