What happens to the value of bitcoin if the dollar goes to 0? Will bitcoin also loose value because the dollar is worthless? yes, there would probably be other things to mind like world war, full panic, no internett and so on. But set these things aside. How much would a sack of potatoes cost, and with what could I buy these potatous witth(gold/bitcoin/chickens/etc.)?

Any ideas? and any ideas on how bitcoin could be independant of the dollar, or other fiat?
