BTC Spikes Slightly as Bitcoin and Ethereum ETFs Maintain Persistent Inflows

At the time of writing, Bitcoin is priced at $115,692, following a 0.7% uptick in the past 24 hours. The flagship crypto is oscillating between $114,509 and $115,995, highlighting potential price stabilisation around the price range. Notably, BTC’s market metrics have remained impressive despite Peter Schiff’s most recent criticism.

On September 14, the popular Bitcoin critic tweeted that the Fed is on the verge of making a significant policy mistake by cutting rates into rising inflation. He noted that gold and silver have broken out, while Bitcoin continues to lose strength.

Schiff stated:

“Gold and silver have broken out, with the rally finally confirmed by mining stocks leading the way. Yet instead of breaking out, Bitcoin is topping out. Time to change horses, HODLers.”

Despite continuous criticism, Crypto2Community reported on September 16 that Next Technology plans to expand its Bitcoin treasury through a $500 million common stock sale. Strive also unveiled its new leadership board and fundraising programs aimed at establishing one of the largest Bitcoin treasuries.

BlackRock Drives Ethereum ETFs Inflows

Only three Ethereum ETFs traded on September 15. The remaining six, including Grayscale Mini Ethereum ETF (ETH), Bitwise Ethereum ETF (ETHW), and VanEck Ethereum ETF (ETHV), had neither inflows nor outflows. BlackRock Ethereum ETF (ETHA) and Grayscale Ethereum ETF (ETHE) added $363.19 million and $10 million, respectively. In contrast, Fidelity Etherum ETF (FETH) lost $13.46 million.

Overall, Ethereum ETFs’ cumulative net inflow slightly increased from $13.36 billion to $13.72 billion. However, other cumulative metrics, including the total value traded and total net assets, dropped from $2.55 billion to $2.09 billion and $30.35 billion to $29.72 billion, respectively.

ETH Records Slight Drop

Despite Bitcoin and Ethereum ETFs’ consistent daily net inflows, ETH is down 0.5% in the past 24 hours. It is trading at $4,506 and fluctuating between $4,476.73 and $4,538.16. Ethereum’s Fear & Greed Index has remained neutral, with a bullish sentiment, and a medium volatility at 3.35%.
