In my own opinion it bitcoin may die if there is a world war and almost damage all things .
Second will be if internet dies ,welll bitcoins is mine and exist through online. Bitcoins storage will be spend only if there
is a internet ,however it will be a too impossible to happen now if so, how we may kill the internet .
Yes you are right.
The demolition of bitcoins seems to be now so legit hypothetical.
Bitcoins now have gained a huge amount of respect,
And vast or massive acceptance among the people.
So even I think that bitcoins dieing is very difficult.
Until there is some better technology than bitcoin invented in the market.
And people start using it.
