I used to believe that Bitcoin will die if these issues with high fees and delayed confirmations aren't solved any time sooner but I have a different perception now. With the overwhelming increase in patronage I doubt if Bitcoin will die any Sooner even if the challenges are not resolved because a lot of the new entrants are just interested in investing in Bitcoin so that they sell when the prices goes up; there are just a few that use it on the daily basis for micro payments and they are likely to encounter the delayed confirmations unlike those that have invested and holding.
