In Zimbabwe US dollars are banked, ie confiscated, and turned into 'electronic' US dollars for which the lucky owner gets 2 'electronic' dollars. Thus Bitcoin in Zim, is 2 electronic US dollars for every real US dollar and thus double the 'dollar' price. Hard to believe but true.
So if you sold you Bitcoin there for double the US rate you would end up with double in 'electronic' US Zimbabwe-ised dollars. No such a great deal.
