Some idiots like you might not care. But those who are doing the ground job of taking bitcoin mainstream, do care.

How many people do you figure bought bitcoins because Microsoft started accepting it? One, two...three?Actually I think a lot more than that. Not because they are using Microsoft products and want to buy them with Bitcoin, but because Microsoft is a big company which is talked about in the news 24/7 and if such a big company is related to Bitcoin somehow this is a good thing for
BTC.
