By driving the value down and hoarding when low and selling when high is the entire premise of money. It is when those who have been hoarding deliberately manipulate markets to deminish value so they can hoard even more that causes the havoc leaving Joe nobody struggling to to get by with a low value dollar and high priced goods.It doesn't matter what is used for a currency; gold, cheese, pencils, things that grow on trees, money..it doesn't matter. The only things that matter are what value is placed on it by the holders and how easy is it to trade.
Those who don't freak out or realize it's a scam are playing this game to their advantage are making off with the lion's share of the economy.
It happens every 22 years like clockwork.
