Bitcoin has two innovations in my view: 1. Technological innovation: distributed ledger with trust-less consensus. However, that innovation is largely unnecessary for almost all practical purposes, and it leads to resource use that is about a billion times higher than without that innovation (due to duplicated work and Proof of Waste). 2. Legal/process/social innovation: circumvention of rules and regulations, like Uber. Some people love that innovation, some people think it is rather harmful. Personally, I think encrypted and uncensorable flow of information is a net positive, and should be retained. Encrypted and uncensorable flow of money, not so sure.
