<p class="text-lg text-gray-700 dark:text-gray-300 leading-relaxed">
The evolution of money represents a progression towards greater convenience, efficiency, and abstraction.
It begins with the direct exchange of goods (Barter), which is inefficient due to the need for a 'double coincidence of wants'.
This led to the adoption of commodities with inherent value (Commodity Money), simplifying transactions but introducing issues of divisibility and portability.
Representative Money emerged as paper notes backed by these commodities, offering more convenience.
Fiat Money, the dominant form today, is declared legal tender by governments and derives its value from trust and acceptance, not intrinsic worth.
Digital and Electronic Money further abstract this, existing purely as electronic records managed by financial systems.
Finally, Cryptocurrencies represent a decentralized evolution, using cryptography and distributed ledgers, offering a new paradigm for value exchange outside traditional financial institutions.
Each stage builds upon the previous, addressing its limitations while introducing new characteristics and challenges.
