Do not really care about their discussion of a 1% (wow!) spent on bitcoin.
Vote away...one way or another.
MSF buying Bitcoin would probably be the "ok" for other big businesses to do the same. It could mark the beginning of the run on BTC by institutions ...after which countries will follow.
Nothing is a signal to anyone...Saylor was buying bitcoin for years...and who followed?
A small japanese company plus skittish Tesla?
I know, they are few others, but on a VERY limited basis.
I don't think you can equate Tesla buying Bitcoin to Microsoft buying Bitcoin. Elon has a reputation for doing off the wall things that others don't understand. Microsoft is a pretty well established and reputable company.
At the very least... I don't see how it would be a bad thing for adoption if Microsoft was to buy... even a little bit.
