What Is a Virtual Currency?
A virtual currency (also called a digital currency) is a type of digital money that exists solely in electronic form. It operates primarily online and is often centralized, meaning it is issued, managed, and controlled by governments or large institutions.
Types of Virtual Currencies
Virtual currencies can be broadly categorized into three types, each with distinct characteristics:
- Government-Issued Virtual Currencies: Typically electronic versions of fiat currencies, such as digital balances in online banking accounts.
- Corporate-Issued Virtual Currencies: Platform-specific tokens like P coins, LINE POINTS, or OPEN POINTS, used within certain ecosystems.
- Decentralized Cryptocurrencies: Unlike traditional virtual currencies, cryptocurrencies like Bitcoin, Ethereum, and Dogecoin operate on blockchain technology, enabling decentralized control.
What Is a Cryptocurrency?
Cryptocurrency (or "crypto") is a type of virtual currency secured by cryptography and built on blockchain technology. The first and most well-known cryptocurrency, Bitcoin, was introduced in 2008 by an anonymous entity named Satoshi Nakamoto.
Quick Formula: Cryptocurrency = Cryptography + Virtual Currency
Key Features of Cryptocurrencies
Blockchain-Based Technology
Cryptocurrencies rely on blockchain—a decentralized ledger system that records transactions securely and transparently.
Decentralization
No central authority (like banks or governments) controls cryptocurrencies, allowing peer-to-peer transactions.
Immutability
Transactions recorded on a blockchain cannot be altered or deleted, ensuring data integrity.
Transparency
All transactions are publicly verifiable, reducing fraud and corruption risks.
Inflation Resistance
Most cryptocurrencies have a capped supply, preventing devaluation through excessive issuance.
