No one knows the future so any answer would be a prediction of the possibility. I believe that Bitcoin needs upgradation to deal with high transaction fees and confirmation time. Bitcoin has a tremendous potential to acquire the huge micro transactions market but in order to do that, the fee must be less than $0.01 and confirmation time should be less than 10 seconds. If we could somehow reach this target then I do see huge potential for the growth otherwise Bitcoin would remain as a player of international funds remittance industry.
