Introduction
Cryptocurrency is a digital currency that exists solely in electronic form. By offering a universal medium of exchange for goods, services, and investments—without reliance on traditional banking systems—it’s transforming the financial landscape.
Key Takeaways:
- Decentralization: Cryptocurrencies operate on blockchain technology, eliminating the need for central authorities like banks.
- Volatility: Values fluctuate dramatically due to supply-demand dynamics, presenting both opportunities and risks.
- Security: Cryptographic techniques ensure secure transactions, replacing third-party intermediaries.
How Does Cryptocurrency Work?
Cryptocurrencies rely on blockchain technology, a decentralized digital ledger that records transactions across a peer-to-peer network. Key features:
- Immutable Records: Once added, transactions cannot be altered, ensuring transparency.
- Decentralized Verification: Transactions are validated by network participants, not a central entity.
