How could bitcoin disappear? I don't think that could happen. It can reduce in value to 0.01 cent but that doesn't mean it will vanish and not be available to be used as a currency. Nothing in the online world truly disappears. That is the number one rule of the internet.
I think bitcoin can disappear. you should be wondering why. yeah, bitcoin can disappear when something so-called electricity will disappear. there will be time no light and technology in the world. I think Albert Enstein had said that. so I think it should be the death of bitcoin. IMO
well, electricity is never going to go away. and even thinking it is strange. it can only go away if there is a world war III and there is a nuclear winter, even then it may not go away. so there is no real way that your thing can happen at all.
