Welcome to Lesson 1 of the Cryptocurrencies series. In this lesson, we explore the fundamental question: What is cryptocurrency? We dive into its origins, key features, and early digital currency experiments from 1980 to 2009. This foundational knowledge will help you understand how cryptocurrencies work and their role in the evolving financial world.
What is cryptocurrency? Simply put, it is a digital asset designed to function as a medium of exchange. Cryptocurrencies use cryptographic protocols—complex code systems that encrypt sensitive data—to secure transactions and currency units. These protocols rely on advanced mathematics and computer engineering principles, making duplication or counterfeiting virtually impossible. They also mask user identities, making transactions difficult to trace to specific individuals or groups.
Decentralization and Mining
Cryptocurrencies are decentralized. Their supply and value depend on user activities and embedded protocols rather than central banks or regulatory bodies. Miners, users with powerful computers, verify transactions and receive newly minted cryptocurrency units and transaction fees in return. This decentralized mining ensures currency stability and smooth operation.
Exchange and Finite Supply
Cryptocurrencies can be exchanged for fiat currencies like the US dollar, British pound, euro, or yen on special online markets. Most cryptocurrencies have a finite supply set by their source code, limiting how many units will ever exist. Mining becomes progressively harder until no new units are created. This finite supply makes cryptocurrencies deflationary, resembling gold and other precious metals more than traditional fiat currencies, which can be produced without limits.
Benefits and Risks of Cryptocurrency
Cryptocurrency users benefit from political independence and strong data security not available with fiat currencies. However, cryptocurrencies also carry risks such as illiquidity, price volatility, and vulnerability to hacking—especially at exchanges. Their frequent use in gray and black market transactions causes distrust or hostility from many governments. Although some view cryptocurrencies as investment opportunities, most financial professionals consider them speculative assets.
Early Digital Currency Experiments (1980-2009)
The idea of digital cash dates back to the 1980s with virtual tokens redeemable for fiat currency. David Chaum’s DigiCash was a pioneering internet money system in the Netherlands, featuring eCash. Despite media attention and a $180 million Microsoft offer, DigiCash failed due to strategic errors and regulatory pressures, leading to bankruptcy in 1998.
The next wave of digital money focused on web-based payment solutions. PayPal emerged as the clear winner, offering seamless peer-to-peer transfers on familiar browsers and convenient merchant payments. Another attempt, eGold, allowed gold deposits converted to digital credits, enabling cross-border payments. However, eGold shut down due to scams linked to Ponzi schemes.
