If Bitcoin would die tomorrow then my will to continue using Bitcoin would also die because I do not see a reason on why to keep hanging on to it.
I would go on with my live and just be happy with the money that I have made from Bitcoin so far.
I don't think that will happen sooner, the journey has still begun and it has a long way to go and once it reaches everywhere we will see major growth in adoption level.
But it will not gonna happen by looking on the current condition and importance of bitcoin in the market because bitcoin become more and more popular day by day, but no one know exactly what will happen in future. And if bitcoin die then everyone who are a part of bitcoin will stop using it because they don't have opportunity to earn from it.
