FTFY... paper money will still be required.
Yeah of course we will still have paper money but I imagine that bitcoin is very attractive for international money transfers, and it will take over as the main currency used by everyone.
Why would anyone need btc while MasterCard&Visa can do everything (and more) that btc can? (onlinewise)
The only advantage of using btc is anonimosity. (which is pretty much ded also, you can not btc>usd huge amounts of coins without getting caught by gov) Nothing else.
