MicroStrategy's stock price has surged following the resumption of its bitcoin buying spree. The company, after a brief pause, is back to accumulating bitcoin, pushing its total holdings above 600,000. These holdings are currently valued at over $73 billion, further solidifying MicroStrategy's position as a major corporate holder of the cryptocurrency. The renewed investment signals continued confidence in bitcoin's long-term value by the company and appears to be positively influencing investor sentiment.
