MicroStrategy is breaking its 'never sell Bitcoin' belief. This time, they proactively sold 3,588 BTC, cashing out $216 million, which makes no sense logically. The company has $2.55 billion in cash on its books, enough to cover the next 17 months of interest payments. Even if facing liquidity pressure, MicroStrategy could easily continue raising funds through issuing common stock—an 'infinite lifeline'—instead of touching its core assets. This large-scale sell-off signals a fundamental shift in their Bitcoin accumulation strategy. The once-unshakable fortress of belief now shows cracks.
