Bitcoin spot exchange-traded funds recorded $767.33 million in net inflows during the week of March 9–13, while Ethereum spot ETFs attracted $160.82 million in the same period, signaling sustained institutional demand for the two largest cryptocurrencies.
Daily flows remained robust, with Bitcoin spot ETFs capturing approximately $53.8 million in net inflows and Ethereum spot ETFs drawing $72.4 million in a single trading session. The consistent weekly accumulation across both asset classes underscores growing confidence among traditional investors deploying capital through regulated fund structures rather than direct spot purchases.
The sustained inflows reflect broader institutional appetite heading into the second quarter, following months of regulatory clarity and the introduction of standardized investment vehicles. Ethereum's proportionally strong weekly showing relative to Bitcoin—capturing $160.82 million against Bitcoin's $767.33 million—suggests differentiated interest in altcoin exposure through regulated channels, a shift that typically precedes periods of relative outperformance.
