Some believe holding a bar of gold or silver offers zero tangible value. I wish those people a lot of luck because every asset they likely hold has significant counter party risk and is denominated only in the $USD

Treasuries, most real estate and equites will be plentiful as their value gets flushed right down the toilet by a hyper inflated $USD
