Doubling Down on Ethereum Exposure
Ark’s reinvestment into Bitmine Immersion (BMNR) signals a strategic pivot toward Ethereum-linked assets.
- Bitmine is currently the largest ETH-holding public company, with over 560,000 ETH in its treasury
- In late June, BMNR stock skyrocketed from $12 to $160 — a 1,200% rally
- However, it has since corrected to $35, presenting what Ark sees as a deep value opportunity
