What Are Virtual Currencies?
Virtual currencies (or digital currencies) are decentralized forms of money managed by non-governmental entities. They exist exclusively online and serve various purposes, such as:
- Loyalty points (e.g., airline miles).
- In-game currencies (e.g., Fortnite V-Bucks).
- Cryptocurrencies (e.g., Bitcoin, Ethereum).
The European Central Bank (ECB) defines them as "digital representations of value" that aren’t issued by central banks but are accepted as payment by specific communities.
Why Do Virtual Currencies Have Value?
Their value stems from trust within user communities. For example:
- Scarcity: Bitcoin has a capped supply (21 million), making it inherently valuable.
- Utility: Ethereum’s smart contracts enable decentralized apps (DApps).
- Decentralization: No single entity controls the network.
Types of Virtual Currencies
Convertible Virtual Currencies:
- Can be exchanged for fiat money (e.g., Bitcoin, Ethereum).
- Includes cryptocurrencies and institution-issued tokens.
Closed-Loop Virtual Currencies:
- Used within specific ecosystems (e.g., Amazon Coins, Facebook Credits).
In-Game Currencies:
- Limited to virtual environments (e.g., World of Warcraft Gold).
