Exter
is dead. His pyramid is defunct. He was a former Fed official too.
Of course, John Exter lived in a very different era than today (he died 2006, three years before bitcoin), and while he did found the Central Bank of Sri Lanka, the exchange rate of the LKR to the USD has been declining ever since. So it's worse than the USD, which, according to recent news did it's worst year in 2017.
During his time, gold played a much more significant role in the global economy than it does at present. Canada recently sold almost all it's gold, and they have one of the top bullion refineries for bars, coins and rounds. It's not surprising that Exter viewed gold as being totally unique.
But that was before the advent of crypto.
After all, when 2008 happened, it wasn't gold that rallied. Gold actually declined by 20%+ at points during H2 2008.
Of course, this doesn't mean gold isn't viewed as a safe haven at all. There's just no gold standard now. Hasn't been since 1973 or 1976 in the US.
Most nations abandoned the gold standard as the basis of their monetary systems at some point in the 20th century.
You might want to look up George Franklin Gilder, tell me what you think of him.
