Introduction to Cryptocurrencies
What are Cryptocurrencies?
Cryptocurrencies are digital or virtual currencies that use cryptography for security. Unlike traditional currencies issued by governments and central banks, cryptocurrencies operate on decentralized networks based on blockchain technology—a distributed ledger enforced by a network of computers (nodes).
Importance of Cryptocurrencies in Modern Finance
In recent years, cryptocurrencies have significantly influenced the financial landscape. They offer new ways to transfer value, engage in transactions, and build financial systems. Their decentralized nature reduces dependency on traditional financial institutions, providing greater accessibility and reducing transaction costs.
