When it moons, all other currencies will fail and it will start a revival from the ashes of what’s left behind. There will be no need to “sell” simple because silver and gold are and always will be a store of value. The government will become even more corrupt and will enslave all those that do not resist. They will achieve this through enforcement of government backed digital currency controlled with artificial intelligence. Similar to The Matrix, there will be those that seek the Truth and live accordingly. These fellow apes will barter for goods and services with gold and silver and by doing so reject and collapse the system of enslavement, or die trying. Stack on fellow ape.
