It's not possible because bitcoin is spread world wide and one single person can't stop bitcoin network. Anyway if it stops then we have to give up and return our home with water in eyes.
Bitcoin can disappear in future but not very soon as bitcoin is still in its primary stage and it has so many things left to offer to its users and we will witness that in coming years.
no i am not agree with you bitcoin is not going to disappear at any stage, it is becoming more and more stronger as time passes because more and more people are entering in the world of bitcoin and now is becoming an essential part of our life, it is going to replace fiat currency in future and then all the people of the world will be using bitcoin instead of fiat currency.
