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 latest investment represented nearly 3.9% of the fund’s cumulative net inflows of $172 million, according to Farside Investors.
