Joe Raedle/Getty Images News Does Michael Saylor want to own every Bitcoin (BTC-USD) ever created? Fresh off the heels of a $500M debt sale - proceeds of which will be used to buy bitcoins - Microstrategy (MSTR) files for an at-the-market equity offering of up to $1B. Microstrategy owned more than 90K bitcoins prior to the just-closed $500M capital raise. Adding in another $1B would allow the company to buy roughly 37.5K coins at $40K each. MSTR is down 1.4% after hours. Bitcoin is trading a hair above $40K, having breached that level today for the first time in a few weeks after Elon Musk over the weekend capitulated on his Bitcoin bearishness.
