If Bitcoin would die tomorrow then I would have to quit with Bitcoin and maybe find something else instead of Bitcoin. I would have a hard time at first but eventually you will have to accept it.
But I do not think that Bitcoin is going to die anytime soon.
You made right. There is no point wasting time talking about the possibility of bitcoin dying.
Most people that continously talk about bitcoin dying are just the pessimistic set of people in my opinion. If you are optimistic, you will surely believe that Bitcoin will never die also there will not be any possibilities for that.
