On March 27, 2025, Bitcoin exchange-traded funds (ETFs) continued their impressive run, recording a ninth consecutive day of net inflows, with approximately $89.57 million (rounded to $90 million in media reports) flowing into the sector. BlackRock’s iShares Bitcoin Trust (IBIT) was the standout performer, attracting $107.89 million in new capital, making it the only Bitcoin ETF to see positive inflows on the day.
Bitcoin ETF Landscape: IBIT Dominates, BITB Sees Outflows
Despite the overall positive inflow, the Bitcoin ETF market showed clear divergence. While IBIT absorbed substantial fresh funds, Bitwise’s BITB experienced $18.32 million in net outflows, partly offsetting IBIT’s gains. The remaining ten Bitcoin ETFs recorded no significant activity. Analysts suggest that BITB’s outflow could reflect profit-taking by some investors or a rotation toward the more liquid IBIT product.
Daily trading volume across all Bitcoin ETFs surged to $1.87 billion, underscoring robust investor engagement. However, total net assets for Bitcoin ETFs declined to $97.22 billion, a $1.78 billion drop from the previous day, as Bitcoin’s spot price experienced a decline. This highlights that while capital continues to flow in, price movements still heavily influence the aggregate value of ETF holdings.
Ether ETFs Continue Losing Streak, Total Assets Dip Below $7 Billion
In stark contrast to Bitcoin ETFs, ether ETFs extended their outflow trend, shedding $5.89 million on the day. Grayscale’s Ethereum Trust (ETH) led the losses with $4.90 million in outflows, followed by Fidelity’s Fidelity Ethereum Fund (FETH) which recorded $996,090 in withdrawals. No other ether ETF reported significant activity.
As a result, total net assets for ether ETFs fell below the psychologically important $7 billion threshold, closing at $6.84 billion. This marks a notable decline from recent highs and reflects persistent investor skepticism toward ether’s near-term prospects. Market observers point to subdued on-chain activity, increased competition from Layer-2 solutions, and regulatory uncertainty as key factors driving capital away from ether ETFs.
Divergent Sentiment: Bitcoin Remains Institutional Favorite
The stark contrast between Bitcoin and ether ETF flows underscores a clear divergence in investor sentiment. BlackRock’s IBIT continues to dominate, reinforcing the view that traditional financial institutions view Bitcoin as the most mature and liquid digital asset for portfolio allocation. Meanwhile, ether ETFs are struggling to attract and retain capital, as investors wait for clearer catalysts — such as network upgrades or favorable regulatory developments — before committing funds.
Looking ahead, if Bitcoin ETFs can sustain their current inflow momentum, total net assets could soon reclaim the $100 billion mark. Ether ETFs, however, will need to reverse their outflow trend to restore market confidence. Investors should closely monitor Bitcoin’s price action and ether’s fundamental developments to make informed allocation decisions.
