At the risk of killing a sacred cow or two, and being murdered myself in the process: Cryptocurrencies have no intrinsic worth. They have no material existence. They are backed by nothing at all. They are merely numbers in a machine. I believe that in time the cryptocurrency craze of today will be looked at in the same way we look at the Dutch 'Tulipmania' of the 1600s.
