The mint certificates, the ETFs, and the coins in an investor’s safe – all of them – are valued, at least in large part, based on the most recent trade in the nearest delivery month on a futures exchange such as the COMEX. These “spot” prices are the ones scrolling across the bottom of your CNBC screen.
CNBC screen, not your bitcoin exchange screen.
This will only affect the price if they incorporate all bitcoin exchanges in their casinos.
Every country that have a (physical) gold exchange have it annexed and controlled by its stock exchange, which in turn is controlled by the State and hence is centralized. From there they have ETFs and futures.
Gold is not a decentralized trading system as bitcoin is, that is the reason why the price is always kept down. You dont have a independent gold exchange, as we have with bitcoin.
The only way they can affect the price is if the hedge funds buy bitcoins themselves and dump it when gambling for low prices in futures. But then theres the whales, and most whales are holders, and some of them just hate the centralized financial system.
