MicroStrategy accelerated Bitcoin accumulation to 843,738 BTC via stock offerings and plans $1.5B note repurchase. Michael Saylor signaled a shift from 'never sell' to possibly selling limited Bitcoin to optimize BTC-per-share and support dividends. The stock fell 7.6% over six months, underperforming the S&P 500, amid softer results and leverage concerns. Critics call the strategy a Ponzi needing 30% annual BTC growth.
