Microsoft internal document suggests 1% Bitcoin

Bitcoin is a more volatile asset, at the moment, than corporate bonds, so companies should not risk shareholder value by holding too much of it. However, as Bitcoin is an excellent, if not the best, hedge against inflation and corporate bond yields are less than the true inflation rate, companies should also not risk shareholder value by ignoring Bitcoin altogether. At minimum, companies should evaluate the benefits of holding some, even just 1%, of its assets in Bitcoin.

Between 1%-3% I said !
