Bitcoin and Ethereum spot exchange-traded funds (ETFs) both extended their inflow streaks on August 20, with Bitcoin products attracting $606 million in net inflows and Ethereum products drawing $221 million in fresh capital. Both Bitcoin and Ethereum ETFs have now posted four consecutive days of net inflows.

The latest August 20 ETF flows reflected continued institutional interest in cryptocurrency investment products, with both spot Bitcoin ETFs and spot Ethereum ETFs extending their winning streaks. Since spot Bitcoin ETFs debuted in the United States in January 2024 and spot Ethereum ETFs followed in July 2024, the products have become a mainstream channel for institutional exposure to the two largest cryptocurrencies by market capitalization.

Bitcoin Leads Daily Flows

On August 20 (ET), Bitcoin spot ETFs recorded $606 million in total net inflows, marking the fourth consecutive day of positive flows. The strong inflows highlight sustained investor demand for Bitcoin exposure through regulated exchange-traded funds offered by major asset managers. Bitcoin remained the primary destination for institutional capital, with inflows significantly exceeding those of other digital asset investment products.

At the same time, spot Ethereum ETFs attracted $221 million in net inflows, also extending their four-day inflow streak. Ethereum continued to draw strong investor interest, reinforcing positive sentiment toward the second-largest cryptocurrency.

Market Watch

Daily ETF flow data is closely watched as a measure of institutional participation and broader market confidence. Unlike futures-based products, spot ETFs hold the underlying assets directly, so net inflows correspond to acquisition of actual Bitcoin and Ethereum by the funds. Consecutive days of inflows into both ETF categories suggest that institutional investors remain actively allocating capital to the crypto market.
