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.
I strongly agree on your opinion that, no one knows the future so any answer would be a prediction of the possibility, and I also believe that Bitcoin needs upgradation to deal with high transaction fees and confirmation time. And adding also my opinion that, No one can say for sure so i would recommend not making your decisions based solely upon this thread. In addition, bitcoin will be alive, as long as several computers with the program running on them continue to work. On the other hand, no one can predict that right because price of bitcoin is unpredictable.
