What Are Virtual Currencies?
Virtual currencies (also called digital currencies) are intangible forms of money. Unlike traditional fiat currencies (e.g., USD, EUR) issued by central banks, virtual currencies:
- Lack physical form.
- Are not government-issued.
- Operate globally (though adoption and utility lag behind fiat currencies).
Types of Virtual Currencies
- In-Game Currencies: Used exclusively within specific virtual environments (e.g., online games).
- Closed-Loop Virtual Currencies: Redeemable for goods/services within limited ecosystems (e.g., Microsoft Points, Amazon Coins).
- Cryptocurrencies: Decentralized digital currencies secured by cryptography and blockchain technology.
This article focuses on cryptocurrencies.
Key Features of Cryptocurrencies
Cryptocurrencies (or "crypto") are digital assets secured by cryptography and powered by blockchain technology. Unlike traditional banking systems, crypto transactions:
- Are peer-to-peer (no intermediaries like banks).
- Record permanently on public ledgers (blockchains).
- Operate 24/7 without banking holidays.
Core Characteristics:
- Decentralization: No central authority controls issuance or transactions.
- Digital-Only: Exist solely in electronic form.
- Immutable Records: Blockchain data cannot be altered retroactively.

How to Trade Cryptocurrencies: Exchanges Explained
Cryptocurrency exchanges facilitate buying/selling. Two primary types exist:
1. Centralized Exchanges (CEXs)
- Pros: High liquidity, user-friendly, regulated (some).
- Cons: Custodial (users don’t control private keys), hacking targets.
- Examples: Binance, Coinbase.
2. Decentralized Exchanges (DEXs)
- Pros: Non-custodial, enhanced privacy.
- Cons: Lower liquidity, complex for beginners.
- Examples: Uniswap, PancakeSwap.
