I believe that nuclear war is not an absolute factor to destroy Bitcoin. Of course, if such an extreme situation occurs, human beings will disappear. Bitcoin is for human beings, so its existence is meaningless. I am also very puzzled, why There are such doubts. If it is because the current market sentiment is depressed and you can't find the direction? Or because of a loss of confidence in Bitcoin. Don't stress too much. In the world of digital currencies, this is all normal.
