Are Bitcoin easier to get in Venezuela than other Bolivar alternatives?
But you can extrapolate from present-day Venezuela to future runaway-inflation crises, at which time (again, making an assumption here) bitcoin and the internet will be more accessible/prevalent.
Someone in country will likely be happy to exchange the Bitcoin for Bolivars at some discounted exchange rate, but that doesn't solve the problem of how they get Bitcoin.
You can have a few people working remotely for Bitcoin and the like, but that isn't going to support other people moving lots of money out of Bolivars.
