dont know if it was max keiser or maybe it was mcaffee...
It's going to happen real slow, and then it will be all of the sudden.
When Ecuador (the country where I'm now) collapsed it's currency, it happened within a week. But it had been limping badly for years.
I was also considering this as a possibility but it is highly unlikely.
USD is way too connected to everything for this to happen.
It can't be compared to any other fiat currency in existence at the moment.
Unless a more stable currency magically pops up and drains USD it can't happen.
This is why other lesser fiat currencies tend to go belly up so fast; everyone gets USD.
