I thought that the country with the biggest gold reserve in the world is USA.
Favorising gold transactions over US dollar transactions won`t hit the US economy nore the value of US dollar.All the gold supporting countries want to avoid the future inflation, caused by the federal reserve money printing machine.That`s why they want to stop using USD for major transactions.
It seems to me that the value of gold is very exaggerated. In the future, perhaps some space probe will find a planet or an asteroid of gold, and then what? There is a planet made of diamonds why can't there be a planet made of gold? It's impossible to predict. Cryptocurrency mining is controlled and it seems to me that such an asset is more suitable for the reserve currency.
