While Bitcoin pioneered the cryptocurrency revolution, altcoins — alternative cryptocurrencies — have rapidly gained popularity, offering unique features and innovations.

1. Ethereum (ETH): Known for its smart contract functionality, it powers decentralized applications (dApps).
2. Litecoin (LTC): A faster, more efficient version of Bitcoin, ideal for quicker transactions.
3. Ripple (XRP): Designed for global payments, facilitating real-time international transfers.
4. Cardano (ADA): A research-driven blockchain focused on sustainability and scalability.
5. Solana (SOL): Known for high-speed, low-cost transactions, making it popular for DeFi and NFTs.

Altcoins bring diversity and innovation to the crypto market. Exploring them can open up new opportunities for investors beyond Bitcoin.
