You can get your information from the internet and goldbug websites but I prefer common sense.
How long have the USD, the British pound, the Swiss franc and other major currencies been around? Quite a long time, and they'll be around as long as you're stalking the Earth's surface I'll bet. Lots of people are very gullible and listen carefully to end-of-times nut jobs like Peter Schiff and Egon von Greyerz.
They change their minds after they lose sufficient money which is why the goldbugs I debated with in 2011 are no longer here.
