BlackRock recently made a big move, increasing their holdings by 3,198 BTC and 5,114 ETH at once. Looking at these numbers, it's clear why Bitcoin and Ethereum have been able to rebound so strongly recently. Institutional investors' buying indeed can boost market sentiment. However, to be honest, whether the market can continue to rise mainly depends on whether more funds can be attracted to enter. Only when the market maintains an upward trend will investors have the confidence to add positions; this is the basic logic of the market. From BlackRock's recent actions, it shows that large institutions still have confidence in mainstream cryptocurrencies.
