Very few people here in Argentina actually hedged against inflation with cryptocurrency, it's always USD, EUR, precious metals or high-ticket items (like guns). Regarding the subset of people that actually engages with cryptocurrency, most of them are in it to make a buck, not prevent their money from losing value. Similar story for some Venezuelan folks i know.

To be fair, cryptocurrency as a way for transferring money is excellent; people here move money with Bitcoin, which can be immediately converted into foreign fiat, avoiding the absurd exchange rates and taxes the government imposes. In my opinion that is something that could be done with any black/grey market tool for transferring value, and as I see it, currently cryptocurrency is filling that niche because of network effects, not because of its inherent properties.
