Cryptocurrency is a digital or virtual currency that uses cryptography for security. Unlike traditional currencies, cryptocurrencies are decentralized and operate on blockchain technology—a distributed ledger managed by a network of computers.
Bitcoin, the first and most well-known cryptocurrency, was introduced in 2009 by an anonymous entity known as Satoshi Nakamoto. It laid the foundation for a new era of digital currency operating independently of central authorities.
Key Takeaways
- Bitcoin vs. Altcoins: Bitcoin is the pioneer cryptocurrency with decentralized blockchain technology, while altcoins offer varied functionalities like smart contracts (Ethereum) or faster transactions (Litecoin).
- Bitcoin’s Unique Features: Fixed supply of 21 million coins, proof-of-work security, and attributes like scarcity and divisibility.
- Market Leadership: Bitcoin dominates in market capitalization and recognition, often termed "digital gold."
- Ethereum’s Role: The second-largest cryptocurrency, Ethereum enables decentralized applications (dApps) via smart contracts.
Understanding Bitcoin’s Uniqueness
Bitcoin’s creation revolutionized finance by introducing decentralization. It operates without central banks, leveraging blockchain for transparency and censorship resistance.
Core Features of Bitcoin
- Decentralization: No single entity controls the network.
- Fixed Supply: Capped at 21 million coins, ensuring scarcity.
- Proof-of-Work (PoW): Miners validate transactions, securing the network.
- Pseudonymity: Transactions are transparent yet privacy-friendly.
Economic Principles
Bitcoin embodies sound money principles:
- Scarcity: Fixed supply contrasts with inflationary fiat currencies.
- Durability: Immune to physical degradation.
- Divisibility: Each Bitcoin splits into 100 million satoshis.
- Portability: Transferred globally without intermediaries.
