Bitmine Immersion Technologies, co-founded by Tom Lee, is set to launch a preferred stock offering aimed at raising $300 million. The firm will issue 3 million shares of Series A Perpetual Preferred Stock, each valued at $100, with a 9.5% annual dividend paid weekly in cash, pending board approval. This move aligns with strategies employed by other cryptocurrency treasury firms, such as Michael Saylor's Strategy, to secure funding amid a challenging market environment. Bitmine has aggressively acquired over 5.3 million ETH, representing about 4.5% of Ethereum's circulating supply, although this investment is currently facing an estimated $9 billion unrealized loss due to falling ETH prices. The preferred shares will be traded on the New York Stock Exchange under the ticker BMNP, subject to regulatory approval. The offering highlights the ongoing efforts of digital asset firms to diversify funding sources as they navigate market volatility.
