What Are Altcoins?
Altcoins are any cryptocurrencies other than Bitcoin. They range from Ethereum—the second-largest by market cap—to thousands of smaller projects. Altcoins often aim to improve upon Bitcoin's limitations (speed, scalability, use cases) or serve niche purposes like DeFi, gaming, or supply chain. While they can offer higher growth potential, they also carry greater risk. Understanding the basics in our what is cryptocurrency guide will help you evaluate them.

5. Polygon (MATIC): Ethereum scaling solution. Low-cost transactions. Widely adopted by enterprises and dApps.
6. Chainlink (LINK): Leading oracle network. Critical infrastructure for DeFi. Data feeds connect smart contracts to real-world data.
7. Polkadot (DOT): Multi-chain ecosystem. Enables interoperability between blockchains. Parachain auctions drive ecosystem growth.

Diversification Strategy
Don't put all your capital in one asset. Consider a core portfolio of Bitcoin and Ethereum, then allocate a smaller portion to altcoins based on your risk tolerance. Dollar-cost averaging can reduce timing risk. Store your holdings securely—see our best crypto wallets guide. For price outlooks, check our Bitcoin price prediction and Ethereum analysis.
