alt Hacker NewsThis is not a problem for finance bros, they would sell a discounted note that gave you "ownership" of the gold in 17 years at some discount on the current spot price of gold. So you'd get these things that 'mature' in 17 years and you know their going to be worth whatever the spot price of gold is then, so it becomes a simple problem of pricing the risk that gold will be worth something in 17 years (people by gold futures all the time which this basically is).
The treasury sells bonds that mature after X years. So I suspect something similar could happen. But further there could be refinement if the radioactive isotopes could interact chemically in ways that gold couldn't.
Then they could sell pure gold, and then hold the crap gold for 20 years and sell that later.
BTW, I was at Teardown.
