Cathie Wood, founder of ARK Invest, has backed Quantum Solutions, Japan's pioneering Ethereum Treasury firm, which recently acquired 2,365 ETH over a week. This acquisition positions Quantum Solutions as the holder of the largest Ethereum Digital Asset Treasury outside the United States. The firm plans to continue expanding its Ethereum reserves, highlighting the increasing institutional interest in Ethereum as a strategic investment. Meanwhile, Ethereum's total value locked (TVL) is approaching $100 billion, although the cryptocurrency is facing challenges in maintaining a price above $4,100 due to market volatility.
