One of things about a 'bubble' is unfortunately that there isn't an exact way to determine what is and isn't a bubble prior to it bursting or when it finally levels off a bit because it reached an equilibrium of price and perceived value. After it levels off or busts you will have groups saying "I told you so" giving you the same 'evidence' they used now to support their claim. People that are 'sure' they know which this is should invest in either its success or failure, as arguing with people and trying to convince them you are right does little besides potentially increase the number of people you would have to share your profits with.
