Spot Bitcoin and Ethereum exchange-traded funds in the United States continue their streak with a second consecutive day of positive inflows this week.

According to data from SoSoValue, the 12 spot Bitcoin ETFs recorded a total inflow of $38.94 million on Aug. 13, representing a nearly 40% increase from the $27.87 million recorded the previous day.

BlackRock’s IBIT fund led with $34.6 million in inflows, bringing its total since launch to $20.36 billion. It was the only Bitcoin ETF to see inflows for two consecutive days.

Other notable inflows included $22.6 million into Fidelity’s FBTC and $16.5 million into Bitwise’s BITB. These gains helped to counterbalance a $28.6 million outflow from Grayscale’s GBTC, which has seen total outflows of $19.49 billion since its inception.

The remaining Bitcoin ETFs did not record any activity on that day.

Trading volumes for Bitcoin ETFs were slightly lower at $1.18 billion, down from $1.3 billion on Aug. 12. The cumulative net inflows into spot Bitcoin ETFs stood at $17.4 billion.

In contrast, the nine spot Ethereum ETFs saw a significant uptick in investor interest, with net inflows reaching $24.3 million on Aug. 13, a notable increase from the modest $5 million recorded the previous day.

According to data from SoSoValue, BlackRock’s ETHA led the charge once again, with $49.1 million in inflows following a day of no flows.

Fidelity’s FETH and Invesco Galaxy’s QETH also saw inflows of $5.4 million and $0.8 million, respectively. This was the first day of inflows for Invesco’s Ethereum ETF since its launch.

Grayscale’s ETHE fund saw an outflow of $31 million, bringing its total outflows to $2.32 billion since launch.

Despite the inflows, the trading volume for Ethereum ETFs dropped significantly to $190.76 million. Overall, these funds have experienced cumulative net outflows of $376.67 million to date.

At the time of writing, Bitcoin (BTC) was exchanging hands at $60,786, while Ethereum (ETH) stood at $2,726.
