Financial giant Blackrock has invested a significant sum in Ethereum, buying 19,070 ETH worth $48.4 million, fueling bullish sentiment for the cryptocurrency. This purchase comes amidst signals that ETH could reclaim its previous all-time high of around $4,000, bolstering hopes of an altcoin rally known as ‘altseason’. Blackrock’s recent investment follows a period of strong inflows into Ethereum Spot ETFs, indicating increased institutional interest in the asset. 11 consecutive days of net inflow for these ETFs totaling $78.17 million underline this trend. With ETH price showing signs of recovery and breaking its recent barrier, analysts predict significant upside potential, potentially leading to a return above the $4,000 mark.
