Not saying it will go up 10-25 times (but bubbles generally do go up multiple times especially in equity markets - Nasdaq bubble went up 16 times).
No one has a crystall ball just that it might as conditons today are stronger than they were in the 1970's - no possibility of global Depression in the 1970's, US was a large creditor nation in 1980 - today it is the largest debtor nation the world has ever seen and in 1980 US interest rsates went over 15% which rewarded savers who reverted to cash and bonds.
It is the opposite today with today's interest rates are at 0% and the printing presses are printing at rates never seen before - quantitative easing and debasement.
Just might be an idea just to diversify a little cancan . Even if gold does not go up you will have own one asset that is inversely correlated to property , equities and the most importantly the economic cycle.
