If more country don't accept it. And also the things that could have an destructive effect on Bitcoin could be a collapse of the Internet, A global Power outage, The sudden disapearance of technologie through a global catastrophy.
In truth my friend, at the start no country have accepted Bitcoin yet but it did not end. So why are you implying that it will end if that would ever happen?
All of that would only happen if a serious phenomenon happened. I want to think sci-fi-ish here so, more like alien invasion, zombie apocalypse, and even war. I think war would be the closest thing for this. If the war resulted a mass destruction to the world, then eventually we will lose this technologies you've just mentioned.
Well I think bitcoin is now stable with high price in market and many countries have accepted bitcoin and some of them make bitcoin legal so Im sure that end of the year bitcoin will be accepted by more countries so bitcoin also faced a lot of forks in past and now bitcoin now very well how to fight against forks so I believe no one can end bitcoin.
