Bitcoin remains the most established and popular cryptocurrency, but the digital asset space extends far beyond BTC. Thousands of alternative cryptocurrencies—commonly called altcoins or alts—offer diverse functionalities, from smart contracts to decentralized finance (DeFi). This guide explores altcoins’ definitions, history, top projects, risks, and buying strategies.
What Are Altcoins?
Altcoins ("alternative coins") are all cryptocurrencies except Bitcoin. Most aim to improve upon Bitcoin’s limitations or serve niche use cases, such as:
- Consensus algorithms: Proof-of-Stake (PoS), Delegated Proof-of-Stake (DPoS).
- Transaction efficiency: Faster speeds, lower fees.
- Specialized utilities: Oracles (Chainlink), AI integration, privacy features.
Over 10,000 altcoins exist, though many lack real-world utility or fade into obscurity.
