bitcoin will never die
It might. It will. But I dont think we are still alive when that happens. Maybe we will die first before bitcoin comes to an end. So better make money out of it while we are still here.
Bitcoin may live forever, it might be immortal or one day it will meet its end but one thing for sure its going to take a long long time before that ever happens. Therefore, keeping faith in bitcoin and earning as much as we can from it is a clever way.
