Amazon shareholders have submitted a proposal for the $2.3 trillion company to explore adding Bitcoin to its treasury, following similar discussions at Microsoft. This move comes amidst a broader trend of corporations considering cryptocurrency investments, with MicroStrategy's CEO Michael Saylor hinting at another Bitcoin purchase. The proposal at Amazon aims to assess whether adding Bitcoin to the company's treasury would be in the best long-term interests of shareholders. This follows Microsoft's upcoming shareholder vote on December 10, where the company's potential investment in Bitcoin will be discussed, influenced by MicroStrategy's significant Bitcoin acquisitions this year, totaling $17.5 billion.
