If you can pay in gold, now that will be interesting.
Gold is the money of the states, as a constitutional right. If states will have an income in gold they will be more inclined to pay things in gold. Which will create a gold standard.
What about Bitcoin? Bitcoin has no intrinsic value. Which will make it hard to be a store of value. And no, the fact that Bitcoin yielded a higher profit for investors these past years, doesn't make it a store of value. only a good investment.
