What Is Bitcoin?
Bitcoin (BTC) is the world's first and most prominent cryptocurrency. The name combines "bit" (a digital storage unit) and "coin," representing a virtual currency existing solely as a cryptographic string. Unlike traditional fiat currencies, Bitcoin operates independently of governments and banks, leveraging decentralized technology.
Key features:
- Limited supply: Capped at 21 million coins, making it inflation-resistant.
- Decentralized: Managed by a peer-to-peer network, eliminating intermediaries.
- Founder: Created in 2009 by the pseudonymous Satoshi Nakamoto in response to the 2008 financial crisis, aiming for a transparent, secure, and tamper-proof transaction system.

How Does Bitcoin Work?
Bitcoin transactions rely on blockchain technology:
- Transaction blocks: Data blocks record all transactions within a timeframe.
- Verification: Network nodes validate each block’s accuracy.
- Immutable ledger: Approved blocks join the blockchain, a permanent, public record of all transactions.
This system ensures security, transparency, and resistance to fraud.
Disadvantages of Bitcoin
Despite its advantages, Bitcoin has notable drawbacks:
- Volatility: Extreme price fluctuations pose risks for investors. Regulatory bodies like the Bundesbank and BaFin caution against speculative investments.
- Anonymity misuse: Bitcoin’s pseudonymity makes it a tool for illegal activities (e.g., Darknet transactions or ransomware payments).
