The target market for Bitcoin use by Microsoft is XBox gamers, many of whom are under 18 years of age. This demographic doesn't have credit cards. Bitcoin will become the defacto savings and payment method for this demographic. Cash doesn't do them any good, as they can't spend it online. Bitcoin is the answer.
Microsoft has capitalized on something big here. The under-18 demographic has no way to legally spend fiat online. Now they can spend Bitcoin. Soon the under-18 demographic will begin keeping their funds in Bitcoin, as it's trapped in unusable form when left as fiat. Bitcoin will grow from this. Add to this the powerful educational effect of indoctrination at an early age, and we have a very bullish long-term effect for Bitcoin.
Interesting, until you think it through:
BTC is not spent directly--it must be added to your MS account.
BTC must be purchased--why would a kid steal mom's credit card to shop for BTC @ circle.com, when he could fund his account directly?
finally, what's wrong with conventional way of doing things?
