Nothing new under the sun. As a first-order approximation, all currencies in history have ultimately disappeared or stopped working as currencies, from Roman denarii to Italian Florins to Brazilian Cruzeiros to Rwandan Dollars to Venezuelan Bolivares.[a] Currently there are 190+ countries on earth, most of which have their own currency. Only a fairly small number of those currencies are widely considered stable. The rest are probably destined for the dustbin of history.
