Or just save your money in the first world country with the most stable currency (dollars in the US as of now) like most of us third world citizens have been doing for a long time. We're not buying gold, and if the point ever comes that another currency is stronger, I guarantee the US will see capital flight like it's never seen before (hence all the wars would be my guess).
