From mid-July up until the end of August, Ethereum ETF dominance and mixed macroeconomic signals in the U.S. saw investors move away from BTC.
This certainly played a role in suppressing BTC’s price amid a broader market shakeout.
However, with anticipation of positive news from the U.S. Federal Reserve this month, as well as news that leading BTC ETF fund issuer, BlackRock, is considering tokenizing its many ETF offerings, institutional attention has returned to the premier crypto, for now.
Bitcoin’s price has responded well to this upward momentum and is trading up 2.22% for the past 7 days at $115,001.
Ethereum ETFs
As per SoSoValue, Ethereum ETFs recorded $113.12 million in daily total net inflows on Sept. 11, marking day four of a modest inflow streak that now totals $328.82 million.
Minus the outflows at the start of the week, this brings ETH ETFs’ weekly total net inflows to $232.14.
