MicroStrategy becomes the first publicly traded company to adopt Bitcoin as its primary treasury reserve asset, announcing on August 11, 2020, the purchase of 21,454 BTC for $250 million at an average price of ~$11,653 per coin. CEO Michael Saylor, a former Bitcoin skeptic turned maximalist, argued that holding cash was "like holding an ice cube." His move would inspire hundreds of companies to follow and pioneer the corporate Bitcoin treasury strategy. MicroStrategy (later renamed Strategy) would continue buying, eventually holding over 500,000 BTC.
