What Are Cryptocurrencies?
Virtual Currency vs. Cryptocurrency
Virtual Currency: Any non-physical currency/token existing digitally (e.g., airline miles, game coins, LINE Points).
Cryptocurrency: A subset of virtual currencies, created using cryptographic algorithms without centralized authority (e.g., banks). The technology behind it is blockchain (explained later).
Stocks vs. Cryptocurrencies
| Feature | Stocks | Cryptocurrencies |
|------------------|-------------------------|---------------------------|
| Ownership | Partial company ownership | Purely investment |
| Regulation | Strict (e.g., insider trading laws) | Evolving (varies by region) |
| Trading Hours| Market hours (e.g., NYSE 9:30 AM–4 PM ET) | 24/7, year-round |
| Entry Cost | Minimum 1 share (e.g., Tesla: ~$800/share) | As low as $0.01 fractions |
| Volatility | Moderate | High |
Why Invest in Cryptocurrencies?
- High Returns: Ethereum surged from $236 (2020) to $1,700 (2021)—a 6x increase.
- Low Barrier to Entry: Invest with as little as $100 vs. traditional assets.
- 24/7 Trading: Trade anytime, unlike stock markets.
- Growth Potential: Crypto is still in early stages, akin to buying tech stocks in the 1990s.
