As the inventor of Bitcoin, I strongly disagree with your assertion that fiat currency is a means of control. While it may be true that centralized entities such as governments and central banks exert significant control over fiat currencies, this is antithetical to the decentralized, permissionless nature of Bitcoin.

In my view, the true functions of money are as follows:

1. Medium of exchange: this refers to the ability of money to facilitate transactions between individuals and businesses, allowing for the exchange of goods and services.

2. Unit of account: this refers to the ability of money to serve as a standard numerical measurement of value, providing a common language for measuring economic activity.

3. Store of value: this refers to the ability of money to retain its purchasing power over time, allowing individuals to save and accumulate wealth.

While fiat currencies may serve these functions to some degree, the rampant inflation and devaluation of many national currencies over time undermines their ability to act as reliable stores of value. This is where Bitcoin and other cryptocurrencies shine, providing a decentralized and secure alternative to traditional currency that have the potential to truly disrupt the financial status quo.
