US-listed spot Bitcoin exchange-traded funds (ETFs) attracted strong investor interest this week, recording net inflows of $382 million over two consecutive trading sessions as concerns over cryptocurrency security intensified following the recent Coldcard wallet hack.
According to SoSoValue, spot Bitcoin ETFs recorded $170 million in net inflows on Monday, followed by an additional $211.5 million on Tuesday, signaling renewed confidence in regulated Bitcoin investment products despite ongoing market uncertainty.
The inflows came as the crypto community continued to assess the impact of the Coldcard security incident. Galaxy Research estimated that the breach may have affected nearly 7,300 Bitcoin addresses, with suspected losses totaling around $130 million worth of Bitcoin. The incident has reignited discussions over the safety of self-custody compared with institutional custody offered through regulated financial products.
Among the biggest beneficiaries of the renewed investor demand was BlackRock’s iShares Bitcoin Trust (IBIT), which led all spot Bitcoin ETFs with approximately $111 million in inflows on Monday and $170 million on Tuesday. Fidelity’s Wise Origin Bitcoin Fund (FBTC) also attracted fresh capital, recording around $33 million and $20 million in inflows over the two sessions.
Meanwhile, the Invesco Galaxy Bitcoin ETF (BTCO) posted $6.7 million in inflows on Monday, marking its first positive daily flow since July 1. The latest investment represented nearly 3.9% of the fund’s cumulative net inflows of $172 million, according to Farside Investors.
The Coldcard incident has renewed the long-running debate over Bitcoin custody. Bloomberg Intelligence Senior ETF Analyst Eric Balchunas said the hack could encourage more investors to choose Bitcoin ETFs, where digital assets are held by regulated institutional custodians rather than through self-managed wallets.
Despite the security concerns, Bitcoin (BTC) remained relatively stable in the market. At the time of publication, the cryptocurrency was trading at around $64,113, down approximately 0.8% over the past seven days after briefly falling below $62,500 during the week.
Market analysts also noted that stolen Bitcoin may be difficult for hackers to move or liquidate because blockchain transactions are publicly traceable, allowing exchanges and blockchain investigators to monitor suspicious transfers.
