Honest question: how does one buy currency with gold even under current circumstances? Let’s even forget the doomsday for a moment.
OP mentions gold as safe non-crazy way to protect savings against long-term inflation and depressions. However, from what I understand, any outsider would be extremely lucky to sell it at a rate anything close to the market, and common sense suggests that if dollar plunges it’d become proportionately trickier.
If selling it isn’t as tricky as it seems, then the reverse question comes up: how to buy it now without being ripped off?
