Following five consecutive weeks of net withdrawals totaling approximately $5.39 billion, U.S.-based Bitcoin exchange-traded funds (ETFs) experienced a sudden change.
For the week ending March 21, Bitcoin ETFs registered a net inflow of $744.4 million—the largest weekly influx in eight weeks—a sign of renewed investor confidence in cryptocurrency-focused investment vehicles.
BlackRock’s IBIT Dominates as Investors Return
BlackRock’s iShares Bitcoin Trust (IBIT) is one of the biggest contributors to this surge, with $537.5 million in investment absorbed by it in the week. Fidelity’s Wise Origin Bitcoin Fund (FBTC) also contributed highly, with $136.5 million inflows.
The shift in sentiment follows a period of sustained outflows across all exchange-traded products, which affected the overall market performance. The renewed capital inflow into IBIT and FBTC is a proof of a potential shift in institutional and retail investor interest for Bitcoin exposure.
Ethereum ETFs Struggle Following Continued Outflows
While there was positive Bitcoin ETF momentum, Ethereum-based funds have continued with outflows. For the fourth straight week, Ethereum ETFs saw a combined net outflow of $102.9 million, with BlackRock’s iShares Ethereum Trust ETF (ETHA) accounting for $74 million of the total.

The difference between Bitcoin and Ethereum ETFs shows differing market sentiment toward the two leading cryptocurrencies. While Bitcoin ETFs benefited from a reversal in investor confidence, Ethereum products remain under pressure.
Market Signals and What’s Driving the Shift
The rebound in Bitcoin ETF inflows shows investor sentiment flip, which might be fueled by changing regulatory climates and macroeconomic conditions. The recent assurances from President Donald Trump of flexibility on tariffs in the future may have led to this latest optimism.
Besides, Federal Reserve Chairman Jerome Powell’s comments describing the impact of tariffs as “transitory” and the possibility of a 0.5% interest rate cut in the second half of the year may have also supported the improved outlook for Bitcoin-focused investments.
The comparison of the performance of Bitcoin and Ethereum ETFs proves the changing nature of the cryptocurrency investment. Investors will likely continue to monitor macroeconomic signals and regulatory developments for further clarity on market direction.
