Countries that don't have reliable currencies are countries like South Sudan and Somalia. Do you really expect illiterate people (3 in 4 women in Somalia are illiterate, 1 in 2 men) to use Blockstream?
You can tell that Bitcoin, and its advocates, are from developed countries. No one who has lived in a developing country and seen crushing poverty would make such arguments.
I'd suggest keeping it in USD or other hard currency. Bitcoin provides no advantages in obtaining/transacting hard currency relative to other currencies, nor any stability while holding it. Either way you are going to a black market, and you are paying real, unaffordable conversion rates compared to transacting in (worthless) hyperinflationary currency.
The bitcoin guy is not going to accept 1 Zimbabwe dollar to 1 USD any more than your black market dealer who has USD. The real currency conversion rate is the problem, not the act of obtaining actual hard currency.
yes, there are a lot of fungible ways to transfer hard currency over the internet... once you acquire it.
again: acquiring it is the hard part, because nobody wants to trade a zimbabwe dollar for a USD.
Bitcoin does nothing to help your zimbabwe dollars be less worthless than they are in USD, therefore they don't help the currency conversion process at all.
