Cryptocurrency has become one of the hottest topics in today’s digital economy. As a form of digital or virtual currency secured by cryptography, it operates independently of central banks and offers revolutionary potential for transactions and investments.
This guide explores everything you need to know about cryptocurrency—from its basic definition to its types, functions, characteristics, pros and cons, and practical investment tips.
What Is Cryptocurrency?
According to Investopedia, cryptocurrency is a digital or virtual currency secured by cryptographic systems. Unlike traditional fiat currencies (e.g., USD, IDR), cryptocurrencies are decentralized and recorded on a blockchain—a distributed ledger technology that ensures transparency and immutability.
Key Features:
- Decentralized: No central authority (e.g., banks or governments) controls it.
- Blockchain-Based: Transactions are recorded in a public, tamper-proof ledger.
- Pseudonymous: Users transact under cryptographic addresses, not real-world identities.
