United States spot Bitcoin exchange-traded funds (ETFs) have maintained positive flows for eight out of the past ten consecutive trading days. 

On Aug. 20, the ETFs saw an aggregate inflow of $88 million, their highest for two weeks according to preliminary data from Farside Investors.

It marks 80% of the past fortnight’s Bitcoin ( BTC ) ETF trading days seeing positive flows, with just two days — Aug. 9 and Aug. 14 — seeing an outflow.

BlackRock’s iShares Bitcoin Trust (IBIT) led the pack with an inflow of $55.4 million, bringing the total net inflow for the product since its launch in January to $20.5 billion.

IBIT, which surpassed longtime Bitcoin ETF player Grayscale in terms of assets under management (AUM), has not seen an outflow day since May 1 — the only day of net outflows it has had since it launched in January.

The Ark 21Shares Bitcoin ETF (ARKB) was a close second with an inflow of $51.9 million on Aug. 20.

The Grayscale Bitcoin Trust (GBTC) saw a net outflow of $12.8 million, and the Bitwise Bitcoin ETF (BITB) also saw minor net outflows of $6.5 million. The remaining funds saw zero flows.

Grayscale’s flagship fund has lost $19.6 billion since its conversion to an ETF seven months ago. Its lower-fee Bitcoin Mini Trust (BTC) has gained just $288 million since its launch on July 31.

It was also recently reported that 60% of the largest hedge funds in the United States have exposure to Bitcoin ETFs, according to Sam Baker, researcher at investment firm River.

Spot Ether ETFs , meanwhile, have seen five out of the past eight trading days outflowing assets.

Aug. 20 saw the nine newly launched spot Ether ( ETH ) ETFs post joint net outflows of $6.5 million, making their fourth consecutive day of outflows, per Farside Investors.

BlackRock’s iShares Ethereum Trust (ETHA) had $26.8 million in net inflows, not enough to outpace the $37 million net outflow from Grayscale’s Ethereum Trust (ETHE).
