> Social media is a shit show of shills and propaganda from all angles. So really only time will tell. I'm curious about historic precedents - I really don't know much about the history of currency. There must have been analogues in the past - I know Isaac Newton famously went to war with counterfeiters, but that (and vague memories of hearing about bank currency in the US) about the only instance of currency competition I know of. Anyone want to recommend a quality book on the topic?
