If gold rose as fast as Bitcoins are rising, people would be shorting it hand over foot. They don't have that opportunity with Bitcoin, so the ship of fools sails on unimpeded until the supply of fools is exhausted, as in any bubble. Which could nonetheless take awhile and make some people very rich, provided they are smart enough to get out in time. Not everyone lost in the real estate bubble.
