the hard reality...
while bitcoin doesnt come with a killer app that will turn it simpler in every way than fiat-c, it will stay 'zombie'.
i'm not with those that believe that bitcoin need a iller app, i changed my mind on this matter, because bitcoin isn't applae or a brand, it's a mean of payment, a completely different thing
bitcoin itself is the killer application, in the sense that it revolutionises the way payments can be done, in comparison for fiat, so bitcoin is the killer application of money
