Virtual Currency vs. Cryptocurrency
Defining Virtual Currency
Virtual currencies are digital assets managed by non-governmental entities, existing solely online. Examples include:
- Airline miles
- Gaming tokens (e.g., Fortnite V-Bucks)
- Platform rewards (e.g., LINE Points)
Key Characteristics:
✔ Decentralized (no central bank oversight)
✔ Global usability
✔ Value derived from community trust
Cryptocurrency: A Subset of Virtual Currency
Cryptocurrencies use blockchain technology for:
- Secure, anonymous transactions
- Tamper-proof records
- 24/7 trading without intermediaries
Top Cryptocurrency Features:
🔹 Built on blockchain networks
🔹 Immune to inflation (fixed supplies like Bitcoin’s 21M cap)
🔹 High volatility = high reward/risk potential
Pro Tip: While "virtual currency" broadly includes rewards/game tokens, media often uses it synonymously with "cryptocurrency."
