Most Johnly of HenriesThe largest harm of the cryptocurrency world, besides people losing money via scams (they're taking crazy bets and I don't have much sympathy), is that they vacuum energy and attention away from "regular" decentralization initiatives that simply want to distribute power away from monolith tech companies into the hands of ordinary developers and people, without also inventing crazy new economies and political systems in the process. You don't need a cryptocurrency to beat Twitter.
Drew Wings ✅@johnhenry agreed and blockchain might be a way to add more security/authentication to the federated model so ppl can verify themselves across multiple instances.
