Introduction to Cryptocurrencies
Cryptocurrencies are virtual currencies that exist solely in digital form, secured by cryptography to validate transactions, enable payments, and regulate the creation of new monetary units. Unlike traditional currencies, they operate independently of central banks or government oversight.
How Cryptocurrencies Work
Decentralized Digital Assets:
- No central authority (e.g., banks) controls transactions.
- Peer-to-peer exchanges occur via blockchain technology.
Primary Uses:
- Alternative Payment Method: Accepted by select merchants globally.
- Investment Vehicle: Traded on exchanges for profit, though highly volatile.
Regulation Risks:
- Lack consumer protection mechanisms.
- Not backed by public institutions.
