Sure gold could lose 70% of it's value before then, but fiat is dead....
now you can say you were right no matter what happens.
fiat can be highly unstable, i wont say gold will not lose value if they pull some stunts but my point was gold should have a place in a balanced investment portfolio.
5 to 10% is reasonable.
gold is not dead, i know im going to be able to say i was right. 5 years from now you are going to be wonder why the hell gold is still being bought and sold, i wont be.
