Since the dawn of time, forum members have debated whether Bitcoin is a commodity or a currency/money. Let's ignore what the courts might call it (who the hell knows), and examine it in terms of economics.
If we were fortunate enough to live in a world where the government had not destroyed everyones' economic education, we'd know that "currency" and "commodity" are not mutually exclusive concepts.
It's important to understand where money comes from, when it doesn't come from the diktat of kings. In a world without government monopolization of money, would we have money? Of course we would. But how, without coercion, would the marketplace know what to use as money?
First, let's define commodity. A commodity is a subcategory of "goods." Specifically, commodities are goods which have little or no "qualitative variation" across units of them. Coffee beans. Rice. Wheat. Gold. Iron. Every unit is more or less the same as every other. Cars, houses, and computers are not commodities. Sand would be considered a commodity but it is so common that nobody cares enough to trade futures on it =)
And now let's look at "money." If there is no money in an economy, people trade goods with each other in barter. What you find is that they will start accepting commodities in trade frequently, because they know they are more widely desired and tradeable. Coffee beans are more easily traded than sheep (because sheep are heavy and can't be cut in half). Eventually, that commodity which becomes most widely accepted in barter becomes the de facto "money." Societal markets may gravitate toward one or several forms of money - but always money emerges, and it emerges from its prior categorization as a commodity.
So we see that money IS a commodity - it is that most widely desired commodity. It is the commodity which everyone wants to use in exchange. Review the history of gold, as it was always a commodity and gradually was accepted to the point where it was used as money. But its use as money didn't suddenly remove the label of commodity from it. Gold is both money and commodity. (gold was not chosen arbitrarily either - it's specific properties have made it the best form of money).
Just as "skiing" is a subcategory of "sports," so too is "money" a subcategory of "commodity."
I didn't notice any problems with any of the above.
But...
So let's please stop debating whether Bitcoin is a commodity or a money. It is absolutely a commodity, for each bitcoin is equal to every other - and it is also money to the extent it is used as barter for payment. Bitcoin is already used in many transactions every day, and thus it is very clearly a money as well as a commodity.
Yes,
metaphorically speaking, bitcoins are fungible
like a commodity. But in reality, they are just meaningless numbers on a ledger that are subtracted from and added to, not traded as real commodities are. About the closest you can get to any part of this system being considered a commodity is that you are trading mathematical/cryptographic abilities to subtract from and add to meaningless numbers on a ledger.
We can argue whether it will continue to be a money, or will replace other monies, etc, but it is silly to ponder whether it's a commodity or a money.
It's both.
Actually, it's neither.
