Bitcoin non sarebbe denaro per i teorici libertari capitalisti, ma dovrebbe esserlo è per quelli marxisti... <https://blog.p2pfoundation.net/face-value-bitcoin-proof-work-labour-theory-v...> Bitcoin was created to be a new kind of money rooted in a vision of a market not bound by geography, banks and governments. Despite the intentions of its creators, Bitcoin is not money. It was designed with a faulty understanding of money, and as a result has a bug, a kind of a short circuit that kick-started an asset bubble and that will eventually turn Bitcoin into a toxic asset. In order to to fix this bug we need to employ the labour theory of value. Writing at New Economic Perspectives, Eric Tymoigne, a research associate at the Levy Economics Institute, argues that the fair price of Bitcoin is zero. Tymoigne’s reasoning is based on the the fact that money is a financial instrument. The value of a financial instrument can come from being redeemable to its issuer, from providing an income stream or from having a collateralized value. For example US Dollars are redeemable against taxes. Bonds bear interest and stocks pay dividends. Gold coins contain gold, which can be sold as a commodity. Since Bitcoin is not redeemable, provides no income and has no collateralized value, it is worthless as a financial instrument. Thus, its “fair price” is zero. Eric concludes that “Bitcoins are purely speculative assets.”
From the point of view of modern finance, Bitcoin is not money at all.
[...] Ironically, while libertarian capitalist theories of money can not account for Bitcoin, Marxist theories of money can. The face value of Bitcoin represents a certain worth in terms of the labour time embedded in the computation power used to mine it. The Marxist theory of money is a Proof of Work theory. For Marx, the value of all commodities is not subjective, but objective; all commodities have a value that is created by the labour required to produce them. The reason that money can be used as a way to express the price of other commodities is because it represents a certain amount of labour, which is also what the worth of the other commodities is based on. As Marx states in Grundrisse “1/x ounce of gold is in fact nothing more than 1/x hours of labour time materialized, objectified.” For Marx, the value of all commodities is not subjective, but objective; all commodities have a value that is created by the labour required to produce them. The reason that money can be used as a way to express the price of other commodities is because it represents a certain amount of labour, which is also what the worth of the other commodities is based on. As Marx states in Grundrisse “1/x ounce of gold is in fact nothing more than 1/x hours of labour time materialized, objectified.” Marx illustrates that the face value of money is a rational number. It always represents a specific ratio. In the case of gold, Marx employs the ratio between the amount of gold and the amount of labour, the work:gold ratio. The value of the total volume of gold is derived from the amount of work required to produce it. [] While the libertarian capitalist theory is not useful in determining the value of Bitcoin, Marxist theory is. Bitcoin does not need to be backed or collateralized in any reserve of useful commodities, but instead in the labour time required to produce it. Proof of work. The Bitcoin software employs an algorithm that increases the difficulty of the work needed as more mining capacity is added to the pool to keep the rate at the current limit that is configured in the software. This means that while the face value of Bitcoin represents a certain worth in terms of labour, this worth is not consistent. There is no fixed ratio between work and coin. More work creates more value, but instead of creating more coins with the same value each, it creates the same number of coins. Each coin has more value.
