I wonder if keeping the equivalent of $10k USD in something else might be a good "get the hell out of here and survive for three months elsewhere" hedge for people with a bit of cash who aren't too tied down to their local economy. You can use Elance, Odesk, etc to freelance from anywhere if you've got some in-demand skills. Doesn't take much to survive in Thailand, just getting out and having rent/food money for a while could be huge in a meltdown. I've been thinking over where/how it'd make sense to take a position - Seems like dollars, euro, and sterling might all be linked a bit. Chinese RMB? Yen? Some eccentric country that's still gold-based and can't debase their currency?
