Understanding Bitcoin (BTC)
BTC is the abbreviation for Bitcoin, the world's first decentralized digital currency and the most valuable cryptocurrency by market capitalization. Launched in 2009 by the pseudonymous creator Satoshi Nakamoto, Bitcoin operates on blockchain technology, offering unique features like decentralization, pseudonymity, and immutability.
Core Characteristics of Bitcoin
- Decentralization: Unlike traditional currencies, Bitcoin has no central authority. Transactions are verified by a distributed network of nodes using blockchain technology.
- Mining: New Bitcoins enter circulation through mining — a process where powerful computers solve complex algorithms to validate transactions and secure the network.
- Transactions: Bitcoin transfers occur peer-to-peer via the blockchain, ensuring transparency and security without intermediaries.
- Volatility: Bitcoin's price fluctuates significantly due to factors like market demand, regulatory news, and macroeconomic trends.
- Storage: Users store Bitcoin in digital wallets, which come in various forms (e.g., hot wallets for frequent access, cold wallets for enhanced security).
Bitcoin vs. Traditional Currency: Key Differences
| Feature | Bitcoin | Traditional Currency |
