Out of your opinions I can assume that soon bitcoin will be able to conquer web world and businesses related to internet but I strongly believe that it won't replace fiat in our everyday life aspects, such as bills, food, transport etc.
i think many others also agree on this. bitcoin can not conquer fiat world and replace it completely and will always remain option number two in the real world.
but it can easily replace fiat when it comes to online payment. because all the options we have in online payment are bad compared to bitcoin. they all lack security, privacy and if fees don't go high we can still consider bitcoin to be cheaper.
