US spot Bitcoin exchange-traded funds recorded about $8.05 billion in trading volume across the five sessions through Friday, marking the lightest full trading week for the products since October 2024.

Spot Ether ETFs, by contrast, brought in new money for a third consecutive week, continuing a recent period in which Ether products have attracted stronger inflows than their larger Bitcoin counterparts.

Bitcoin ETF turnover falls sharply

According to SoSoValue data, weekly trading volume for US spot Bitcoin ETFs fell 14% from $9.37 billion in the prior week. April 2025 saw a lower weekly total, but that period included only four trading sessions because US markets were closed for Good Friday. Measured against complete five-day trading weeks, the latest figure was the lowest turnover since the week ending October 11, 2024.

Trading volume and fund flows measure different parts of ETF activity: volume captures shares changing hands on exchanges, while net inflows and outflows reflect money entering or leaving the fund structure. The latest week showed both weaker turnover and only modest net demand for Bitcoin products.

BTC traded around $64,000 for much of the week, below the highs reached late last year. With limited price movement, trading activity across the Bitcoin ETF market slowed.

The funds still posted net inflows of about $33.8 million for the week, extending their inflow streak to three weeks after a record eight-week run of outflows ended in early July. The latest inflow total was the smallest of the three-week stretch, following $75.7 million the previous week and $197.4 million the week before that.

The weekly total masked a sharp late-week reversal. By Wednesday, the funds had taken in about $499.1 million. Investors then withdrew $225.2 million on Thursday and another $240.1 million on Friday, erasing most of the gains accumulated earlier in the week.

BlackRock’s IBIT, the largest fund in the category, accounted for a large share of the reversal, losing $414.7 million over those two days and ending the week down about $95.5 million. The ARK 21Shares Bitcoin ETF and Grayscale’s Bitcoin Mini Trust helped offset part of the outflows, drawing about $85.8 million and $78.1 million, respectively.

Ether ETFs continue to outpace Bitcoin funds

Spot Ether ETFs added about $103.9 million during the week, more than three times the amount that flowed into spot Bitcoin ETFs and enough to give the Ether group a third straight week of inflows. Ether products have now outpaced Bitcoin funds for two consecutive weeks. In the previous week, Ether ETFs brought in $105.4 million compared with $75.7 million for Bitcoin ETFs.

As of Friday, Ether ETFs held $10.17 billion in net assets, roughly one-eighth of the $77.82 billion held by Bitcoin funds. Despite that size gap, the two categories have raised nearly identical amounts over the latest three-week period. Ether products brought in about $293.8 million, compared with $306.9 million for Bitcoin funds.

BlackRock’s iShares Ethereum Trust accounted for $96.3 million of the Ether inflows. Grayscale’s Ethereum Mini Trust added $9.9 million, while Fidelity’s FETH recorded $6.2 million in outflows. Ether ETFs generated $2.78 billion in trading volume for the week, equal to about 35% of the volume traded by Bitcoin funds.

The relative strength of Ether inflows is notable because the Ether ETF market remains much smaller than the Bitcoin ETF market by assets. Sustained flows into the smaller category can therefore stand out even when dollar totals remain far below Bitcoin funds’ overall asset base.

Recent inflows have not reversed the year’s overall losses. Bitcoin ETFs remain down about $5.23 billion since January, while Ether funds are down about $1.15 billion. In July, Ether has led the rebound with about $337.7 million in inflows, compared with $234 million for Bitcoin.

The two ETF groups ended their eight-week outflow streaks on July 11, when they added a combined $281.8 million. That recovered only part of the approximately $9.46 billion that had been drained over the preceding two months.

Earlier, Bitcoin funds ended an unprecedented 13-day withdrawal streak on June 5 after more than $4.4 billion in redemptions since mid-May. ETH ETFs ended a 17-day slide on the same day.

Cryptopolitan previously reported that on June 5 alone, $326 million exited Bitcoin funds, including $214 million from BlackRock’s IBIT. CoinShares data also showed that professional investors reduced their Bitcoin exposure by 17% in the first quarter.

Bitcoin was trading at around $64,368 on Saturday morning, while Ether traded at around $1,875, according to CoinGecko’s aggregated data.
