Anyway it is their loss. Lots of people changes their minds in the past. Maybe Microsoft will too.
at this point i don’t think they will change their mind what else do they need for them to think of bitcoin as useful and worth investing into? bitcoin already reached $100k and is being promoted by the us government so if they wanted to take bitcoin they would have done by now so the fact that they didn’t means they really have no intention of doing so now or in the future
