You could buy GM stock for months after they announced it was going bankrupt (making the stock = 0). As I recall, it was selling for more than 0.50 cents. If something really terrible did happen to a crypto-currency (and I don't know and I can't predict) there would be a lot of people that would still want them because they used to be worth so much. It is human nature. That is just an observation about human nature. I have no idea what will happen with the price of anything.
