i think it can't because bank works in the country to make circulation of money in that country, and all people can't use bitcoin, we need offline currenciies like money too to use it offline and when internet is down or something else, maybe someday bitcoin can make credit card dissapear
However, as per my know, Facebook and Google are want to create an internet network coverage worldwide. I think if these largest company can do that in future, the future use Bitcoin every where can happen.
