MicroStrategy's stock took a hit, dropping over 8% after its recent $209 million Bitcoin purchase. The company, known for its aggressive Bitcoin strategy, made the buy just before Nasdaq opened, causing shares to dip from $318.89 to $302.09 in an hour. Despite a slight recovery, shares closed at $302.96 and fell further in after-hours trading to $293.59. Concerns are rising over MicroStrategy's heavy leverage and plans to increase authorized shares. While the stock is up significantly since January, some experts predict potential volatility ahead.
