Bitcoin is never going to be extinct
I believe its consensus will be higher and higher in the future.
I can't say that bitcoin will never going to be extinct or to die because everything has an end, but for sure i believe that bitcoin will live for a long years because there are a huge possibility that everyone in the world will adopt bitcoin and it will continue to increase it's price in the future.
Every thing have the end of live and bitcoin become the end after many investor left and not interested with bitcoin, we can't say bitcoin is never going to be extinct, if bitcoin price keep stable and higher maybe have long live and bitcoin suddenly die and less investor if price down and many country have banned using bitcoin, price of bitcoin can continue how exist bitcoin several years later.
