How and why would the end of bitcoin (and any other cryptocurrency) occur? Value decrease? Legality issues? Different technology/ideas to supersede it?
I think the bitcoin will die if there's no people are involved. If there are no people here no one will invest and will trade and other things that can do here in bitcoin. In that case the bitcoin price will turn down into zero and there's no profit that can get. If it will happen to bitcoin will be useless and it will turn to die.
