Gold has become much cheaper and it's still going down. This is partly due to the deflationary crisis that we're in right now.
Gold's correction was due to speculative selling, of course, but the deflation just dragged it further down.

Some experts are warning us that the deflationary period will be followed by a government-sponsored inflationary crisis. They will print, print and print their way into hyperinflation.

My guess is - hyperinflation or, at least very high inflation will happen before 2025, if not 2020.

Gold's price will increase after this deflation is over and the inflationary environment starts:
