I'd say the goal shouldn't be to convince the crypto fanatics. It should be building awareness towards what cryptocurrencies and technologies based on the blockchain actually are and why they can't at all achieve what people invested in crypto promise. For the people that are vulnerable, politicians and organizations, in short: people being manipulated by outright false promises and deliberately vague "arguments" (like there always being that one coin nobody uses which of course solves all the problems of the topic at hand). Crypto doesn't offer much in terms of decentralization, but one thing it does decentralize incredibly well is advertisement and evangelism because every single cryptocurrency holder has a true financial incentive to spread overhyped and false information around anything remotely connected to blockchain technologies in order to drive up the price.
