The continued institutional investments are bringing more capital to support Bitmine’s operations and continued Ether (ETH) purchases.
The company’s financing flexibility is closely watched through its market net asset value, or mNAV, a ratio that compares a company’s enterprise value to the value of its crypto holdings.
An mNAV below 1 can make it harder for companies to raise capital by issuing new shares, potentially limiting additional cryptocurrency purchases. Data tracked by Bitmine monitoring services indicated the company’s mNAV remained above 1, supported in part by continued institutional ownership.
