[via PDK] I can tell you that anytime in the past the countries that revalued their currencies and had large denomination bills…they were given a certain time period in which you have to redeem them before they are considered worthless…If you want to hang on to them…it’s up to you…but if they tell you in 90 days (example) those notes are worthless…you may have time to hang on to them for a bit to see if the rate increases… it all depends on how much you want to gamble.
