You have to set it in something. People (and I imagine businesses) usually rush to convert it to some other more stable store of value. Today they'd probably rush for US dollars if they had access(1). I remember reading up on how in the immediate period of postwar Germany the Reichsmark was obviously inflated to nothing. People horded physical goods, any goods they could get their hands on. The result was shortages of everything. If you needed to buy anything, you'd exchange your goods for American cigarettes or bottles of booze that you'd then exchange for what you're actually looking for. You see similar "economies" in prisons. In the case of countries with active hyperinflation, if you use the currency at all it would be for a daily transaction. You'd hope to not hold any of it by the end. I do recall a story of how in Zimbabwe (before the hyperinflation got absolutely ridiculous), people still used they inflating currency, but the de-fact spread on the buy/sell was so large that traders could make a profit even if they ended up with worthless currency at the end. So markets find a way, but it's hugely inefficient. (1)Holding too much foreign currency can present it's own issues. Storing it is difficult/risky and putting it in a dollar-account in a bank can be just as problematic. During the Argentinian default of the early 2000s, if you had money in a US-dollar account, the governnment confiscated it, converted your account Argentine pesos which was then promptly devalued.
