The US spot Bitcoin exchange-traded fund ( ETF ) once again attracted $66.2 million in net inflows on September 29, continuing its recent positive trend.

Bitcoin and Ethereum ETF still recorded a total net inflow of about $63.4 million on that day, but almost all of the demand came from Bitcoin products.

BlackRock and ARK promote the inflow of Bitcoin ETF

According to Farside Investors data, Bitcoin ETF saw a net inflow of 66.2 million US dollars, which is an acceleration from Monday's 31 million US dollars, and also continues the stronger performance of these funds from last week.

The distribution of funds is also worth noting, as the demand on that day was highly concentrated. It was not the entire ETF sector that saw an influx of funds; rather, before accounting for the outflow of funds from Bitwise, BlackRock and ARK contributed nearly all of the positive financial activity.

However, the spot price of Bitcoin does not fully reflect the improvement in demand for ETF. As of press time, the bid for BTC was $83,888, which represents a decrease of about 0.17% over the past 24 hours.

Ethereum ETF ends continuous inflow

Ethereum ETF, on the other hand, showed a different trend. These funds recorded a slight net outflow of $2.8 million on September 29th, ending a series of consecutive trading days with net inflows.

According to Farside Investors data, BlackRock's ETHA experienced a capital outflow of 8.9 million US dollars, while Fidelity's FETH recorded a net outflow of 6.7 million US dollars. Grayscale's ETH product, on the other hand, saw a net inflow of 12.8 million US dollars, which partially offset the aforementioned redemptions.

Compared to the several hundred million dollars that flowed into Ethereum ETF during earlier trading days of this month, this reversal is on a smaller scale. This suggests that the latest results appear to be more of a temporary pause in demand, rather than a large-scale withdrawal.

At the time of deadline, Ethereum was trading at around $2,695.15, down by about 0.5% in the past 24 hours.
