Economist Peter Schiff has raised concerns about the legal risks associated with Strategy's Bitcoin funding model, which relies on STRC perpetual preferred stock. Schiff criticized the model's sustainability, particularly its 11.5% annualized yield, suggesting it could mislead investors and potentially lead to fraud lawsuits. Despite these warnings, Strategy, under Michael Saylor's leadership, continues to expand its Bitcoin holdings, recently acquiring 23,934 BTC, bringing its total to 780,897 BTC valued at nearly $59 billion. Strategy's funding approach, which includes issuing STRC preferred stock with a $100 par value and monthly dividends, has faced scrutiny over its long-term viability. Schiff's comments add to the debate on financing large Bitcoin acquisitions through yield-based instruments. Meanwhile, Bitcoin's price recovery above $77,000 has returned Strategy to profitability, with a reported 5.6% Bitcoin yield year-to-date. Saylor remains unfazed by the criticism, asserting confidence in the company's strategy.
