Questions & Answers

The perception of value plays a critical role in the functionality of money. As long as everyone recognizes a form of money to have value, it can be used to facilitate trade and repay debts. This perception allows individuals to trust that the currency can be exchanged for goods and services, maintaining its status as a medium of exchange and store of wealth.

Q: What are the vulnerabilities associated with fiat money?

Fiat money, the type of money not backed by any tangible asset, is susceptible to vulnerabilities.

Money has evolved in terms of its form and underlying value. Initially, money was often backed by something of value, such as gold or any tangible asset.

The evolution of money is ongoing and subject to changes in societal needs and perceptions of value.

Q: What is the future of money?

The future of money is uncertain but likely to continue evolving. It will be shaped by various factors such as technological advancements, economic systems, and societal preferences. Cryptocurrencies like Bitcoin have emerged as alternative forms of money, indicating a potential shift away from traditional fiat currencies. However, the fundamental functions of money, as a medium of exchange and a store of wealth, will likely remain crucial regardless of its future form.
