Usually this is where someone from Venezuela comes along and tells us that this is a tiny minority, and most people want US Dollars because they can actually use those.
but isn't any cryptocurrency still directly tied to some fiat currency? Unless everyone uses crypto then at some point it gets exchanged for dollars at which point the low value of the dollar in a place like Venezuela is realized and you're stuck in the same situation but with more hassle.
Crypto might well potentially shine under such circumstances, or under your view of what such circumstances might be, but the truth on the ground is apparently different.
