Since October, the National Center for Public Policy Research (NCPPR), a US think tank, has submitted shareholder proposals asking Microsoft and Amazon to consider investing in bitcoin, arguing that it would insulate the companies and their investors from inflation. The group says more bitcoin proposals are in the pipeline, while also arguing that promoting bitcoin adoption is in line with its "pro-freedom" agenda, as cryptocurrencies are largely outside government control. Microsoft shareholders have voted to reject the bitcoin investment proposal, and it remains to be seen whether Amazon will adopt the strategy. (The Washington Post) Previously, on December 13, the NCPPR proposed that Amazon add bitcoin to its financial reserves. The NCPPR believes that bitcoin can be used as a hedge against currency depreciation, but it is still uncertain whether Amazon will adopt a more innovative strategy.
