I am agree that bitcoin can not die, I thrust that bitcoin will life forever. It is thecnology is very very ingenoius. I am sure that bitcoin is very very usefull in the future. If world war happen bitcoin is needed to transferring money with anonimity so the goverment or the enemy cannot stop our economy activity.
I don't know about that anymore. It is not about bitcoin, it is about everything - economic wise.
People are convinced that economic stability, currencies, order, technology is stable and accept it as paradigm.
With bitcoin, or cryptocurrencies in general - since it is totally new concept - it is a little harder to estimate longevity of the projects.
But saying that Bitcoin will be forever with us it is pure overstatement.
