It will need lots, lots of confidence from the board to even consider implementing such steps ahead.
Surely, they would be able to see the potential in Bitcoin, but they would consider risks very carefully, due to them not using it for such matters beforehand.
I do think the money we are talking about are huge, but it's a tear drop for the Meta, imo.
I searched online news about Ethan Peck's proposal for bitcoin reserves as an effort to combat inflation and maybe he has a strong belief in bitcoin as a hedge so he dares to propose the proposal but if the board of directors does not approve then it seems difficult to implement the proposal because as far as I know every director must have different beliefs from his idea. Mark Zuckerberg himself as CEO is starting to be indirectly interested in bitcoin so this step should be good to implement.
Thus more and more companies are starting to involve their portfolios in bitcoin investments and most of them argue to protect the value of their assets because talking about inflation that could possibly get out of control at any time so it does not affect the company's financial value indirectly.
