The BRICS want to peg their money to a commodity—GOLD. This is what some Austrian's would call smart hard money, admittedly well-named too: GOLD and BRIC. And potentially, it would conspire to give them advantage over soft money competition, given that Russia and Iran (soon to be BRIC) alone have over 40% of the world's natgas, and China has Arab friends in the Middle-East, meaning they can replace the petrodollar with the PetroBRIC. The rest of the world is in trouble.
This is fucking stupid
Pegs are bullshit. They require you peg the currency to a fixed amount of the commodity, then go into Forex markets and operate an industrial-grade currency manipulation campaign to make certain the peg stays rangebound.
And that's not the biggest problem. You can't ever be in a situation where the market capitalization of yours truly—Bitcoin—flips the market capitalization of gold. Otherwise you have money pegged to a weaker commodity. Also, the whole purpose of the petrodollar as a gold replacement for the US is that it was a much better mechanism to absorb monetary inflation, where the expansion of energy was necessarily an expansion of the USD. PretroBRIC is too late for that game. The fastest growing forms of energy are green. Bitcoin uses electricity, electricity doesn't require fossil fuels. The BTC/USD pair is a base money, quote currency pair—not a peg.
The final slap is that gold can literally get its monetary premium rekt forever with the harder commodity, when Allies collude London Gold Pool 2.0 style, and drip-leak-dump their gold reserves on the open market.
