Ya, conflict makes things tough...what works here for us...won't work for them. One day a person is banker in a wealthy family...the next there's nothing, no house, no electricity...and they're selling gas on a side road trying to eek out survival. As bullish as I am on Bitcoin et al, it's not a good conflict currency...but like you said...there's not really any good choice. Given the challenges of trading non-fiat currency in contingency environments...maybe there's a use case where there exists a hybrid of fiat/crypto currency? IDK.
