And dollar is backed by nothing but trust and actually dollar is nothing but numbers in computers: some of dollars has paper form but it is minority as far as I know. I am not saying that you are not right. I personally see why bitcoin might succeed. By some aspects it already succeeded having in mind that their total value is 200 milion dollars (am I right?). Question is if people will trust more centralized currencies or decentralized.
