I don't think that everything is a bubble because if everything is a bubble then a lot of people are now complaining about it because of being over priced and even bitcoin does not have bubble price because it has a reason and root of cause why it is very expensive now and that is because of the demand and the progress of bitcoin in overall.
Probably every price rise do happen only with pumping because traders alone making those decisions to take some commodity's prices in to new level and which can be termed as bubble. Practically traders will be having some view to speculate how big the prices will go. I am not finding any wrong with that because with their available options/resources, they are doing that.
After the pump, the new investors coming into market to ensure the bubble gets realization.
