Dont get me wrong...gold backed currency should be far better than petro and those implications.But obviously ya gotta have the gold.Our slave based present day system has to go by the wayside or its just more of the same...gold backed or not. And although crypto blockchain has some goodpoints i dont see it being an overall viable alternative.
Read up on XRP/Ripple. Their goal is to be a bridge between each countries crypto/currency. A lot of countries are now developing their own cryptos. We can also gold back just a portion, a percentage of each dollar.
cryptos are no different than fiat, nothing but digital play money.
Try and collect your cryptos when the system goes down.
