What exactly is the use case:
Around five thousand years back ; an Angel decended to earth .. along with his fairy they brought 21 million kilos of gold ..the most precious gift for the earthlings - they thought ..
What do we do with it ? - asked the humans - can we buy coffee ?
No - said the Angel - for that you will need to come to heaven ๐
Since then , humans are hoarding gold - as a store of value !
