The strong inflows into iShares funds contrast with outflows from traditional trusts, suggesting a preference shift among investors. These movements, however, are part of broader investment strategies and do not necessarily indicate short-term price trends. Rather, they provide insights into how institutional investors are collectively engaging with crypto assets within a regulated framework. Any change in the macro strategy or the decision to sell profits or redistribute funds can lead to flow differences.
