Five-Day Streak: Bitcoin and Ethereum ETF Inflows Top $492 Million

Investors are adding significant funds to regulated Bitcoin and Ethereum exchange-traded funds (ETFs), marking five consecutive days of net inflows. According to WuBlockchain, spot Bitcoin ETFs pulled in $307 million on August 21, while spot Ethereum ETFs added $185 million.

This streak suggests that the buying is not limited to a single narrative, such as a flight to bitcoin quality, and indicates institutional investors are re-entering exposure through regulated wrappers rather than waiting for spot exchanges to show stronger momentum.

The consistency of these inflows carries different information than size. A $307 million daily inflow is not historically extreme, but the fact that it has been consistent over five days stands out, especially considering August is a month when many institutional desks run lighter staffing.
