Zhitong App learned that according to the cryptocurrency asset management company CoinShares, the demand for Bitcoin exchange-traded funds (ETFs) accelerated again last week, with a record $2.4 billion flowing into digital asset investment products, of which Bitcoin ETFs received $2.4 billion, accounting for 99% of all inflows. In addition, the newly approved US Bitcoin spot ETF's allocation volume overshadowed the $623 million outflow from the Grayscale Bitcoin Trust (GBTC), which is an existing fund converting to an ETF structure. BlackRock's IBIT and Fidelity's FBTC attracted $1.6 billion and $648 million respectively in the past week. The outflow from Grayscale's GBTC was compensated by the significant allocations to BlackRock's IBIT and Fidelity's FBTC. James Butterfill, head of research at CoinShares, stated, "This represents a significant acceleration in net inflows, distributed among different providers, indicating a growing interest in spot-based ETFs in the market." It is worth noting that the surge in demand for Bitcoin ETFs occurred as Bitcoin reached $52,000 for the first time since December 2021, with investors expecting the largest cryptocurrency to hit new all-time highs later this year. According to the CoinShares report, inflows into the entire cryptocurrency asset category also hit a record high last week. The report stated that Bitcoin accounted for 99% of the total net inflows into cryptocurrency funds, with Ethereum products ranking second in inflows at $21 million. Meanwhile, CoinShares noted that blockchain stock ETFs suffered outflows of $167 million, indicating that investors were taking profits.
