BlackRock continues to demonstrate its dominance in the cryptocurrency market with another day of nine-figure inflows. Namely, the world’s largest crypto fund added around $261 million worth of Ethereum ( ETH ), roughly 57,105 ETH, to its portfolio on August 27, according to data published by CoinGlass . On the same day, BlackRock bought an additional $52 million worth of Bitcoin ( BTC ), roughly 454 BTC in total. Altogether, Ethereum exchange-traded funds ( ETFs ) now hold approximately $30 billion in assets under management. Bitcoin ETFs , on the other hand, command north of $143 billion.

BlackRock and Fidelity , for instance, reported a 65% surge in assets under management last quarter alone. Large-scale buying hasn’t been limited to funds, however, as whale wallets have seen record-breaking activity too, one address accumulating more or less $3 billion in a week after selling BTC to fund the purchase. The additional surge in appetite this month was in part due to the weakening of Bitcoin , which shifted attention toward Ethereum due to its yield potential. Buying has also coincided with a price increase, as the cryptocurrency now sits above its 20-day moving average of $4,468, trading at $4,597 at the time of writing. ETH price.
