My biggest mistake was not buying it earlier when I knew about it. It was at a fairly low price and I could have made a nice profit.

There are 4 reasons:
-there was bullmarket from 2001-2010 what lifted the price from 250 to 1900 (a huge gain!)
-the crash was not there, the Fiat money market is still existing
-inflation went down instead of going up
-production costs are shrinking because of low energy prices (getting gold out of the earth costs a lot of energy)

America can have whatever debt they want as long as they have strong army to protect them, they can print the dollars that they want and pay it easily because dollar printing does not depend on any assests
