Cryptocurrency is a digital or virtual currency that uses cryptography for security and operates independently of central authorities like banks. Built on blockchain technology, it enables secure online transactions, with Bitcoin being the most prominent example.
This innovative asset class is transforming global finance by decentralizing monetary control, but it also presents challenges like volatility, regulatory scrutiny, and security risks. Below, we explore its mechanics, types, pros and cons, and practical steps for investment.
Understanding Cryptocurrency
Cryptocurrencies are decentralized digital assets leveraging blockchain—a distributed ledger technology—to record transactions transparently across multiple computers. Key features include:
- Decentralization: No single entity (e.g., banks or governments) controls the network.
- Security: Cryptographic techniques safeguard transactions and prevent fraud.
- Transparency: All transactions are publicly verifiable on the blockchain.
How Bitcoin Works
Bitcoin (BTC), launched in 2009 by the pseudonymous Satoshi Nakamoto, introduced decentralized peer-to-peer transactions. It relies on:
– Mining: Miners use computational power to validate transactions and earn BTC rewards.
– Limited Supply: Only 21 million BTC will ever exist, creating scarcity.
