Taxes, for example, must be paid in fiat. And as a result of international trade agreements, oil is priced and traded in "[U.S.] Dollars per barrel," meaning that countries must purchase and maintain large reserves of U.S. Dollars in order to buy oil. For example, when Germany purchases oil it must sell Euros to buy U.S. Dollars in order to do so. This artificially created demand for the U.S. Dollar (specifically U.S. Treasury Bonds) is made possible by the "petrodollar." Basically, it works like this:long history as a standard store of value. Bitcoin isn't physical, so its value can't be measured by weight. Nor is it debt, so it isn't measured by interest rate. Bitcoins are basically data, but size doesn't matter; data size doesn't determine quantity of Bitcoin. So how is Bitcoin measured and why is it valuable? Bitcoin is measured by its own finite quantity and valued for its intrinsically valuable function. The Bitcoin protocol has immense intrinsic value as a self-regulating frictionless payment network affordable to almost anyone. Here is a technology that allows anyone to send any amount of money to anyone else in the world at virtually no cost with nothing more than an Internet connection or smart phone. Bitcoin, like the Internet, is one of those innovations that can break down barriers; information barriers in the case of the Internet, and financial barriers with Bitcoin. What I mean when I say that "Bitcoin is measured by its own finite quantity" is that the value of a single Bitcoin is measured against the strict limit of 21 million Bitcoins that can ever be produced. It is true that there will ultimately be less than 21 million coins at the end of Bitcoin's production (approximately scheduled for the year 2140) due to accidental loss or destruction of coins, but let's just say 21 million to keep it simple. The total intrinsic value of Bitcoin as a self-regulating frictionless payment network is measured relative to the strict limit of 21 million Bitcoins and in fact contributes to Bitcoin's value by limiting supply.

While this number may seem small, it may one day be a tiny sliver of an unimaginably immense pie. After all, it is difficult to quantify the total benefits of the Bitcoin protocol (size of the pie) when many of those benefits have yet to be developed or discovered. These developments and discoveries may enlarge the Bitcoin pie to the point where there would be enough pie to cure hunger. And if that day ever comes, a tiny sliver of pie may be more than even Homer Simpson could eat.
