No neither its dead nor dying. Bitcoin has a great future and it will grow its value in coming years Once the Government start accepting as a currency it will grow more and that would directly increase its value so i don't think its dying for next 15 to 20 years atleast.
But how are you so sure that government will acppeted our bitcoin is this world? There is so many things that they must do before they are going to aceppt it and I dont think they will do that. There is fiat that government control so I dont think its value will rise with this kind of way
