Bitcoin ETF outflows remained relatively smaller compared to ether ETFs.
U.S. exchange-traded funds (ETFs) tracking ether (ETH) experienced $401 million in net outflows in March, erasing the gains accumulated in the first two months of 2025.
These withdrawals account for nearly 6% of the $6.77 billion in total assets held by spot ether ETFs, according to data from SoSoValue. Positive inflows were recorded on only one day this month—March 4—when $14.58 million was added. In contrast, January and February saw inflows of $101 million and $60 million, respectively.
Spot bitcoin ETFs also saw withdrawals, with $893 million in net outflows in March. However, relative to their $94.35 billion in assets under management, this represented just 0.9%. Despite these outflows, bitcoin ETFs remain net positive for 2025 after attracting $5.25 billion in January.
This divergence reflects the broader market trends. Since March 1, ether has declined by approximately 8.5%, while bitcoin has risen by over 3%. Year-to-date, ether has fallen more than 37% to around $2,080. Meanwhile, bitcoin has performed better, declining only 7.5% to about $87,300. The broader CoinDesk 20 Index also dropped 21% during this period.
Despite the recent sell-off, ether ETFs have maintained a net inflow of $2.42 billion since their inception. However, this figure pales in comparison to the $36.05 billion accumulated by bitcoin ETFs, underscoring the stronger investor preference for BTC over ETH.
