Introduction to Cryptocurrencies
The meteoric rise of Bitcoin and other cryptocurrencies has captured global attention from investors, financial institutions, regulators, and media. While interest surges, grasping foundational crypto concepts remains challenging for many due to:
- Technical Complexity: Cryptographic terminology and software mechanics
- Experimental Nature: Open-source projects with evolving governance structures
- Philosophical Divide: Challenges traditional monetary paradigms
"Cryptocurrencies represent either the future of money or speculative bubbles—depending on who you ask."
Core Cryptographic Principles
Cryptocurrencies (or tokens) are digital currencies secured by:
- Cryptography: Encrypted transaction verification
- Blockchain Technology: Decentralized, immutable ledgers
- Distributed Consensus: Requires >50% network control to alter records
Unlike fiat currencies, cryptos operate without central authority. New coins enter circulation through:
| Method | Process | Examples |
|---|---|---|
| Mining | Competitive computational puzzles | Bitcoin, Litecoin |
| Pre-mining | Early creation before public launch | Often controversial |
