The concurrent inflows into BlackRock’s IBIT and ETHA could signal renewed demand for crypto assets. Furthermore, the firm’s crypto portfolio recorded a net cash outflow of roughly $12.45 billion in early June, as Finbold reported.
Institutional investors may be shifting to crypto assets amid analysts’ warnings of a potential post-IPO (Initial Public Offering) bust, as Finbold reported. Moreover, Bitcoin and Ethereum have been trapped in a multi-month bear market, fueled by whales’ sell-off.
Bitcoin and Ethereum prices rebound amid BlackRock’s renewed demand
As BlackRock’s investors signal renewed demand for Bitcoin and Ethereum, the two crypto assets have attempted to reverse. Over the past seven days, BTC price climbed 2.47%, trading at $63,440 at press time.

As such, if BlackRock’s investors continue to accumulate more BTC and ETH over the coming days, a potential crypto reversal could occur. However, if the firm’s investors continue to liquidate, a fresh crypto sell-off could be inevitable.
