Very comprehensive article, nothing to add, the only thing i would like to point out is that in the olden days many currencies were gold backed currencies and countries did not use to just go on printing currency to cover their deficit backlog. The Banks are lending out of thin air. They are giving away currency they really don't have. No one knows how long this will continue. Crytocurrencies seems to be a good bet as per experts (even though i don't know much about them.) And gold well its always useful to have precious metals, even in war like situations gold holds its value. Thanks for your insight.
