At the time of the update, ETH’s price had pegged the overall value of BitMine’s ETH reserves at $6.6 billion. However, the largest altcoin by market cap retraced over 2% in the last 24 hours to trade at $4,225.03 as of 1:15 a.m. EST.

BitMine currently ranks 10th among the 5,700 US-listed stocks, BitMine said. It also has around $6.4 billion in daily trading volume, which ranks it ahead of JPMorgan (JMP) and just above Alphabet (Google), it added.

Ethereum ETFs Suffer Second-Biggest Outflows Since Launch

BitMine’s continued accumulation of ETH has not been able to positively impact the altcoin leader’s price in recent days. This is likely due to the outflows from US spot Ethereum ETFs (exchange-traded funds) this week.

On Aug. 18, investors pulled $59.3 million out of the products, marking the end of a multi-day inflows streak, Farside investors data shows.  It was also their second-biggest net daily outflows since launch last year.

On the day, $196.6 million was withdrawn from the funds. The only day the funds recorded more outflows was Aug. 4, when $465.1 million was pulled from the products. 

BlackRock’s ETHA posted the largest outflows yesterday with $87.2 million exiting the fund’s reserves. 

The next biggest outflows were posted by Fidelity’s FETH, which saw $78.4 million in outflows. Bitwise’s ETHW, VanEck’s ETHV, Franklin’s EZET and Grayscale’s ETHE saw net daily outflows of $0.9 million, $4.8 million, $6.6 million and $18.7 million, respectively.
