If value is not at all tangible and is based on a belief system then value can be stored in just about anything. the only reason gold price seem to have stability is because it is centralized, controlled and in the hands of a few. Bitcoin is a lot safer to hold than most if not all government currencies that exist today.

If the government fucks up the currency goes down and the community belief system that gave the currency value goes with it.

bitcoin has no government to fuck up the belief will fluctuate so will the value and so will the price. bitcoin is gonna be around for a while
