In my opinion... the US $ is the leading currency in the world and is used for 'International Settlements'.
When huge record amounts of 'new' $ are created out of thin air( trillions at a time) this WILL devalue the currency. Previously (in 2008) the new money went into the markets with huge effect but was largely unnoticed and had little effect on Main St.. But this time it is being sent directly to the public and into Main St.. This will cause considerable inflation and the traditional place to put your money under these circumstances is into Gold. Those that understand what is actually happening are hedging by buying Gold - a traditional store of wealth. This will maintain the value of their wealth unlike currency which will loose value. There is also a great deal of talk about a currency "Reset", which has happened several times in the past, where the currency is revalued, causing a considerable loss of value. Buy physical Gold to hedge your wealth. ;-)
