Gold is useful as a semi-conductor. It seems to be more expensive by weight than most of the sh!t used in electronics.
Maybe you can familiarize me with gold's properties that make it useful - other than as a currency.
Because it's use as a currency is people are willing to trade things of value for it.
It's just not as useful as cryptocurrency.
I'm saying it's useful due to usability
At the most archaic level
Due to their physical properties there are limited elements that can be used to coin money.
And from these elements gold was attractive over stuff like platinum and silver, and additionally due to scarcity.
You can do your own research on gold currencies, the rise of silver currency, the accidental conversion to the gold backed currency...blah blah.
It's a bit comical, I know, but at the level of basic civilization it's quite practical and remains so.
But the bottom line is these things exist in the physical world and will continue to exist.
The blockchain can be hacked and corrupted.
And if you've ever worked at a place that's been hacked you could get a good feeling on the relative impermanence of digital items.
