And by "tied to the dollar" I meant we assess btc at their USD value that day. Its not like we think of them in units of gold or something.
So, are you likewise depressed that the Big Mac is "tied to the dollar"? Or your flatscreen TV?
You can express anything of value in terms of anything else of value. You could say that the Big Mac buys 3.14 dollars, instead of the other way around. That doesn't make it "tied to" the currency, just expressed in terms of that currency.
At the current value of Bitcoins, they're worth about 2/5ths of an ounce of silver each. Happy?
