According to Coinbase's weekly market report, the latest 13F filings for US spot bitcoin exchange-traded funds show signs of growing institutional interest in the digital asset. "An increasing portion of these flows appears to be institutional-driven, with institutional holdings rising from 21.4 per cent to 24.0 per cent," the report said. The report highlights the increase in institutional inflows into the category of "investment advisors", who manage large amounts of money and typically make decisions on asset allocation, investment strategies and purchases of specific securities on behalf of their clients. "We believe that the continued inflow of spot bitcoin ETFs during periods of poor bitcoin performance could be a promising indicator of continued interest in cryptocurrencies from new pools of money that ETFs have access to," said Coinbase analysts David Duong and David Han.
